+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international! The Free Translation Project is
+a way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages. A few packages already provide translations for their
+messages.
+
+ If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site. But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+ Installers will find here some useful hints. These notes also
+explain how users should proceed for getting the programs to use the
+available translations. They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+ When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used. The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+1.1 Quick configuration advice
+==============================
+
+If you want to exploit the full power of internationalization, you
+should configure it using
+
+ ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed. So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation. Future versions of GNU `gettext' will
+very likely convey even more functionality. So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+ So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+1.2 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language. Most such
+packages use GNU `gettext'. Other packages have their own ways to
+internationalization, predating GNU `gettext'.
+
+ By default, this package will be installed to allow translation of
+messages. It will automatically detect whether the system already
+provides the GNU `gettext' functions. If not, the included GNU
+`gettext' library will be used. This library is wholly contained
+within this package, usually in the `intl/' subdirectory, so prior
+installation of the GNU `gettext' package is _not_ required.
+Installers may use special options at configuration time for changing
+the default behaviour. The commands:
+
+ ./configure --with-included-gettext
+ ./configure --disable-nls
+
+will, respectively, bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+ When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this. This might not be desirable. You should use
+the more recent version of the GNU `gettext' library. I.e. if the file
+`intl/VERSION' shows that the library which comes with this package is
+more recent, you should use
+
+ ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+ The configuration process will not test for the `catgets' function
+and therefore it will not be used. The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+ Internationalized packages usually have many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language. Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package. However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.3 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
+and `CC' is an ISO 3166 two-letter country code. For example, let's
+suppose that you speak German and live in Germany. At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+ You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries. For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
+country code serves to distinguish the dialects.
+
+ The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc. On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
+locales supported by your system for your language by running the
+command `locale -a | grep '^LL''.
+
+ Not all programs have translations for all languages. By default, an
+English message is shown in place of a nonexistent translation. If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries. For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+ Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from `no' to `nb' recently (in 2003). During the
+transition period, while some message catalogs for this language are
+installed under `nb' and some older ones under `no', it's recommended
+for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
+older translations are used.
+
+ In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect. For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+1.4 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list. The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
+area.
+
+ If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended. For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+ subscribe
+
+ Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around. If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `translation@iro.umontreal.ca' to reach the
+coordinator for all translator teams.
+
+ The English team is special. It works at improving and uniformizing
+the terminology in use. Proven linguistic skill are praised more than
+programming skill, here.
+
+1.5 Available Packages
+======================
+
+Languages are not equally supported in all packages. The following
+matrix shows the current state of internationalization, as of July
+2006. The matrix shows, in regard of each package, for which languages
+PO files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+ Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect. This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+ For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer. There might be an observable
+lag between the mere existence a PO file and its wide availability in a
+distribution.
+
+ If July 2006 seems to be old, you may fetch a more recent copy of
+this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date
+matrix with full percentage details can be found at

+
+1.6 Using `gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package. Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library. This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+ Once the sources are changed appropriately and the setup can handle
+the use of `gettext' the only thing missing are the translations. The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project. Therefore the information given above
+applies also for every other Free Software Project. Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

+* ABOUT BUGS
+
+Before reporting a bug, please check the list of known bugs
+and the list of oft-reported non-bugs (below).
+
+Bugs and comments may be sent to bonzini@gnu.org; please
+include in the Subject: header the first line of the output of
+``sed --version''.
+
+Please do not send a bug report like this:
+
+ [while building frobme-1.3.4]
+ $ configure
+ sed: file sedscr line 1: Unknown option to 's'
+
+If sed doesn't configure your favorite package, take a few extra
+minutes to identify the specific problem and make a stand-alone test
+case.
+
+A stand-alone test case includes all the data necessary to perform the
+test, and the specific invocation of sed that causes the problem. The
+smaller a stand-alone test case is, the better. A test case should
+not involve something as far removed from sed as ``try to configure
+frobme-1.3.4''. Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+
+
+* NON-BUGS
+
+`N' command on the last line
+
+ Most versions of sed exit without printing anything when the `N'
+ command is issued on the last line of a file. GNU sed instead
+ prints pattern space before exiting unless of course the `-n'
+ command switch has been specified. More information on the reason
+ behind this choice can be found in the Info manual.
+
+
+regex syntax clashes (problems with backslashes)
+
+ sed uses the Posix basic regular expression syntax. According to
+ the standard, the meaning of some escape sequences is undefined in
+ this syntax; notable in the case of GNU sed are `\|', `\+', `\?',
+ `\`', `\'', `\<', `\>', `\b', `\B', `\w', and `\W'.
+
+ As in all GNU programs that use Posix basic regular expressions, sed
+ interprets these escape sequences as meta-characters. So, `x\+'
+ matches one or more occurrences of `x'. `abc\|def' matches either
+ `abc' or `def'.
+
+ This syntax may cause problems when running scripts written for other
+ seds. Some sed programs have been written with the assumption that
+ `\|' and `\+' match the literal characters `|' and `+'. Such scripts
+ must be modified by removing the spurious backslashes if they are to
+ be used with recent versions of sed (not only GNU sed).
+
+ On the other hand, some scripts use `s|abc\|def||g' to remove occurrences
+ of _either_ `abc' or `def'. While this worked until sed 4.0.x, newer
+ versions interpret this as removing the string `abc|def'. This is
+ again undefined behavior according to POSIX, but this interpretation
+ is arguably more robust: the older one, for example, required that
+ the regex matcher parsed `\/' as `/' in the common case of escaping
+ a slash, which is again undefined behavior; the new behavior avoids
+ this, and this is good because the regex matcher is only partially
+ under our control.
+
+ In addition, GNU sed supports several escape characters (some of
+ which are multi-character) to insert non-printable characters
+ in scripts (`\a', `\c', `\d', `\o', `\r', `\t', `\v', `\x'). These
+ can cause similar problems with scripts written for other seds.
+
+
+-i clobbers read-only files
+
+ In short, `sed d -i' will let one delete the contents of
+ a read-only file, and in general the `-i' option will let
+ one clobber protected files. This is not a bug, but rather a
+ consequence of how the Unix filesystem works.
+
+ The permissions on a file say what can happen to the data
+ in that file, while the permissions on a directory say what can
+ happen to the list of files in that directory. `sed -i'
+ will not ever open for writing a file that is already on disk,
+ rather, it will work on a temporary file that is finally renamed
+ to the original name: if you rename or delete files, you're actually
+ modifying the contents of the directory, so the operation depends on
+ the permissions of the directory, not of the file). For this same
+ reason, sed will not let one use `-i' on a writeable file in a
+ read-only directory, and will break hard or symbolic links when
+ `-i' is used on such a file.
+
+
+`0a' does not work (gives an error)
+
+ There is no line 0. 0 is a special address that is only used to treat
+ addresses like `0,/RE/' as active when the script starts: if you
+ write `1,/abc/d' and the first line includes the word `abc', then
+ that match would be ignored because address ranges must span at least
+ two lines (barring the end of the file); but what you probably wanted is
+ to delete every line up to the first one including `abc', and this
+ is obtained with `0,/abc/d'.
+
+
+`[a-z]' is case insensitive
+`s/.*//' does not clear pattern space
+
+ You are encountering problems with locales. POSIX mandates that `[a-z]'
+ uses the current locale's collation order -- in C parlance, that means
+ strcoll(3) instead of strcmp(3). Some locales have a case insensitive
+ strcoll, others don't.
+
+ Another problem is that [a-z] tries to use collation symbols. This
+ only happens if you are on the GNU system, using GNU libc's regular
+ expression matcher instead of compiling the one supplied with GNU sed.
+ In a Danish locale, for example, the regular expression `^[a-z]$'
+ matches the string `aa', because `aa' is a single collating symbol that
+ comes after `a' and before `b'; `ll' behaves similarly in Spanish
+ locales, or `ij' in Dutch locales.
+
+ Another common localization-related problem happens if your input stream
+ includes invalid multibyte sequences. POSIX mandates that such
+ sequences are _not_ matched by `.', so that `s/.*//' will not clear
+ pattern space as you would expect. In fact, there is no way to clear
+ sed's buffers in the middle of the script in most multibyte locales
+ (including UTF-8 locales). For this reason, GNU sed provides a `z'
+ command (for `zap') as an extension.
+
+ However, to work around both of these problems, which may cause bugs
+ in shell scripts, you can set the LC_ALL environment variable to `C',
+ or set the locale on a more fine-grained basis with the other LC_*
+ environment variables.

+
+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ Change the way we treat lines which are not terminated by a newline.

+ line.
+ (execute_program): Commands `c' and `i' no longer call the
+ function output_line with chomped==FALSE; instead, they chomp
+ the text and call the function with chomped==TRUE.

+ calls ck_fwrite directly. Commands `e', `L' and `=' flush
+ the output stream at the end.

+ s/a*/x/g, gave `xbxxcx' rather than `xbxcx' (because an
+ empty string matched before the `c'. Fixed.
+

+
+2001-02-08 Paolo Bonzini <bonzini@gnu.org>

+
+Mon Aug 30 23:40:08 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.02.80 released
+
+ * sed/execute.c(do_subst): lib/regex.c(re_search_2) seems to
+ want one extra backreference register; humor it.
+
+ * sed/regex.c(compile_regex): work around some odd assumptions
+ that lib/regex.c(re_compile_pattern) makes about our desired
+ RE syntax.
+
+ * configure.in: tweaked version to 3.02.80; added new entries
+ to the ALL_LINGUAS definition.
+
+ * doc/sed.1, doc/sed.texi, BUGS: explicitly request the output
+ of sed --version in bug-reporting instructions.
+
+ * doc/sed.texi: the old "informal seders list" is dead; document
+ the new sed-users mailing list instead (under Other Resources).
+
+
+Thu Aug 19 23:27:54 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.h: Add explicit #include of "regex-sed.h" (rather
+ than relying on parent file doing so); change the "cmd_regex"
+ member of sed_cmd: make it a pointer (instead of a struct),
+ and change its name to cmd_subst; add prototypes for newly
+ exported functions bad_prog(), normalize_text(), compile_regex(),
+ match_regex(), and release_regex(); drop rx_testing variable.
+
+ * sed/compile.c: move the compile_regex() function to regex.c;
+ export bad_prog() and normalize_text() functions; eliminate the
+ rx_testing debris; rename the NOLEAKS symbol to more descriptive
+ DEBUG_LEAKS; make cmd_regex to cmd_subst fixes (see above);
+ make use of newly abstracted release_regex() function.
+
+ * sed/execute.c: abstract out the regex matching to
+ regex.c:match_regex(); NOLEAKS to DEBUG_LEAKS change;
+ cmd_regex to cmd_subst structure member name change.
+
+ * sed/execute.c(do_subst): use re_registers/regoff_t instead of
+ regmatch_t to hold the backreference registers, make "offset"
+ always be relative to the beginning of the string (rather than
+ a delta from "start"), defer some matching bookkeeping (e.g.,
+ not_bol_p) to match_regex().
+
+ * sed/sed.c(main): loose rx_testing variable; NOLEAKS
+ (aka DEBUG_LEAKS) code attempting to release
+ _nl_current_default_domain is problematic, so omit it.
+
+ * sed/regex.c: new file --- abstracts out the interface to the
+ regex engine so that less conditional code is required in
+ compile.c and execute.c, and so as to make a change of engine
+ easier; implements compile_regex() (which looks an awful lot
+ like the one that used to live in compile.c), match_regex(),
+ and (if DEBUG_LEAKS is set) release_regex().
+
+Sun Apr 18 04:40:46 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c(main): conditionalize calls to setlocale() and
+ textdomain() to only occur if their support is needed/wanted.
+
+Sun Apr 18 03:01:46 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ * bootstrap.sh: "foo || bar && baz" was not grouping like I
+ expected ("foo || (bar && baz)") under at least one shell,
+ so change the test for a pre-existing config.h file to an
+ if statement.
+
+ * bootstrap.sh: added -DUSE_REGEX_GNU_H option to the
+ compiler invocation, to ensure that we get a usable
+ regex library included.
+
+Sun Apr 18 02:59:42 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.h, sed/utils.c: conditionalized inclusion of <libintl.h>
+ to occur only if ENABLE_NLS is defined.
+
+Sun Apr 18 01:48:45 PDT 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(xofa,normalize_text,convert_number): change
+ name of xofa() function to convert_number(); change semantics
+ to do all of the work of the text->number conversion.
+
+ * sed/compile.c(normalize_text): add new \dDDD decimal
+ and \oOOO octal escapes.
+
+Sun Mar 28 21:05:07 PST 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c(main): if NOLEAKS is set, free up a word that
+ the call to textdomain() allocated.
+
+ * sed/execute.c(read_file_line): plug up (minor) memory leak:
+ if buffer.alloc==0 we may have malloc()'d 1 byte anyway,
+ so be sure to FREE(buffer.text) before calling line_init();
+
+Fri Mar 26 16:52:10 PST 1999 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(match_slash): somewhere between 3.02
+ and 3.02a we lost the ability to use a newline as
+ the s/// delimiter; restore this ability.
+
+ * sed/compile.c(compile_regex): forget about trying
+ to cache the compiled form of the last RE --- it
+ causes more problems than its worth. We now only
+ cache the source form.
+
+ * testsuite/help.good: update to reflect output containing
+ new options.
+
+Sun Dec 6 00:51:23 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/utils.c(ck_fwrite): fix i18n bug of using a printf
+ fragment of "item%s" to handle plural text.
+
+Mon Nov 23 11:03:40 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * doc/sed.1, doc/sed.texi: ran ispell over these
+ files to catch the more obvious typos...
+
+Sun Nov 1 00:09:07 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/execute.c(do_list): make a `lcmd_out_line_len'
+ (--line-length) of zero mean "infinite length",
+ i.e., "never wrap".
+
+Sat Oct 31 23:06:50 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c(match_an_address_p,process_files),
+ compile.c(compile_program): back out the "zero-address"
+ changes of 1998-09-27. It was a neat idea, but there are
+ too many dark corners which don't work well. The
+ special code for handling line ranges starting at
+ address zero (from 1998-08-31) are still there though:
+ this seems to work fine with no surprises.
+
+Sat Oct 31 22:18:59 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c, sed/sed.h, sed/execute.c: added new
+ `lcmd_out_line_len' variable. (Idea suggested by
+ Carlos J. G. Duarte <l38076@alfa.ist.utl.pt>.)
+ Also added ATOI macro (which uses strtoul() if available,
+ with fall-back to atoi()).
+ * sed/sed.c(main): attempt to use COLS environment variable
+ to set a reasonable `lcmd_out_line_len'; added -l/--line-length
+ command-line options to set the new `lcmd_out_line_len' flag.
+ * sed/sed.c(usage): documented new -l/--line-length options.
+ * sed/execute.c(do_list): use `lcmd_out_line_len' variable
+ instead of `LCMD_OUT_LINE_LEN'.
+ * sed/execute.c: deleted now obsolete LCMD_OUT_LINE_LEN define.
+ * configure.in: added strtoul to the AC_CHECK_FUNCS call.
+
+Sat Oct 31 21:37:17 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c, sed/sed.h, sed/execute.c: added new `force_unbuffered'
+ flag. (Idea suggested by Frank Strauss <strauss@escape.de>.)
+ * sed/sed.c(main): added -u/--unbuffered command-line options
+ to set the new `force_unbuffered' flag.
+ * sed/sed.c(usage): documented new -u/--unbuffered options.
+ * sed/execute.c: changed the name of the `is_tty' flag in struct
+ input to a more generic `no_buffering'; also removed HAVE_ISATTY
+ conditional on this member.
+ * sed/execute.c(slow_getline): removed HAVE_ISATTY conditonal
+ compilation of this function.
+ * sed/execute.c(output_line): if force_unbuffered is set,
+ then force a fflush() even if writing to stdout.
+ * sed/execute.c(open_next_file): added handling of the
+ new `force_unbuffered' flag so that slow_getline()
+ will always be used for input.
+ * sed/execute.c(read_file_line): changed the (conditionally
+ compiled) test of `input->is_tty' to (unconditionally)
+ use the new spelling `input->no_buffering'.
+
+Thu Oct 15 12:08:09 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: deleted AC_ARG_PROGRAM call; this is already
+ done for us by AM_INIT_AUTOMAKE, and we were winding up
+ with a doubled-transform.
+
+Sun Sep 27 01:42:42 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * compile.c(compile_program): remove special-case code for matching
+ address range with a `0' beginning.
+
+ * compile.c(compile_address): change default addr_number to
+ be a pragmatically impossible countT value, instead of zero.
+
+ * execute.c: spell macro REGNEXEC() unconditionally instead of
+ playing with conditional definition of regnexec() macro.
+
+ * execute.c(match_an_address_p): added third argument (and changed
+ callers in match_address_p). Added special code to ignore
+ non-numeric matches when processing "line zero".
+
+ * execute.c(process_files): added a "line zero" pass through the
+ commands script.
+
+Sun Sep 27 00:20:53 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * compile.c(xofa,normalize_text): new functions.
+ * compile.c(compile_regex): cache last_compiled_re (with its
+ associated flags); add POSIXLY_CORRECT behavior for empty RE.
+ Make use of the new normalize_text() function.
+ * compile.c(setup_replacement): Make use of the new normalize_text()
+ function.
+
+Sat Sep 26 22:59:13 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * lib/regex-gnu.h: added missing prototype for regncomp().
+
+Mon Sep 14 20:47:23 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c(main): use EXIT_SUCCESS instead of 0, in case
+ we are built on a system (such as VMS) where EXIT_SUCCESS
+ is distinct from 0.
+
+Wed Sep 9 22:17:28 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/Makefile.am: added -I../intl the INCLUDES line; if we are
+ building in a directory outside the source tree and the system
+ we are building on does not have a <libintl.h> header, then
+ the build was failing, because libintl.h is a build-time
+ constructed source file.
+
+ * configure.in: tweaked version to be 3.02b.
+
+Wed Sep 9 19:28:14 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.02a released
+
+ * sed/compile.c(mark_subst_opts,read_label,compile_program):
+ wherever we accept a ; as a command terminator, also allow a } or
+ a # to appear. (This allows for less cluttered-looking scripts,
+ such as: sed '/foo/{x;G}' (instead of: sed '/foo/{x;G;}').)
+
+Wed Sep 9 18:17:07 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(compile_regex): use regncomp() instead
+ of regcomp(), so that a script with NULs in its REs
+ will work in the expected manner.
+
+ * sed/compile.c(ADDNUL,REGNCOMP): added support macros
+ for above.
+
+ * lib/regex.c(regncomp,regcomp): added regncomp() and
+ made regcomp() a simple wrapper function.
+
+Mon Aug 31 21:48:30 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c(compile_program): if the first address of
+ a range is the number 0 (or a 0~N sequence), start
+ out in the "a1_matched" state. This allows one
+ to match an initial chunk of a file without undue
+ convolutions for handling the case where the match
+ for the end of the sequence happens to be the first
+ line.
+
+Sun Aug 16 03:34:25 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(snarf_char_class,match_slash): simplify
+ handling of "premature newline" error. Also, get the
+ line number right in the error message if we encounter
+ a "premature newline" during char-class snarfing.
+
+Sun Aug 16 02:59:20 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c: added N_() markers and corresponding gettext()
+ (er, _()) calls.
+
+ * Merged in i18n contribution from Erick Branderhorst
+ <Erick.Branderhorst@asml.nl>. His ChangeLog entry
+ for the changes I've incorporated so far:
+
+1998-07-24 Erick Branderhorst <Erick.Branderhorst@asml.nl>

+
+Fri Aug 14 13:52:57 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * Merged code from 3.02 with a branched development
+ tree from late May; the following (out-of-order)
+ changelog entry is from the branched tree.
+
+Sat May 30 12:23:16 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c, sed/execute.c: added (conditional on NOLEAKS macro)
+ code to free all dynamically allocated memory.
+
+ * sed/sed.c, sed/compile.c, sed/execute.c: much shuffling
+ of code --- ordered functions such that no forward
+ declarations are necessary, and placed all static prototypes
+ immediately before the actual function definition.
+ This accomplished two things: first, I find the new ordering
+ a more natural way to read the code than the previous
+ ordering, and second, the new ordering give the compiler
+ a better opportunity to discover inlining possibilities.
+ (The odd "prototype declaration+old-style definition"
+ style is used because I feel it is the least ugly way
+ of supporting K&R1 C while still getting the benefit of
+ prototypes when they are available.)
+
+ * sed/basicdefs.h: added MEMCPY() macro to hide the VCAST()s
+ that ought to be used with memcpy().
+
+ * sed/execute.c: Change calls to memcpy() to go through the
+ new MEMCPY() macro. Various prototypes: elide variable name
+ if it does not add any human-useful documentary information
+ to the bare type.
+
+ * sed/sed.c(main): Updated calls to compile_string() to add third
+ (length) argument. Changed call to obsolete close_all_files()
+ to a call to the new finish_program().
+
+ * sed/sed.c(map_file): Attempt to clean-up how "size" gets
+ cast and tested; remove spurious S_ISREG test (just let
+ mmap() fail if it doesn't support the underlying file type).
+
+ * sed/sed.c: Deleted old RX library stub declarations.
+
+ * sed/sed.c(map_file,unmap_file): added VCAST()s to the
+ mmap()/munmap() calls.
+
+ * sed/utils.c(ck_fclose): added support for ANSI C
+ functionality where passing a NULL argument means
+ to fclose() _all_ open streams. (Well, almost.
+ Only closes streams which were previously ck_fopen()ed,
+ as I don't care to figure out how to autoconf-detect
+ whether fclose(NULL) is properly supported on a given
+ platform.)
+
+ * sed/sed.h: Renamed `struct text_buf' member `text_len'
+ to `text_length'. Abstracted out `enum addr_types'
+ from `struct addr'; added new enum types num2,step,step_mod;
+ renamed mod to num_mod. De-unionized the regex,number,
+ {modulo-offset/step} components of `struct addr', in
+ anticipation of new features. Changed type of `a2' member
+ of `struct sed_cmd': now a pointer to save space.
+ Abstracted out `struct replacement' from `struct subst'.
+ Cleaned up declaration of `x' union of `struct addr'.
+ Fixed prototype for compile_string(). Replaced prototype
+ for old close_all_files() with one for new finish_program().
+
+ * sed/sed.h, sed/compile.c, sed/execute.c: changed to
+ simplify the data structures used for branches and
+ command blocks: simplified `struct vector'; made
+ `struct label' local to compile.c; `struct sed_cmd'
+ was modified to support a simpler design for branches
+ and blocks.
+
+ * sed/execute.c: Conditionally added ADDNUL() macro so that
+ the function call overhead is only incurred if nul_append()
+ _must_ be called. Made some commentary edits, including
+ typo fixes.
+ * sed/execute.c(resize_line): changed semantics of "len" argument
+ from "additional length" to "target length"; made
+ INITIAL_BUFFER_SIZE a minimum allocation length.
+ * sed/execute.c(str_append): adjusted to new resize_line()
+ semantics.
+ * sed/execute.c(line_copy): use FREE()+MALLOC() instead of
+ REALLOC() to avoid unnecessary copying of old text; add the
+ "try doubling first" allocation heuristic (just like
+ resize_line() does).
+ * sed/execute.c(line_exchange): new function.
+ * sed/execute.c(nul_append): make whole function (not just its
+ body) conditional on HAVE_REGNEXEC macro; adjust to new
+ resize_line() semantics.
+ * sed/execute.c(read_mem_line): use str_append() instead if
+ custom in-line code; compensate for new default of
+ "line.chomped = 0" in read_pattern_space() by setting
+ "line.chomped = 1" where appropriate.
+ * sed/execute.c(read_file_line): use different trigger to
+ determine that "buffer" is uninitialized, and do a full
+ initialization if required; use str_append() instead of custom
+ in-line code in two places; compensate for new default of
+ "line.chomped = 0" in read_pattern_space() by setting
+ "line.chomped = 1" where appropriate.
+ * sed/execute.c(output_line): don't bother calling ck_fwrite()
+ if length==0.
+ * sed/execute.c(release_append_queue): new function.
+ * sed/execute.c(dump_append_queue): use release_append_queue()
+ instead of in-line equivalent.
+ * sed/execute.c(read_pattern_space): conditionalize call to
+ dump_append_queue() for alleged performance reasons; changed
+ default "line.chomped" value to more common "1", and added an
+ assignment of "0" where this made a difference.
+ * sed/execute.c(match_an_address_p): deleted "is_addr2_p"
+ argument; reorder cases to match order in enum declaration; add
+ cases for new "addr_is_num2", "addr_is_step", and
+ "addr_is_step_mod" address types; alter nul_append() call to be
+ through ADDNUL() macro; fix to new struct member and enum
+ spellings in (formerly addr_is_mod); addr_is_num_mod case.
+ * sed/execute.c(match_address_p): remove oblsolete third argument
+ to calls to match_address_p(); alter references to sed_cmd
+ member a2 to reflect new pointer status; add new support for
+ a2->addr_type addr_is_step and addr_is_step_mod cases.
+ * sed/execute.c(do_subst): add NOLEAKS support logic; use
+ ADDNUL() wrapper to nul_append(); simplify replacement
+ expansion by using the new "struct replacement" data structure;
+ use line_exchange() function instead of custom in-line code.
+ * sed/execute.c(process_files): added NOLEAKS code.
+ * sed/execute.c(execute_program): updated implementations
+ of the `{', `}', `:', `b', and `t' commands; modified
+ `c' command gratuituosly; fixed potential memory
+ overrun in `D' command. Simplified how nonstandard
+ `loop increments' work. Use line_exchange() instead of
+ custom in-line code in 'x' case.
+ * sed/execute.c[EXPERIMENTAL_DASH_N_OPTIMIZATION conditional
+ code]: various modifications intended to keep this
+ code in sync with the new changes, but the code still
+ retains its previous bugs.
+
+ * sed/compile.c: use "exit(EXIT_FAILURE) instead of "exit(1)",
+ just in case we get compiled under VMS.
+ * sed/compile.c: Change type of prog_info.base to decrease needs
+ for casting; then elimiated the casts in question ;-).
+ * sed/compile.c: Added struct sed_label (moved from sed.h, then
+ modified).
+ * sed/compile.c: Removed "readit_p" flag from struct fp_list.
+ * sed/compile.c: Added module-global "blocks" variable.
+ * sed/compile.c: Extracted more error-message constant strings
+ to named variables.
+ * sed/compile.c(check_final_program): updated to
+ reflect new data structures and use new fucntions.
+ Added call to compile_regex() to release unneeded
+ memory.
+ * sed/compile.c: deleted obsolete new_vector() function;
+ abstracted new read_label() function; abstracted new
+ release_label() function; added new `blocks' module-static
+ variable.
+ * sed/compile.c(compile_program): updated implementations
+ of the `{', `}', `:', `b', and `t' commands; modified
+ initialization from NULL vector.
+ * sed/compile.c(compile_regex): added mechanism to
+ release memory consumed by the cached `last' RE.
+ * sed/compile.c(setup_jump,setup_label): updated
+ name (from setup_jump to setup_label) and prototype;
+ changed body to reflect data structure changes.
+ * sed/compile.c: Add OPEN_BRACE and CLOSE_BRACE macros for better
+ "vi" editing behavior.
+ * sed/compile.c(compile_filename,read_filename,get_writefile):
+ Replaced function compile_filename() with more orthogonal functions
+ read_filename(), get_writefile().
+ * sed/compile.c(compile_regex): Added ability to free the remembered
+ "last RE" in compile_regex (for benifit of "NOLEAKS" code).
+ * Made adjustments dictated by the change to struct sed_cmd which made
+ the a2 member a pointer-to-addr instead of an addr.
+ * sed/compile.c(setup_jump,read_label,setup_label,release_label):
+ Added functions read_label(), setup_label(), release_label(); deleted
+ function setup_jump().
+ * sed/compile.c(new_replacement,setup_replacement,release_replacement):
+ new functions.
+ * sed/compile.c: Adjusted to new spelling of text_buf member
+ ("text_length" instead of "text_len").
+ * sed/compile.c(new_vector): deleted function. (Due to new handling
+ of blocks, only one instance remained, and that one was just as
+ clear in-lined.)
+ * sed/compile.c(compile_string): Added third argument; it now
+ takes a counted string instead of a NUL-terminated string.
+ * sed/compile.c(compile_file): added variable "map_base" to
+ compensate for new type of prog_info.base.
+ * sed/compile.c(check_final_program): reflect new style of
+ handling blocks and struct sed_label.
+ * sed/compile.c(close_all_files,finish_program): replaced function
+ close_all_files() with more generic finish_program().
+ * sed/compile.c(read_text): added new feature: if first non-blank
+ character after the {a,i,c} command character is not "\", then
+ use the trailing text on that line as the (first) line of text.
+ Also added code conditional on NO_INPUT_INDENT to support the
+ "feature" of stripping leading blanks from each input line; I
+ do not read POSIX as permitting this behavior, nor do I think
+ it is a good idea, so it is disabled by default, but some have
+ argued that this blank-stripping is the "correct" behavior, so
+ I offer them the option of building their sed that way.
+ * sed/compile.c(compile_address): added xxx,+n and xxx,~n addressing;
+ simplified code.
+ * sed/compile.c(compile_program): added BAD_PLUS error detection;
+ adjusted to new cur_cmd->a2 pointer status; added addr_is_num2
+ detection; deleted pointless "a2->addr_number < a1.addr_number"
+ check (addr_is_num2 semantics handle this just fine); updated
+ code for '{', '}', ':', 'b', and 't' to reflect new design
+ of branch handling, including making use of new functions
+ related to the new design); added support for feature already
+ mentioned in read_text() where {a,i,c} commands are able to have
+ their text start on the same line as the command; changed some
+ error messages (hopefully for the better); localized variables
+ specific to individual commands (particularly 's' and 'y');
+ made use of new setup_replacement() function in 's' command.
+
+Mon Aug 10 19:58:49 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * doc/sed.texi, doc/sed.1: sedtut10.txt is apparently dead.
+ Deleted references to it and added a pointer to
+ http://seders.icheme.org/tutorials/. (Pointed out by
+ Joerg Heitkoetter <joerg@de.uu.net>.)
+
+Sat Aug 8 18:11:57 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * djgpp/config.btm: per request by Michel de Ruiter
+ <mdruiter@cs.vu.nl>, added "%1" to "%9" parameters.
+
+Mon Aug 3 11:44:55 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * doc/sed.texi: fix a couple of typos. (Submitted by
+ Alan Modra <alan@spri.levels.unisa.edu.au>.)
+
+Sat Aug 01 17:49:06 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.02 released
+
+ * configure.in: Because of code change in 3.01a, bump the
+ minor revision number for the release (now 3.02).
+
+Sun Jul 26 16:07:55 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01a released
+
+ * sed/compile.c(snarf_char_class): the POSIX char-class
+ recognition loop forgot to update its concept of "prev"
+ as the loop progressed.
+
+ * testsuite/Makefile.am: The dependency of version.good
+ on [testsuite/]Makefile introduced in the previous
+ release was botched -- it referred to "Makefile"
+ as "$(srcdir)/Makefile, which of course doesn't work
+ if you aren't building in the source tree.
+
+ * djgpp/Makefile.am: add forgotten "config.btm" EXTRA_DIST
+ member.
+
+ * configure.in: update version.
+
+Tue Jul 21 06:04:42 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01 released
+
+ * configure.in: mark as release version!
+
+ * Makefile.am: add BUGS and THANKS to the EXTRA_DIST target.
+
+ * testsuite/Makefile.am: add dependency of version.good
+ on [testsuite/]Makefile.
+
+Mon Jul 20 12:38:10 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * djgpp/config.btm: New file to support the 4DOS alternative
+ to command.com. (Sumitted by Eli Zaretskii on behalf of
+ an anonymous 4DOS user.)
+
+Fri Jul 17 00:36:34 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta18 released
+
+ * djgpp/config.sed: my "tweak" in beta17 was too
+ hastily considered. Back it out.
+
+ * configure.in: update to beta18.
+
+Wed Jul 15 01:02:15 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta17 released
+
+ * djgpp/config.sed: tweak/simplify s,,, commands at end.
+
+ * configure.in: update to beta17.
+
+1998-07-14 Eli Zaretskii <eliz@is.elta.co.il>
+
+ * djgpp/config.sed: Edit all the occurences of = in the context of
+ --option=value, including in the help messages, into
+ --option:value, but leave DOS-style d:/foo/bar file names intact.
+
+ * djgpp/config.bat: Use --srcdir:foo instead of --srcdir=foo.
+
+ * testsuite/Makefile.am (help, version): Remove temporary files
+ explicitly, don't use shell wildcards, so it works under DOS 8+3
+ limits.
+
+Thu Jul 9 13:06:00 PDT 1998 16:51:43 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta16 released
+
+ * djgpp/config.sed: tweak the configure script to use :
+ instead of = for --with-foo=bar option parsing, to
+ work around problems with how command.com handles =s.
+
+Wed Jul 8 16:51:43 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * djgpp/config.bat: correct inappropriate behavior that I
+ introduced in the beta13 changes (if first argument is
+ a directory, it needs to be handled as the --srcdir).
+
+ * testsuite/version.gin, testsuite/version.good, testsuite/Makefile.am:
+ Add target to automake to automatically update version.good
+ from (new file) version.gin, instead of hand-editing the version
+ number each release.
+
+ * testsuite/Makefile.am: miscellaneous gratuitious tweakage --
+ mainly adding $(RM) commands just because I didn't like
+ leaving the tmp* files from successful runs laying about.
+ Also some editorial comments.
+
+ * configure.in: update to beta16. Added and commented out
+ experiment with AC_OUTPUT() for testsuite/version.good.
+ Added code to properly handle bare (without =xxx)
+ "--with-regex" option.
+
+Sun Jul 5 21:02:16 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta15 released
+
+ * sed/utils.c(ck_fflush), sed/utils.h, sed/execute.c(output_line):
+ add and use new ck_fflush() function.
+
+Sun Jul 5 15:23:47 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(bad_prog): add more detail to error
+ messages about -e strings.
+
+Sun Jul 5 14:29:45 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(mark_subst_opts), sed/execute.c(do_subst):
+ Define better semantics for interaction of the `g' flag
+ with a numeric flag to the s/// command. It used to
+ be that the `g' command siezed control; now the first
+ (number-1) matches are skipped and then `g' gets control
+ after that. (It is not clear whether this is a feature
+ sneaking in during late beta, or a bug fix; the changes
+ involved were trivial, so I decided to treat it as a bug
+ fix.)
+
+ * configure.in, testsuite/version.good: update to beta15.
+
+Sat Jul 4 09:54:45 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta14 released
+
+ * sed/basicdefs.h, sed/compile.c, sed/execute.c:
+ per report by "Kaveh R. Ghazi" <ghazi@caip.rutgers.edu>,
+ copied the ISXXX macros from lib/regex.c so that
+ silly machines which require isascii() to be true
+ before the other isXXX() macros are valid will
+ still work.
+
+ * configure.in, testsuite/version.good: update to beta14.
+
+Thu Jul 2 23:46:13 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta13 released
+
+ * configure.in, acconfig.h: set USE_REGEX_GNU_H symbol if we
+ are going to be using lib/regex.c.
+
+ * lib/Makefile.am, lib/regex.h, lib/regex-gnu.h, lib/regex.c:
+ rename lib/regex.h to lib/regex-gnu.h, so that those who
+ choose to use a different regex implementation will not
+ pick-up lib/regex.h when doing "#include <regex.h>".
+
+ * sed/regex-sed.h, sed/Makefile.am, sed/compile.c, sed/execute.c,
+ sed/sed.c: create sed/regex-sed.h which acts as a switch
+ to choose either lib/regex.h or the user-supplied <regex.h>,
+ depending on the value passed to configure's --with-regex=
+ option.
+
+Thu Jul 2 17:22:31 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: if an alternative --with-regex= is given,
+ do an AC_CHECK_FUNCS(regnexec regexec) to ensure that
+ at least one of these functions is available. Also,
+ parallel changes for the default case.
+
+ * sed/execute.c, acconfig.h: retire use of the WITH_REGNEXEC
+ test macro in favor of HAVE_REGNEXEC test macro created
+ by above change.
+
+ * djgpp/config.bat: Play games to handle "install-sh",
+ DOS filename restrictions, GNU makefile default rules,
+ and getting a correct run of "configure" (contributed
+ by Eli Zaretskii <eliz@is.elta.co.il>).
+
+ * djgpp/Makefile.am, testsuite/Makefile.am, testsuite/Makefile.in,
+ Makefile.am, configure.in: Various automake targets
+ (such as distcheck) failed with old configuration.
+ The simplest solution was to just add these .am
+ files. (The testsuite/Makefile.in was just renamed to
+ testsuite/Makefile.am, then various redundant defines and
+ targets were deleted.) (Reported by Erick Branderhorst
+ <Erick.Branderhorst@asml.nl>.)
+
+ * testsuite/dc.good, testsuite/dc.inp: per suggestion from
+ Greg Ubben <gsu@romulus.ncsc.mil>, use base 16 output to
+ exercise even more of the dc.sed script.
+
+ * configure.in, testsuite/version.good: update to beta13.
+
+Sun Jun 28 16:21:02 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta12 released
+
+ * doc/sed.texi: Avoid mixing @code and @samp markups together:
+ they look ugly in Info. Use @url and @email instead of @example.
+ Add indexes. (Basis of changes contributed by Eli Zaretskii.)
+
+ * djgpp/*, Makefile.am: add support for the DJGPP compiler,
+ contributed by Eli Zaretskii <eliz@is.elta.co.il>.
+
+ * dc.sed, testsuite/Makefile.in, testsuite/dc.inp, testsuite/dc.good:
+ added this remarkable script, written and contributed
+ by Greg Ubben <gsu@romulus.ncsc.mil>, both as a work of
+ art for general admiration, and also for use in regression
+ testing.
+
+ * configure.in, lib/Makefile.am: add --with-regex=regexlib
+ option, which overrides the use of lib/regex.c.
+
+ * configure.in, testsuite/version.good: update to beta12.
+
+Fri Jun 12 16:41:48 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta11 released
+
+ * sed/compile.c: add module-static variables first_script
+ (for #n change below) and pending_text (for a/c/i change
+ below).
+
+ * sed/compile.c(compile_file), sed/compile.c(compile_program):
+ Instead of having #n trigger the -n option in *any file*,
+ have #n trigger the -n option only if they are the first
+ two bytes of the first script or script-file.
+
+ * sed/compile.c(compile_string), sed/compile.c(compile_file):
+ clear the first_script variable at end of these functions.
+
+ * sed/sed.h: tease out the struct text_buf declaration from
+ struct sed_cmd, so that a pointer to such can be passed
+ to new sed/compile.c(read_text) function.
+
+ * sed/compile.c(compile_program), sed/compile.c(read_text):
+ Tease out handling of text to a/c/i commands to new
+ read_text() function. Handle (via aid of pending_text
+ variable) texts which span more than one script/script-file
+ option. In particular, restore the ability to have this
+ work: sed -e '1i\' -e 'foo'
+
+ * sed/compile.c(check_final_program): close off any dangling
+ pending_text allocation.
+
+Thu Jun 11 11:17:46 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/execute.c(do_subst): fixed two bugs: s/ */X/g was failing
+ to match the final empty string after the end of the pattern
+ space; and /^foo$/s/o/x/3p was printing, despite the failure
+ to do a substition.
+
+Fri Jun 5 04:40:24 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: change the AC_ARG_WITH(regnexec, ...)
+ to be the more appropriate AC_ARG_ENABLE(regnexec, ...).
+
+ * configure.in, testsuite/version.good: update to beta11.
+
+Fri Jun 5 00:54:25 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta10 released
+
+ * sed/execute.c: forgot to P_() the prototype and
+ old-style the declaration for bootstrap_memchr()!
+
+Thu Jun 4 18:42:30 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(snarf_char_class): added code to
+ recognize \n or \<newline> sequence within a
+ char-class as the newline character.
+
+Tue Jun 2 11:56:02 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: added check for <sys/types.h> and
+ a AC_ARG_WITH(regnexec,...) check, to simplify use
+ of other regex libraries which have regexec() but
+ not regnexec(), with the corresponding loss of
+ functionality (regexps will not work right against
+ input lines which contain NULs).
+
+ * sed/execute.c: add nul_append() function, a #define
+ for a regnexec() -> regexec() macro (conditional on
+ the lack of the WITH_REGNEXEC symbol), and a couple
+ of calls to nul_append() (in match_an_address_p()
+ and do_subst()) to permit the use of the POSIX standard
+ regexec() function call instead of the suggested
+ regnexec() call.
+
+ * sed/compile.c, sed/execute.c, sed/sed.c: check for
+ <sys/types.h> and include it (before "regex.h") if
+ available. This makes it simpler to use the system's
+ regex library instead of the one in lib/regex.c, should
+ that be desired.
+
+Tue Jun 2 08:41:05 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/basicdefs.h: define VCAST macros to allow sed to
+ compile on systems which predate the definition
+ of "void *", and yet still get feedback about
+ stupid programming errors from systems which *do*
+ know about "void *"s. Also define MALLOC, REALLOC,
+ MEMDUP, and FREE macros to keep under control the
+ degree of code ugliness which would otherwise be
+ introduced in making use of the VCAST macro.
+
+ * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c:
+ pervasively use the new VCAST, MALLOC, REALLOC, MEMDUP,
+ and FREE macros wherever appropriate.
+
+ * sed/utils.c, sed/utils.h: correct type of first arguments
+ to ck_fread() and ck_fwrite() to be [const] VOID *.
+
+ * sed/basicdefs.h, sed/execute.c: protect against
+ the rumored systems which stupidly #define __STDC__ 0.
+
+ * testsuite/help.good, testsuite/Makefile.in: make
+ the ``help'' test insensitive to the spelling of
+ the executable's name. Also, enhanced `make clean'
+ target.
+
+ * doc/sed.texi, doc/sed.1: correct documentation of `q'
+ command; fix typos.
+
+ * configure, testsuite/version.good: update to beta10.
+
+Sat May 30 17:28:00 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta9 released
+
+ * Makefile.am: make testsuite a normal SUBDIR.
+
+ * configure.in: discontinue using AC_ISC_POSIX --
+ check for -lcposix library instead; added
+ testsuite/Makefile to AC_OUTPUT list.
+
+ * lib/memmove.c(memmove): fixed wrong sense used
+ for HAVE_BCOPY test.
+
+ * sed/execute.c: checked more specifically for a version
+ of gcc which supports __attribute__ (i.e., >= 2.7).
+
+ * testsuite/*: renamed files to fit 14 char limit.
+
+ * testsuite/Makefile, testsuite/Makefile.in: Makefile
+ renamed to Makefile.in and then modified so that
+ "make -j check" from top directory will work.
+
+ * testsuite/subwrite.sed, testsuite/writeout.sed: changed
+ file name of the "w" command to be consistent with the
+ new naming used in testsuite/Makefile.in.
+
+ * doc/sed.1, doc/sed.texi: fixed some typos, formatting
+ glitches, and poor wordings.
+
+Sat May 30 04:02:29 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: specify that config.h is to be derived
+ from config_h.in in order to avoid the braindead
+ DOS filesystem limitations.
+
+Fri May 29 21:56:30 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(compile_address), doc/sed.texi: gave
+ a better definition to the meaning of N~0 address
+ forms -- N~M addresses now mean that lines match
+ when there exists a non-negative x such that
+ lineno == N+x*M.
+
+Fri May 29 12:07:38 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(compile_address),
+ sed/execute.c(match_an_address_p): update semantics of
+ N~M address form: now N is the first line which will
+ match and M is the step between succeeding matches.
+ If N<M this works out to the same as before, but the
+ new behavior for N>=M seems more useful.
+
+ * doc/sed.1, doc/sed.texi: update documentation of N~M
+ address form; added "Other Resources" node to sed.texi;
+ minor formatting changes to some items in sed.1 with
+ an eye to improving clarity.
+
+ * configure.in, testsuite/version.good: update to beta9.
+
+Sat May 23 20:04:31 HST 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta8 released
+
+ * sed/compile.c(compile_regex): forgot to make last_re be
+ a *copy* of the buffered text in today's earlier fix.
+
+ * sed/execute.c(read_file_line): EOF check was wrong --
+ it forgot to allow for the possibility that we were
+ appending to the end of the ``line'' (instead of merely
+ reading a fresh line).
+
+Sat May 23 18:07:18 HST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/compile.c(compile_regex): don't track compiled version
+ of regex -- the modifiers may change. Track the regex
+ source instead. (For "last regex" (aka //) notation.)
+
+ * configure.in, testsuite/version.good: update to beta8.
+
+Sat May 23 16:07:09 HST 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta7 released
+
+ * sed/execute.c: #undef'd EXPERIMENTAL_DASH_N_OPTIMIZATION
+ because its code is buggy.
+
+Tue May 19 17:03:52 HST 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c: label rx library code as such with #ifdefs
+ (instead of just #if 0).
+
+ * sed/compile.c(compile_program): make incremental
+ improvement to the "Unknown command" error message.
+
+Sat May 16 23:16:26 HST 1998 Ken Pizzini <ken@gnu.org>
+
+ * testsuite/Makefile: simplify: get rid of automatic run
+ against system's sed; don't time by default; allow for
+ alternative comparison command.
+
+ * configure.in, testsuite/version.good: update to beta7.
+
+Wed May 13 21:44:28 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta6 released
+
+ * lib/Makefile.am: fix spelling of libsed_a_LIBADD in
+ libsed_a_DEPENDENCIES.
+
+ * configure.in, testsuite/version.good: update to beta6.
+
+Wed May 13 14:38:08 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta5 released
+
+ * sed/execute.c(do_subst): added not_bol_p variable to track when
+ we have iterated past the beginning of the pattern.
+ [Thanks to Jim Meyering <meyering@ascend.com> for the bug report.]
+
+Wed May 13 13:54:04 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/execute.c(bootstrap_memchr): new function. When
+ bootstrapping we don't know if we are on a 64-bit machine,
+ so lib/memchr.c breaks. Supply this (slow) implementation
+ just to get us bootstrapped.
+
+ * bootstrap.sh: add a #define BOOTSTRAP symbol; add -I.
+ for emphasis for the compiles in sed/; be explicit
+ about what files we're bothering to compile.
+
+ * configure.in, testsuite/version.good: update version
+ to beta5.
+
+Wed May 13 06:39:06 PDT 1998 Ken Pizzini <ken@gnu.org>

+ * rename writeout.good? to wrtout?.good and subwrite.good? to
+ subwrt?.good to comply with DOS 8+3 file name restrictions.
+ [Eli Zaretskii <eliz@is.elta.co.il> suggested this to
+ simplify DJGPP ports, and it was easy.]
+
+ * testsuite/Makefile: reflect above name changes.
+
+Wed May 12 21:09:32 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/sed.c(usage): fix non-portable omission of \n\ at end of
+ lines within long string.
+
+ * sed/sed.c(main): remove spurious argument to fprintf() in the
+ 'V'ersion output.
+
+ * sed/execute.c(line_append): embed newline between the two
+ text fragments unconditionally.
+
+ * sed/execute.c(do_subst): change structure assignment to memcpy()

+
+ * README.bootstrap: suggest using -w option.
+
+Tue May 12 10:02:37 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: use AC_REPLACE_FUNCS where appropriate.
+
+ * lib/Makefile.am: updated to reflect AC_REPLACE_FUNCS change in
+ configure.in.
+
+ * lib/memchr.c lib/memcmp.c: revert to standard GNU versions.
+
+ * lib/alloca.c: added this missing file.

+
+Sat May 9 22:35:45 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta2 released
+
+ * sed/sed.c: add #include <sys/types.h> in HAVE_MMAP
+ block (needed on some machines).
+
+ * lib/memmove.c: #include <memory.h>, if HAVE_MEMORY_H.
+
+Sat May 9 21:29:00 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in: remove dangling references to rx library;
+ added HEADER and FUNC checks for items used by source in
+ lib/.
+
+ * lib/ansidecl.h, lib/memcopy.h, lib/pagecopy.h, lib/string.h
+ lib/memcpy.c, lib/memmove.c: deletes these files. There
+ are still pieces of glibc missing to support these, and
+ it isn't worth the headache right now.
+
+ * lib/memmove.c: de novo, simpler version. Uses bcopy()
+ if available, and slow-but-simple code if not.
+
+ * lib/Makefile.am: remove references to deleted files.
+ Added forgotten reference to memcpy.c. Re-ordered
+ SOURCE entries to reflect dependencies for systems
+ which lack ranlib.
+
+ * sed/basicdefs.h: updated to reflect above changes to lib/,
+ and experience with non-STDC compilers.
+
+ * lib/regex.c: made regerror() function publicly visible.
+
+ * lib/strerror.c: use old-style function declaration.
+
+ * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
+ sed/sed.h, sed/utils.h: ensure that private definitions of
+ some symbols do not cause problems when #include'ing system
+ headers (mainly by re-ordering the #include directives).
+ (This is particularly an issue for bootstrap.sh runs.)
+
+ * sed/execute.c (execute_program): use memcpy() instead of
+ structure assingment ('x' command), for portablility to
+ old compilers.
+
+ * sed/execute.c (slow_getline): use old-style function
+ declaration, with a P_ prototype.
+
+ * sed/sed.c: change the type of the fallback MAP_FAILED
+ definition to work on archaic systems. (Modern systems
+ should be defining it themselves, so the change from
+ void * shouldn't be a problem.)
+
+ * bootstrap.sh, README.bootstrap: actual testing of bootstrap
+ code revealed that I was too optimistic. Redesigned and
+ replaced implementation.
+
+ * testsuite/Makefile: ignore errors from reference-implementation
+ seds that aren't up to snuff.
+
+ * testsuite/help.good, testsuite/version.good: update to
+ current version's output.
+
+Fri May 8 15:08:28 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ *** Version 3.01-beta1 released
+
+ * sed/sed.c (main, usage): once again tweak the --help and
+ --version output to bettery comply with GNU coding standards.
+
+ * testsuite/help.good, testsuite/version.good: update to
+ reflect above change.
+
+ * doc/sed.texi: fix "Invoking" node's spelling to comply
+ with GNU standards.
+
+Fri May 8 11:43:10 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * doc/sed.1, doc/Makefile.am: wrote (very basic) man page.
+
+Thu May 7 20:40:21 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * lib/Makefile.am, lib/memmove.c, lib/memchr.c, lib/regex.c,
+ lib/memcpy.c, lib/regex.h, lib/memcopy.h, lib/string.h,
+ lib/pagecopy.h, lib/ansidecl.h: grab yet-another-version
+ from gnu.org for baseline and/or edit copyright boilerplate
+ using official lgpl2gpl.sed script. Take care not to
+ loose regnexec() interface or special conditional-compilation
+ code.
+
+Wed May 6 23:35:12 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * lib/regex.c, lib/regex.h: take from grep-2.1 distribution,
+ then trivially added the regnexec() interface.
+
+ * sed/sed.c, sed/compile.c, sed/execute.c: made modifications
+ to work with regex instead of rx.
+
+ * rx/*: deleted directory; the code is just too slow.
+ I think it will be easier to extend regex to fully
+ support POSIX.2 than to tune rx to be reasonable.
+ Even if this supposition is wrong, I'd rather make
+ the 3.01 release with the slightly deficient regex.
+
+ * Makefile.am lib/Makefile.am, sed/Makefile.am: made changes
+ related to the substitution of regex for rx.
+
+ * lib/Makefile.am, sed/Makefile.am: since regex is not a
+ ``compatability'' module, changed name of library to
+ ``libsed.a''.
+
+ * lib/memchr.c, lib/memcpy.c, lib/memmove.c: add conditional
+ compilation code to leave zero-sized .o file if system
+ already supports the implemented function.
+
+ * testsuite/help.good, testsuite/version.good: brought
+ up-to-date (once again).
+
+ * NEWS, ANNOUNCE: changes to reflect this batch of changes.
+
+Wed May 6 18:40:47 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/execute.c: discovered awful bug in '}' handling:
+ it could read past the end of vec (because `n' was
+ being decremented below zero)! Needed to "continue"
+ instead of "break".
+
+Tue May 5 14:34:38 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * doc/sed.texi, doc/version.texi: wrote some rudimentary
+ texinfo documentation.
+
+ * ANNOUNCE, NEWS, README, README.rx, Makefile.am:
+ more updates for the upcoming beta-release.
+
+ * sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
+ sed/sed.h, lib/strerror.c: update copyright notice text.
+
+Fri May 1 15:41:37 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed/execute.c (match_an_address_p, match_address_p): if
+ the second element of an address range is a line number,
+ and that line number is *less than* (or equal to) the
+ current line number, we only match the one line (per
+ POSIX.2, section 4.55.7.1). [Bug discovered as reported
+ in the seders mailing list FAQ.]
+
+ * AUTHORS, NEWS, acconfig.h, configure.in, doc/Makefile.am,
+ lib/Makefile.am, sed/Makefile.am, lib/README,
+ testsuite/help.good, testsuite/version.good:
+ Updated in anticipation of the 3.01-beta1 release.
+ Reorganized development source tree to make creation
+ of a distribution simpler. Most notable changes were
+ to the various Makefile.am files and configure.in, but
+ some minor edits (such as deleting or changing #include
+ directives) have been made in many other source files.
+
+ * bootstrap.sh, README.bootstrap: created a mechanism for
+ creating sed on a system which lacks a working sed.
+
+Thu Apr 16 23:52:11 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed.h, sed.c, execute.c, compile.c: did a spell-check on
+ the comments; fixed several typos.
+
+Thu Apr 16 13:43:01 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c (do_subst): fixed bug where the "replaced" flag
+ was being set to one inappropriately when at least one
+ but fewer than sub->numb matches of the regexp were found.
+ (Thanks to Simon Taylor <staylor@hermes.iaccess.com.au>
+ for the bug report.)
+
+Wed Apr 15 11:35:31 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed.h, sed.c, compile.c, execute.c: having a concern that
+ a cast was being done inappropriately, and realizing that
+ there is no quick way to locate all casts in a program, I
+ went through and marked all casts with a simple macro.
+ Now it is a simple matter to locate the casts, and it is
+ also a simple matter to turn of casts for a lint session
+ (if it should be desired).
+
+Wed Apr 15 10:29:21 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * compile.c, sed.c: redo compile phase so that brace
+ expressions can be spread across multiple files.
+ For example:
+ printf '{' >a; printf 'l;d' >b; printf '}' >c
+ sed -f a -f b -f c foo
+ will now compile (and work), instead of complaining
+ about an unmatched '{'. The mess created in compile.c
+ allowed a little simplification to the command-line
+ processing of "-e" options in sed.c.
+
+ sed.h: added (opaque) err_info member to struct vector;
+ added comments to the members of struct vector.
+
+Wed Apr 14 23:50:50 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * sed.h, sed.c, compile.c, execute.c: added types countT and
+ flagT in order to clarify what various "int"s were doing.
+ Also makes it easy to change the type used for counts
+ (for example, to "unsigned long long") if desired, although
+ there are still some gotchas (such as the printf() format
+ for the '=' command).
+
+Tue Apr 14 17:34:54 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c (execute_program, process_files, count_branches,
+ shrink_program): Added a first attempt at program optimization.
+ We now can quit early if we are running with the "-n"
+ and all of the commands are known to be valid only for
+ lines less than the current line. Thus the "sed" in
+ "foo | sed -n 1,2p" will print read three lines, printint
+ the first two, and then quit, regardless of how much longer
+ "foo" might run or output. This optimization does not buy
+ much in most cases (it sometimes even costs a little),
+ but when it does help it can help big. The code is
+ all conditionally compiled based on the
+ EXPERIMENTAL_DASH_N_OPTIMIZATION symbol being #defined,
+ so it can be easily omitted if it causes problems.
+
+Tue Apr 14 12:25:06 PDT 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c (test_dollar_EOF, last_file_with_data_p):
+ test_dollar_EOF() was incorrectly returning a false (0)
+ when there were unprocessed files, none of which had any
+ data (either unopenable or zero-length). Created
+ last_file_with_data_p() to detect this situation, and
+ modified test_dollar_EOF() to make use of it.
+
+Thu Apr 2 23:02:18 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * compile.c (match_slash): match_slash() did not handle
+ [.coll.], [=equiv=], and [:class:] sequences within a
+ character class. Added snarf_char_class() [which is a
+ remote derivative of parse_char_class() from GNU ed-0.2]
+ to deal with the details, and altered match_slash()
+ to make use of it. Also created the trivial
+ add_then_next() to avoid clutter in snarf_char_class().
+
+Thu Apr 2 20:34:42 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c, sed.c, sed.h: There was a severe bug in
+ how the code handled "sed 5n a b" when "a" consists
+ of exactly five lines -- it behaved like "sed 5q a b"!
+
+ Rearranged where files get opened -- large scale
+ changes primarily involving main(), process_files(),
+ and read_pattern_space(), but also touching on several
+ other parts of execute.c. The read_pattern_space()
+ function became unwieldly and parts were split into
+ open_next_file(), closedown(), read_always_fail(),
+ read_mem_line(), and read_file_line(). The
+ at_end_of_file_p() function became obsolete and was
+ eliminated; test_dollar_EOF_p() was updated. A few
+ global and module-static variables were elminated, and
+ "struct line" was extended; comments were added to the
+ "struct line" declartation to document some important
+ dependencies in it.
+
+ I undertook the reorganization with dread, but I
+ feel that the new organization is an improvement
+ well beyond just fixing the bug that inspired it.
+
+Thu Apr 2 01:16:25 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * execute.c (read_file_line, slow_getline): the fread()
+ buffering code gives insufficient feedback to a user
+ running sed with a tty input device, so I created
+ slow_getline() for reading from a tty device.
+ Additionally, EOF detection has been made a little more
+ sensitive to avoid requiring multiple EOFs to be entered
+ from a tty.
+
+ * configure.in: added isatty() check.
+
+Wed Apr 1 11:04:30 PST 1998 Ken Pizzini <ken@gnu.org>
+
+ * configure.in (CPPFLAGS, LDFLAGS, LIBS):
+ Set to appropriate values if large file support needs
+ explicit enabling. Code fragment taken from a 1997-10-25
+ patch to gawk by Paul Eggert <eggert@twinsun.com>
+
+Thu Aug 14 17:43:27 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * utils.c (ck_fclose): modified to ignore NULL parameter.
+
+Thu Aug 14 12:08:45 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * execute.c: tweaked execute_program() to eliminate
+ gratuitous "goto" usage.
+
+Thu Aug 14 11:30:04 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * compile.c: added case-insensitive modifier ('I') to
+ address and s/// regexps. The s/// case also accepts
+ the more popular 'i' modifier. (The address regexp
+ cannot use 'i' as a modifier, as that conflicts with
+ the use of the 'i'nsert command.)
+
+Thu Aug 14 09:29:06 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * compile.c: abstracted out match_slash() from the s///, y///,
+ and address-regexp special-case codes.
+
+ * execute.c: made dump_append_queue() use ck_fread() instead
+ of hand-rolled error checking.
+
+Mon Jul 28 10:50:41 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * sed.c, sed.h, execute.c: POSIX.2, section 4.55.7, says that
+ a newline must end *every* output line. But I think that
+ it is useful (when seding a binary file) to omit a trailing
+ newline if the input lacks one. Thus the addition of
+ POSIXLY_CORRECT behavior.
+
+ * execute.c: however, when seding multiple files my feeling
+ is that it makes sense to have each file but the last
+ behave as-if it ended in a newline. Modified read_pattern_space()
+ accordingly.
+
+ * utils.c: realized that add1_buffer(), for performance reasons,
+ shouldn't be calling memcpy() (indirectly via add_buffer()),
+ so rewrote it.
+
+Sat Jul 26 23:08:28 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * execute.c: attempted to make read_pattern_space more
+ efficient for the the non-mmap() case.
+
+ * utils.c, utils.h, execute.c: new function ck_fread()
+ created and used.
+
+Sat Jul 26 20:22:14 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * execute.c, compile.c, sed.c: abstracted the mmap()
+ interface into map_file()/unmap_file() [sed.c], and
+ changed the ad-hoc code in compile_file() [compile.c]
+ and process_file() [execute.c] to make use of the new
+ interface.
+
+Sat Jul 26 19:45:46 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * execute.c, compile.c, configure.in: Check to see if mmap()
+ is available; if so make use of it on regular files.
+
+ * compile.c: compile_file() now closes the input file
+ when it is through!
+
+Sun Jul 20 23:57:02 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * compile.c: modified parsing to permit whitespace in more
+ places where it makes sense;
+ added backslash escaping to the y/// command, per POSIX.
+
+ * execute.c: Merged append_pattern_space() into read_pattern_space();
+ moved body of 's' command to new function do_subst();
+ moved body of 'l' command to new function do_list();
+ changed output of 'l' command to conform to POSIX.2;
+ made line handling conform to POSIX; added output_line() function;
+ redesigned append-space algorithm; added append_queue structure and
+ the next_append_slot() and dump_append_queue() functions.
+
+ * sed.h: moved the definition of what is now struct subst
+ outside of the definition of struct sed_cmd.
+
+Sat Jul 19 16:29:09 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * sed.c, execute.c, sed.h, Makefile.am: Separated out the
+ pieces dealing with executing the program from the top-level
+ parameter parsing and control.
+
+Sat Jul 19 01:16:35 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * sed.c, compile.c, sed.h, Makefile.am: separate out the
+ pieces dealing with compiling the program from the pieces
+ dealing with interpreting the result.
+
+ * compile.c: add functions in_nonblank() and in_integer(),
+ and change interface to compile_address() with an eye
+ to making code clearer.
+
+Fri Jul 18 13:35:50 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * utils.c: attempt at a quasi-unification of the
+ STDC and traditional C approaches to panic().
+
+ * sed.c: eliminate some gratuitous bit twiddling.
+ (Using flag bits can be a useful technique, but
+ this code is cleaner without them.)
+
+ * sed.c: place mutually exclusive members of struct addr
+ within a union, mainly to document the exclusivity;
+ eliminate unused structure members from struct fp_list;
+ eliminate unnecessary module-global variables;
+ remove some #if 0 code that is too odd to keep;
+ allegedly simplified the 'l' case of execute_program();
+ allegedly simplified inchar();
+ localized some static variables;
+ renamed some variables to better document their purpose;
+ removed some goto-s rendered obsolete by other changes.
+
+Thu Jul 17 15:30:44 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * utils.c, utils.h, sed.c: added and made use of
+ ck_free() function.
+
+ * utils.c, utils.h, sed.c: changed all the *_buffer()
+ functions to take/return an incomplete type
+ "struct buffer *" instead of using VOID *.
+
+ * utils.c, utils.h, sed.c: renamed "finish_buffer()"
+ to "free_buffer()", on the premise that the new
+ name better describes the function's purpose.
+
+Wed Jul 16 13:52:14 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * utils.c, utils.h, sed.c: added and made use of
+ ck_memdup() function.
+
+ * sed.c: protected a call to add1_buffer() in
+ compile_program() which could have tried to
+ push an EOF if a a/i/c command ended with
+ a '\', EOF sequence.
+
+ * utils.c: added sanity check to add1_buffer() so that
+ EOF will not be added to the buffer.
+
+Wed Jul 16 03:56:26 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * configure.in, compat.h, compat.c: added memchr.
+
+ * sed.c: got rid of arbitrary NUM_FPS limit;
+ made global functions and variables "static" where appropriate;
+ make various cosmetic changes, hopefully improving readability;
+ simplified some redundant predicates;
+ simplified some code, but nothing fundamental (yet?).
+
+Wed Jul 16 00:24:54 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * alloca.c, getopt.c, getopt.h, getopt1.c: updated from
+ versions in textutils-1.22.
+
+ * Makefile.in, Makefile.am, configure.in: put in automake support.
+
+ * basicdefs.h, compat.h, compat.c [, sed.c, utils.c]: took out
+ some very ugly compatibility #ifdefs and packaged into one
+ place.
+
+ * sed.c, utils.c: some gratuitous formatting changes.
+
+ * utils.c: changed datatype of utils_id_s in order to
+ eliminate arbitrary array size.
+
+Sun Jul 13 17:00:26 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * sed.c, utils.c, utils.h: de-linting oriented cleanup.
+
+Sun Jul 13 00:46:48 PDT 1997 Ken Pizzini <ken@gnu.org>
+
+ * sed.c: fixed bug which caused SEGV for files missing a
+ final newline. Corrected calls to regnexec to pass the
+ proper parameters, in the proper order.
+
+Sat Dec 30 20:16:59 1995 Tom Lord <lord@beehive>
+
+ *** Version 3.00 released

+
+ *** Version 2.05 released
+
+ * sed.c (compile_address): Recognize numeric addresses.
+ Fixes typo made during installation of "~" feature.
+
+Sat Apr 30 17:17:38 1994 Tom Lord (lord@x1.cygnus.com)
+
+ *** Version 2.04 released
+
+ * sed.c: applied a patch from
+ From: kap1@tao.cpe.uchicago.edu (Dietrich Kappe)
+
+ Dietrich writes:
+
+ As my contribution to the creeping feature creature in sed,
+ here is a new type of address. The address has form n~m,
+ which means "the line number is equal to n modulo m." The
+ modifications to sed are trivial, and the general
+ usefulness of this address should be obvious. If m is 0 or
+ missing, 1 is used in its place (could be a bug or a
+ feature :-).
+
+Sat Apr 30 17:17:38 1994 Tom Lord (lord@x1.cygnus.com)
+
+ * rx.c (solve_destination): protect `solution' more carefully.
+ This is a cleanup of a patch from Kevin Buettner
+ (kev@cujo.geg.mot.com).
+
+Sat Apr 30 17:17:38 1994 Tom Lord (lord@x1.cygnus.com)
+
+ * rx.c: make translation tables unsigned chars
+
+ * sed.c (main): Compile accumulated -e commands as

+ the commands are executed in the right order.
+
+Mon Oct 25 14:41:47 1993 Tom Lord (lord@rtl.cygnus.com)
+
+ * sed.c (execute_program): 'w' flushes the buffer after it
+ writes -- diagnosed by doug@research.att.com. 'r' and 'w' to
+ the same file is now supported -- hopefully even in a way that
+ satisfies Posix (it now behaves differently from some
+ /bin/sed's and the spec is hard to read so i'm not sure).
+
+ Also, 'r' of a non-existent file is now permitted.
+
+Mon Oct 11 21:06:10 1993 Tom Lord (lord@cygnus.com)

+
+Thu May 27 11:13:03 1993 Tom Lord (lord@unix3.andrew.cmu.edu)
+
+ * sed.c (execute_program, match_addr): caught more cases
+ that need to be sensitive to a missing \n at EOF.
+
+Fri May 21 00:39:22 1993 Tom Lord (lord@unix8.andrew.cmu.edu)
+
+ * sed.c (execute_program): apply gaumondp's patch
+ to fix '\xabcxs/foo/bar/'.
+
+ * sed.c (execute_program):
+ If a second address is a regexp, never match it on the
+ same line as the first address.
+
+ * sed.c (compile_regexp):
+ Numeric ranges x,y s.t. y < x are now treated as x,x.
+ There was a bug in that they were being handled like x,x+1.
+
+ * sed.c (execute_program, read_pattern_space,
+ append_pattern_space) don't add newlines to lines
+ that don't have them.
+
+Wed May 19 13:34:45 1993 Tom Lord (lord@unix9.andrew.cmu.edu)

+
+ * alloca.c: new (standard) file
+
+ * configure.in: AC_CONSTified
+
+ * sed.c (compile_program): properly diagnose the error of
+ a missing command (e.g. sed /x/). (thanks gaumondp)
+
+ * sed.c (compile_regexp): handle character classes correctly.
+ Thanks gaumondp@ERE.UMontreal.CA
+ and schwab@issan.informatik.uni-dortmund.de.
+
+Thu May 6 12:37:18 1993 Tom Lord (lord@unix10.andrew.cmu.edu)
+
+ * sed.c (compile_filename, execute_program): don't use
+ `access' or `/dev/null'.
+
+ * sed.c (execute_program): 'N' at EOF should delete the pat buf.
+
+ * sed.c (compile_filename): truncate, don't append files
+ being openned for `w' or `s///w'
+
+ * sed.c (execute_program): -n switch shouldn't effect `i' or `c'.
+
+ * sed.c (compile_program): don't compile unescaped newlines
+ into the substitution string of an `s' command (they are an error).
+
+ * sed.c (compile_regex): correctly skip over character
+ sets that contain `]'.
+
+ * sed.c (execute_program): patch from gaumondp
+ Correctly handle empty-string matches in the case of an `s'
+ command with a repeat count.
+
+ * sed.c (compile_program): patch from gaumondp@ere.UMontreal.ca.
+ Don't consume characters after the label of a `b', `t' or `:' command.
+
+ * sed.c (compile_program): unmatched open braces are an error.
+
+ * sed.c (compile_file): when consuming an initial comment,
+ count lines correctly.
+
+Wed Nov 18 02:10:58 1992 Tom Lord (lord@unix2.andrew.cmu.edu)
+
+ * sed.c (execute_program): Made s///p print even if -n was
+ specified.
+
+ * sed.c (compile_string): Changed the type of this function to
+ fix a compile warning.
+
+Wed Nov 4 17:15:34 1992 Tom Lord (lord@unix7.andrew.cmu.edu)
+
+ * sed.c (main): Initialize the hold area to contain "\n"
+ instead of "". In execute_program, all lines are expected
+ to be newline terminated. Also, if H is the first command
+ in the script, the result is a pattern buffer that begins
+ with a blank line. Thanks to pinard@iro.umontreal.ca
+ (Francois Pinard) for pointing out this and many other bugs.
+
+ * sed.c (execute_program): Fixed a case of `D' command.
+ Thanks Chris Weber <weber@bucknell.edu>
+

+ Thanks Andrew Herbert <andrew@werple.apana.org.au>
+

+ Thanks "J.T. Conklin" <jtc@gain.com>
+
+ * sed.c: made prog_cur, prog_start, and prog_end unsigned so
+ that users could write `sed -e s/ÿ/foo/g'.
+

+ that karl@gnu fixed some regexp bugs that were plaguing sed.
+
+Thu Apr 30 13:02:21 1992 Tom Lord (lord at unix3.andrew.cmu.edu)
+
+ * sed.c (compile_program, execute_program)
+ subprograms are now compiled with an explicit continuation ;)
+ return_v and return_i in struct vector. execute_program
+ no longer recurses to execute subprograms (case '{') and now
+ understands a return instruction (case '{').
+
+Tue Apr 28 17:13:04 1992 Tom Lord (lord at unix7.andrew.cmu.edu)
+
+ * sed.c (compile_address) added \?regexp? syntax for addresses.
+
+ * sed.c (main) added {} intervals to the obscure regexp
+ syntax.
+
+ * sed.c (compile_program) after calling compile_address,
+ normalize numeric addresses (make a2.addr_number > a1.addr_number).
+ This is necessary because line numbers must match exactly,
+ but sed does not try to match a2 until after a1 has matched,
+ yet a1,a2 where a2 <= a1 is defined to be equivelent to
+ a1,a1+1
+
+Sat Feb 29 10:55:54 1992 David J. MacKenzie (djm@nutrimat)
+
+ * sed.c (usage): Document long options as starting with `--'.
+
+Mon Dec 9 23:56:40 1991 David J. MacKenzie (djm at wookumz.gnu.ai.mit.edu)
+
+ * sed.c: Include sys/types.h, for new regex.h.
+
+Tue Nov 5 02:16:01 1991 David J. MacKenzie (djm at wookumz.gnu.ai.mit.edu)
+
+ * utils.c: Change NO_VFPRINTF to VPRINTF_MISSING, for
+ compatibility with autoconf.
+
+Mon Sep 2 22:02:40 1991 David J. MacKenzie (djm at apple-gunkies)
+
+ * sed.c (compile_regex): Treat \ as a normal character when in
+ a char class.
+
+Thu Aug 8 00:15:33 1991 David J. MacKenzie (djm at bleen)
+
+ * Version 1.08.
+
+ * sed.c (compile_filename): If reading a file fails, read
+ /dev/null instead. It's what Unix and POSIX do, effectively.
+
+ * sed.c (compile_regex): The 'slash' character doesn't
+ terminate the regex if it's in a character class.
+
+ * sed.c (main): If given no args, or bad option, print usage
+ message.
+ (usage): New function.
+
+ * sed.c (execute_program): Amount written for 'P' command was
+ wrong. From stephend@ksr.com (Stephen Davis).
+
+Wed Aug 7 16:51:14 1991 David J. MacKenzie (djm at apple-gunkies)
+
+ * sed.c (append_pattern_space): Check for buffer full before
+ instead of after writing to buffer. Don't need to test for
+ EOF initially anymore, due to the next change.
+ (execute_program): For 'n' and 'N' commands, if eof is reached
+ in input, quit the script like Unix sed does.
+ Fix memory allocation problems for 'a' and 'r' commands.
+ (compile_program): Fix off by one error in processing comments.
+ All of the above are from Tapani Tarvainen, tarvaine@tukki.jyu.fi.
+
+ * sed.c (setup_jump): Use isblank instead of testing for ' '
+ or '\t', for POSIX locales.
+
+ * utils.c (ck_strdup): Renamed from strdup.
+ * sed.c: Change callers.
+
+ * sed.c, utils.c: Clean up declarations and includes to get
+ rid of compiler warnings.
+
+ * sed.c (main): Add long-named options. Don't complain if -n
+ is given twice.
+
+Fri Aug 2 12:33:16 1991 David J. MacKenzie (djm at apple-gunkies)
+
+ * configure: Support +srcdir arg. Create config.status and
+ remove it and Makefile if interrupted while creating them.
+ * Makefile.in: Change DESTDIR to prefix.
+
+Mon Jul 15 13:07:39 1991 David J. MacKenzie (djm at wookumz.gnu.ai.mit.edu)
+
+ * sed.c (main): Add -V option to print version number.
+ (USAGE): Mention -V.
+
+Mon Jul 8 01:42:22 1991 David J. MacKenzie (djm at geech.gnu.ai.mit.edu)
+
+ * sed.c: Define bcopy in terms of memcpy if STDC_HEADERS as
+ well as if USG.
+ (compile_filename): Don't glob filename (for 'r' and 'w'
+ commands). Unix sed doesn't do it and it's not very useful,
+ since it can only match 0 or 1 files.
+ (execute_program): Change '\a' to 007 since some compilers
+ don't recognize \a.
+ * utils.c: New file; code moved from sed.c.
+ * Replace Makefile with Makefile.in and configure.
+ Update README.

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
+Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script). Here is a another example:
+
+ /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+* hold-space is reset between different files in -i and -s modes.
+
+* multibyte processing fixed
+
+* the following GNU extensions are turned off by --posix: options [iImMsSxX]
+in the `s' command, address kinds `FIRST~STEP' and `ADDR1,+N' and `ADDR1,~N',
+line address 0, `e' or `z' commands, text between an `a' or `c' or `i'
+command and the following backslash, arguments to the `l' command.
+--posix disables all extensions to regular expressions.
+
+* fixed bug in 'i\' giving a segmentation violation if given alone.
+
+* much improved portability
+
+* much faster in UTF-8 locales
+
+* will correctly replace ACLs when using -i
+
+* will now accept NUL bytes for `.'
+
+----------------------------------------------------------------------------
+Sed 4.1.5
+
+* fix parsing of a negative character class not including a closed bracket,
+ like [^]] or [^]a-z].
+
+* fix parsing of [ inside an y command, like y/[/A/.
+
+* output the result of commands a, r, R when a q command is found.
+
+----------------------------------------------------------------------------
+Sed 4.1.4
+
+* \B correctly means "not on a word boundary" rather than "inside a word"
+
+* bugfixes for platform without internationalization
+
+* more thorough testing framework for tarballs (`make full-distcheck')
+
+----------------------------------------------------------------------------
+Sed 4.1.3
+
+* regex addresses do not use leftmost-longest matching. In other words,
+ /.\+/ only looks for a single character, and does not try to find as
+ many of them as possible like it used to do.
+
+* added a note to BUGS and the manual about changed interpretation
+ of `s|abc\|def||', and about localization issues.
+
+* fixed --disable-nls build problems on Solaris.
+
+* fixed `make check' in non-English locales.
+
+* `make check' tests the regex library by default if the included regex
+ is used (regex tests had to be enabled separately up to now).
+
+----------------------------------------------------------------------------
+Sed 4.1.2
+
+* fix bug in 'y' command in multi-byte character sets
+
+* fix severe bug in parsing of ranges with an embedded open bracket
+
+* fix off-by-one error when printing a "bad command" error
+
+----------------------------------------------------------------------------
+Sed 4.1.1
+
+* preserve permissions of in-place edited files
+
+* yield an error when running -i on terminals or other non regular files
+
+* do not interpret - as stdin when running in in-place editing mode
+
+* fix bug that prevented 's' command modifiers from working
+
+----------------------------------------------------------------------------
+Sed 4.1
+
+* // matches the last regular expression even in POSIXLY_CORRECT mode.
+
+* change the way we treat lines which are not terminated by a newline.
+Such lines are printed without the terminating newline (as before)
+but as soon as more text is sent to the same output stream, the
+missing newline is printed, so that the two lines don't concatenate.
+The behavior is now independent from POSIXLY_CORRECT because POSIX
+actually has undefined behavior in this case, and the new implementation
+arguably gives the ``least expected surprise''. Thanks to Stepan
+Kasal for the implementation.
+
+* documentation improvements, with updated references to the POSIX.2
+specification
+
+* error messages on I/O errors are better, and -i does not leave temporary
+files around (e.g. when running ``sed -i'' on a directory).
+
+* escapes are accepted in the y command (for example: y/o/\n/ transforms
+o's into newlines)
+
+* -i option tries to set the owner and group to the same as the input file
+
+* `L' command is deprecated and will be removed in sed 4.2.
+
+* line number addresses are processed differently -- this is supposedly
+conformant to POSIX and surely more idiot-proof. Line number addresses
+are not affected by jumping around them: they are activated and
+deactivated exactly where the script says, while previously
+ 5,8b
+ 1,5d
+would actually delete lines 1,2,3,4 and 9 (!).
+
+* multibyte characters are taken in consideration to compute the
+operands of s and y, provided you set LC_CTYPE correctly. They are
+also considered by \l, \L, \u, \U, \E.
+
+* [\n] matches either backslash or 'n' when POSIXLY_CORRECT.
+
+* new option --posix, disables all GNU extensions. POSIXLY_CORRECT only
+disables GNU extensions that violate the POSIX standard.
+
+* options -h and -V are not supported anymore, use --help and --version.
+
+* removed documentation for \s and \S which worked incorrectly
+
+* restored correct behavior for \w and \W: match [[:alnum:]_] and
+[^[:alnum:]_] (they used to match [[:alpha:]_] and [^[:alpha:]_]
+
+* the special address 0 can only be used in 0,/RE/ or 0~STEP addresses;
+other cases give an error (you are hindering portability for no reason
+if specifying 0,N and you are giving a dead command if specifying 0
+alone).
+
+* when a \ is used to escape the character that would terminate an operand
+of the s or y commands, the backslash is removed before the regex is
+compiled. This is left undefined by POSIX; this behavior makes `s+x\+++g'
+remove occurrences of `x+', consistently with `s/x\///g'. (However, if
+you enjoy yourself trying `s*x\***g', sed will use the `x*' regex, and you
+won't be able to pass down `x\*' while using * as the delimiter; ideas on
+how to simplify the parser in this respect, and/or gain more coherent
+semantics, are welcome).
+
+
+----------------------------------------------------------------------------
+Sed 4.0.9
+
+* 0 address behaves correctly in single-file (-i and -s) mode.
+
+* documentation improvements.
+
+* tested with many hosts and compilers.
+
+* updated regex matcher from upstream, with many bugfixes and speedups.
+
+* the `N' command's feature that is detailed in the BUGS file was disabled
+by the first change below in sed 4.0.8. The behavior has now been
+restored, and is only enabled if POSIXLY_CORRECT behavior is not
+requested.
+
+----------------------------------------------------------------------------
+Sed 4.0.8
+
+* fix `sed n' printing the last line twice.
+
+* fix incorrect error message for invalid character classes.
+
+* fix segmentation violation with repeated empty subexpressions.
+
+* fix incorrect parsing of ^ after escaped (.
+
+* more comprehensive test suite (and with many expected failures...)
+
+----------------------------------------------------------------------------
+Sed 4.0.7
+
+* VPATH builds working on non-glibc machines
+
+* fixed bug in s///Np: was printing even if less than N matches were
+found.
+
+* fixed infinite loop on s///N when LHS matched a null string and
+there were not enough matches in pattern space
+
+* behavior of s///N is consistent with s///g when the LHS can match
+a null string (and the infinite loop did not happen :-)
+
+* updated some translations
+
+----------------------------------------------------------------------------
+Sed 4.0.6
+
+* added parameter to `v' for the version of sed that is expected.
+
+* configure switch --without-included-regex to use the system regex matcher
+
+* fix for -i option under Cygwin
+
+----------------------------------------------------------------------------
+Sed 4.0.5
+
+* portability fixes
+
+* improvements to some error messages (e.g. y/abc/defg/ incorrectly said
+`excess characters after command' instead of `y arguments have different
+lengths')
+
+* `a', `i', `l', `L', `r' accept two addresses except in POSIXLY_CORRECT
+mode. Only `q' and `Q' do not accept two addresses in standard (GNU) mode.
+
+----------------------------------------------------------------------------
+Sed 4.0.4
+
+* documentation fixes
+
+* update regex matcher
+
+----------------------------------------------------------------------------
+Sed 4.0.3
+
+* fix packaging problem (two missing translation catalogs)
+
+----------------------------------------------------------------------------
+Sed 4.0.2
+
+* more translations
+
+* fix build problems (vpath builds and bootstrap builds)
+
+----------------------------------------------------------------------------
+Sed 4.0.1
+
+* Remove last vestiges of super-sed
+
+* man page automatically built
+
+* more translations provided
+
+* portability improvements
+
+----------------------------------------------------------------------------
+Sed 4.0
+
+* Update regex matcher
+
+----------------------------------------------------------------------------
+Sed 3.96
+
+* `y' command supports multibyte character sets
+
+* Update regex matcher
+
+----------------------------------------------------------------------------
+Sed 3.95
+
+* `R' command reads a single line from a file.
+
+* CR-LF pairs are always ignored under Windows, even if (under Cygwin)
+a disk is mounted as binary.
+
+* More attention to errors on stdout
+
+* New `W' command to write first line of pattern space to a file
+
+* Can customize line wrap width on single `l' commands
+
+* `L' command formats and reflows paragraphs like `fmt' does.
+
+* The test suite makefiles are better organized (this change is
+transparent however).
+
+* Compiles and bootstraps out-of-the-box under MinGW32 and Cygwin.
+
+* Optimizes cases when pattern space is truncated at its start or at
+its end by `D' or by a substitution command with an empty RHS.
+For example scripts like this,
+
+ seq 1 10000 | tr \\n \ | ./sed ':a; s/^[0-9][0-9]* //; ta'
+
+whose behavior was quadratic with previous versions of sed, have
+now linear behavior.
+
+* New command `e' to pipe the output of a command into the output
+of sed.
+
+* New option `e' to pass the output of the `s' command through the
+Bourne shell and get the result into pattern space.
+
+* Switched to obstacks in the parser -- less memory-related bugs
+(there were none AFAIK but you never know) and less memory usage.
+
+* New option -i, to support in-place editing a la Perl. Usually one
+had to use ed or, for more complex tasks, resort to Perl; this is
+not necessary anymore.
+
+* Dumped buffering code. The performance loss is 10%, but it caused
+bugs in systems with CRLF termination. The current solution is
+not definitive, though.
+
+* Bug fix: Made the behavior of s/A*/x/g (i.e. `s' command with a
+possibly empty LHS) more consistent:
+
+ pattern GNU sed 3.x GNU sed 4.x
+ B xBx xBx
+ BC xBxCx xBxCx
+ BAC xBxxCx xBxCx
+ BAAC xBxxCx xBxCx
+
+* Bug fix: the // empty regular expressions now refers to the last
+regular expression that was matched, rather than to the last
+regular expression that was compiled. This richer behavior seems
+to be the correct one (albeit neither one is POSIXLY_CORRECT).
+
+* Check for invalid backreferences in the RHS of the `s' command
+(e.g. s/1234/\1/)
+
+* Support for \[lLuUE] in the RHS of the `s' command like in Perl.
+
+* New regular expression matcher
+
+* Bug fix: if a file was redirected to be stdin, sed did not consume
+it. So
+ (sed d; sed G) < TESTFILE
+
+double-spaced TESTFILE, while the equivalent `useless use of cat'
+ cat TESTFILE | (sed d; sed G)
+
+printed nothing (which is the correct behavior). A test for this
+bug was added to the test suite.
+
+* The documentation is now much better, with a few examples provided,
+and a thorough description of regular expressions. The manual often
+refers to "GNU extensions", but if they are described here they are
+specific to this version.
+
+* Documented command-line option:
+ -r, --regexp-extended
+ Use extended regexps -- e.g. (abc+) instead of \(abc\+\)
+
+* Added feature to the `w' command and to the `w' option of the `s'
+command: if the file name is /dev/stderr, it means the standard
+error (inspired by awk); and similarly for /dev/stdout. This is
+disabled if POSIXLY_CORRECT is set.
+
+* Added `m' and `M' modifiers to `s' command for multi-line
+matching (Perl-style); in addresses, only `M' works.
+
+* Added `Q' command for `silent quit'; added ability to pass
+an exit code from a sed script to the caller.
+
+* Added `T' command for `branch if failed'.
+
+* Added `v' command, which is a do-nothing intended to fail on
+seds that do not support GNU sed 4.0's extensions.
+
+----------------------------------------------------------------------------
+Sed 3.02.80
+
+* Started new version nomenclature for pre-3.03 releases. (I'm being
+pessimistic in assuming that .90 won't give me enough breathing room.)
+
+* Bug fixes: the regncomp()/regnexec() interfaces proved to be inadequate to
+properly handle expressions such as "s/\</#/g". Re-abstracted the regex
+code in the sed/ tree, and now use the re_search_2() interface to the GNU
+regex routines. This change also fixed a bug where /./ did not match the
+NUL character. Had the glibc folk fix a bug in lib/regex.c where
+'s/0*\([0-9][0-9]\)/X\1X/' failed to match on input "002".
+
+* Added new command-line options:
+ -u, --unbuffered
+ Do not attempt to read-ahead more than required; do not buffer stdout.
+ -l N, --line-length=N
+ Specify the desired line-wrap length for the `l' command.
+ A length of "0" means "never wrap".
+
+* New internationalization translations added: fr ru de it el sk pt_BR sv
+(plus nl from 3.02a).
+
+* The s/// command now understands the following escapes
+(in both halves):
+ \a an "alert" (BEL)
+ \f a form-feed
+ \n a newline
+ \r a carriage-return
+ \t a horizontal tab
+ \v a vertical tab
+ \oNNN a character with the octal value NNN
+ \dNNN a character with the decimal value NNN
+ \xNN a character with the hexadecimal value NN
+This behavior is disabled if POSIXLY_CORRECT is set, at least for the
+time being (until I can be convinced that this behavior does not violate
+the POSIX standard). (Incidentally, \b (backspace) was omitted because
+of the conflict with the existing "word boundary" meaning. \ooo octal
+format was omitted because of the conflict with backreference syntax.)
+
+* If POSIXLY_CORRECT is set, the empty RE // now is the null match
+instead of "repeat the last REmatch". As far as I can tell
+this behavior is mandated by POSIX, but it would break too many
+legacy sed scripts to blithely change GNU sed's default behavior.
+
+----------------------------------------------------------------------------
+Sed 3.02a
+
+* Added internationalization support, and an initial (already out of date)
+set of Dutch message translations (both provided by Erick Branderhorst).
+
+* Added support for scripts like:
+ sed -e 1ifoo -e '$abar'
+(note no need for \ <newline> after a, i, and c commands).
+Also, conditionally (on NO_INPUT_INDENT) added
+experimental support for skipping leading whitespace on
+each {a,i,c} input line.
+
+* Added addressing of the form:
+ /foo/,+5 p (print from foo to 5th line following)
+ /foo/,~5 p (print from foo to next line whose line number is a multiple of 5)
+The first address of these can be any of the previously existing
+addressing types; the +N and ~N forms are only allowed as the
+second address of a range.
+
+* Added support for pseudo-address "0" as the first address in an
+address-range, simplifying scripts which happen to match the end
+address on the first line of input. For example, a script
+which deletes all lines from the beginning of the file to the
+first line which contains "foo" is now simply "sed 0,/foo/d",
+whereas before one had to go through contortions to deal with
+the possibility that "foo" might appear on the first line of
+the input.
+
+* Made NUL characters in regexps work "correctly" --- i.e., a NUL
+in a RE matches a NUL; it does not prematurely terminate the RE.
+(This only works in -f scripts, as the POSIX.1 exec*() interface
+only passes NUL-terminated strings, and so sed will only be able
+to see up to the first NUL in any -e scriptlet.)
+
+* Wherever a `;' is accepted as a command terminator, also allow a `}'
+or a `#' to appear. (This allows for less cluttered-looking scripts.)
+
+* Lots of internal changes that are only relevant to source junkies
+and development testing. Some of which might cause imperceptible
+performance improvements.
+
+----------------------------------------------------------------------------
+Sed 3.02
+
+* Fixed a bug in the parsing of character classes (e.g., /[[:space:]]/).
+Corrected an omission in djgpp/Makefile.am and an improper dependency
+in testsuite/Makefile.am.
+
+----------------------------------------------------------------------------
+Sed 3.01
+
+* This version of sed mainly contains bug fixes and portability
+enhancements, plus performance enhancements related to sed's handling
+of input files. Due to excess performance penalties, I have reverted
+(relative to 3.00) to using regex.c instead of the rx package for
+regular expression handling, at the expense of losing true POSIX.2
+BRE compatibility. However, performance related to regular expression
+handling *still* needs a fair bit of work.
+
+* One new feature has been added: regular expressions may be followed
+with an "I" directive ("i" was taken [the "i"nsert command]) to
+indicate that the regexp should be matched in a case-insensitive
+manner. Also of note are a new organization to the source code,
+new documentation, and a new maintainer.
+
+----------------------------------------------------------------------------
+Sed 3.0
+
+* This version of sed passes the new test-suite donated by
+Jason Molenda.
+
+* Overall performance has been improved in the following sense: Sed 3.0
+is often slightly slower than sed 2.05. On a few scripts, though, sed
+2.05 was so slow as to be nearly useless or to use up unreasonable
+amounts of memory. These problems have been fixed and in such cases,
+sed 3.0 should have acceptable performance.

+Because a working sed is a prerequisite for running the ``configure''
+script, I have provided the script ``bootstrap.sh'' which will attempt
+to build a version of sed adequate for running ``configure''. If it
+fails, edit the ``config.h'' file that was created according to the
+comments found therein, and then try running ``bootstrap.sh'' again.
+
+The bootstrap build is quite likely to babble on and on with
+various compiler warnings. You may want to tell bootstrap.sh
+how to invoke your compiler with warnings disabled. For example,
+with a Bourne-like shell and gcc one could use:
+ $ CC='gcc -w' sh bootstrap.sh
+or with a csh-like shell, one could try:
+ % env CC='gcc -w' sh bootstrap.sh
+
+Once you get a working version of sed, temporarily install sed/sed
+somewhere in your $PATH, and then really re-build the normal way
+(starting with ``sh configure''); the bootstrap version is almost
+certainly more crippled than it needs to be on your machine.
+
+I don't much care to hear about any bugs in ``bootstrap'' versions
+of sed beyond those which actually keep the ``bootstrap'' version from
+building, or sed's configure script from running properly. I am
+especially uninterested in compiler warnings from the bootstrap build.

+1 Introduction
+**************
+
+`sed' is a stream editor. A stream editor is used to perform basic text
+transformations on an input stream (a file or input from a pipeline).
+While in some ways similar to an editor which permits scripted edits
+(such as `ed'), `sed' works by making only one pass over the input(s),
+and is consequently more efficient. But it is `sed''s ability to
+filter text in a pipeline which particularly distinguishes it from
+other types of editors.
+
+

+
+2 Invocation
+************
+
+Normally `sed' is invoked like this:
+
+ sed SCRIPT INPUTFILE...
+
+ The full format for invoking `sed' is:
+
+ sed OPTIONS... [SCRIPT] [INPUTFILE...]
+
+ If you do not specify INPUTFILE, or if INPUTFILE is `-', `sed'
+filters the contents of the standard input. The SCRIPT is actually the
+first non-option parameter, which `sed' specially considers a script
+and not an input file if (and only if) none of the other OPTIONS
+specifies a script to be executed, that is if neither of the `-e' and
+`-f' options is specified.
+
+ `sed' may be invoked with the following command-line options:
+
+`--version'
+ Print out the version of `sed' that is being run and a copyright
+ notice, then exit.
+
+`--help'
+ Print a usage message briefly summarizing these command-line
+ options and the bug-reporting address, then exit.
+
+`-n'
+`--quiet'
+`--silent'
+ By default, `sed' prints out the pattern space at the end of each
+ cycle through the script (*note How `sed' works: Execution Cycle.).
+ These options disable this automatic printing, and `sed' only
+ produces output when explicitly told to via the `p' command.
+
+`-e SCRIPT'
+`--expression=SCRIPT'
+ Add the commands in SCRIPT to the set of commands to be run while
+ processing the input.
+
+`-f SCRIPT-FILE'
+`--file=SCRIPT-FILE'
+ Add the commands contained in the file SCRIPT-FILE to the set of
+ commands to be run while processing the input.
+
+`-i[SUFFIX]'
+`--in-place[=SUFFIX]'
+ This option specifies that files are to be edited in-place. GNU
+ `sed' does this by creating a temporary file and sending output to
+ this file rather than to the standard output.(1).
+
+ This option implies `-s'.
+
+ When the end of the file is reached, the temporary file is renamed
+ to the output file's original name. The extension, if supplied,
+ is used to modify the name of the old file before renaming the
+ temporary file, thereby making a backup copy(2)).
+
+ This rule is followed: if the extension doesn't contain a `*',
+ then it is appended to the end of the current filename as a
+ suffix; if the extension does contain one or more `*' characters,
+ then _each_ asterisk is replaced with the current filename. This
+ allows you to add a prefix to the backup file, instead of (or in
+ addition to) a suffix, or even to place backup copies of the
+ original files into another directory (provided the directory
+ already exists).
+
+ If no extension is supplied, the original file is overwritten
+ without making a backup.
+
+`-l N'
+`--line-length=N'
+ Specify the default line-wrap length for the `l' command. A
+ length of 0 (zero) means to never wrap long lines. If not
+ specified, it is taken to be 70.
+
+`--posix'
+ GNU `sed' includes several extensions to POSIX sed. In order to
+ simplify writing portable scripts, this option disables all the
+ extensions that this manual documents, including additional
+ commands. Most of the extensions accept `sed' programs that are
+ outside the syntax mandated by POSIX, but some of them (such as
+ the behavior of the `N' command described in *note Reporting
+ Bugs::) actually violate the standard. If you want to disable
+ only the latter kind of extension, you can set the
+ `POSIXLY_CORRECT' variable to a non-empty value.
+
+`-b'
+`--binary'
+ This option is available on every platform, but is only effective
+ where the operating system makes a distinction between text files
+ and binary files. When such a distinction is made--as is the case
+ for MS-DOS, Windows, Cygwin--text files are composed of lines
+ separated by a carriage return _and_ a line feed character, and
+ `sed' does not see the ending CR. When this option is specified,
+ `sed' will open input files in binary mode, thus not requesting
+ this special processing and considering lines to end at a line
+ feed.
+
+`--follow-symlinks'
+ This option is available only on platforms that support symbolic
+ links and has an effect only if option `-i' is specified. In this
+ case, if the file that is specified on the command line is a
+ symbolic link, `sed' will follow the link and edit the ultimate
+ destination of the link. The default behavior is to break the
+ symbolic link, so that the link destination will not be modified.
+
+`-r'
+`--regexp-extended'
+ Use extended regular expressions rather than basic regular
+ expressions. Extended regexps are those that `egrep' accepts;
+ they can be clearer because they usually have less backslashes,
+ but are a GNU extension and hence scripts that use them are not
+ portable. *Note Extended regular expressions: Extended regexps.
+
+`-s'
+`--separate'
+ By default, `sed' will consider the files specified on the command
+ line as a single continuous long stream. This GNU `sed' extension
+ allows the user to consider them as separate files: range
+ addresses (such as `/abc/,/def/') are not allowed to span several
+ files, line numbers are relative to the start of each file, `$'
+ refers to the last line of each file, and files invoked from the
+ `R' commands are rewound at the start of each file.
+
+`-u'
+`--unbuffered'
+ Buffer both input and output as minimally as practical. (This is
+ particularly useful if the input is coming from the likes of `tail
+ -f', and you wish to see the transformed output as soon as
+ possible.)
+
+
+ If no `-e', `-f', `--expression', or `--file' options are given on
+the command-line, then the first non-option argument on the command
+line is taken to be the SCRIPT to be executed.
+
+ If any command-line parameters remain after processing the above,
+these parameters are interpreted as the names of input files to be
+processed. A file name of `-' refers to the standard input stream.
+The standard input will be processed if no file names are specified.
+
+ ---------- Footnotes ----------
+
+ (1) This applies to commands such as `=', `a', `c', `i', `l', `p'.
+You can still write to the standard output by using the `w' or `W'
+commands together with the `/dev/stdout' special file
+
+ (2) Note that GNU `sed' creates the backup file whether or not any
+output is actually changed.

+3 `sed' Programs
+****************
+
+A `sed' program consists of one or more `sed' commands, passed in by
+one or more of the `-e', `-f', `--expression', and `--file' options, or
+the first non-option argument if zero of these options are used. This
+document will refer to "the" `sed' script; this is understood to mean
+the in-order catenation of all of the SCRIPTs and SCRIPT-FILEs passed
+in.
+
+ Each `sed' command consists of an optional address or address range,
+followed by a one-character command name and any additional
+command-specific code.

+
+3.1 How `sed' Works
+===================
+
+`sed' maintains two data buffers: the active _pattern_ space, and the
+auxiliary _hold_ space. Both are initially empty.
+
+ `sed' operates by performing the following cycle on each lines of
+input: first, `sed' reads one line from the input stream, removes any
+trailing newline, and places it in the pattern space. Then commands
+are executed; each command can have an address associated to it:
+addresses are a kind of condition code, and a command is only executed
+if the condition is verified before the command is to be executed.
+
+ When the end of the script is reached, unless the `-n' option is in
+use, the contents of pattern space are printed out to the output
+stream, adding back the trailing newline if it was removed.(1) Then the
+next cycle starts for the next input line.
+
+ Unless special commands (like `D') are used, the pattern space is
+deleted between two cycles. The hold space, on the other hand, keeps
+its data between cycles (see commands `h', `H', `x', `g', `G' to move
+data between both buffers).
+
+ ---------- Footnotes ----------
+
+ (1) Actually, if `sed' prints a line without the terminating
+newline, it will nevertheless print the missing newline as soon as more
+text is sent to the same output stream, which gives the "least expected
+surprise" even though it does not make commands like `sed -n p' exactly
+identical to `cat'.
+
+
+File: sed.info, Node: Addresses, Next: Regular Expressions, Prev: Execution Cycle, Up: sed Programs
+
+3.2 Selecting lines with `sed'
+==============================
+
+Addresses in a `sed' script can be in any of the following forms:
+`NUMBER'
+ Specifying a line number will match only that line in the input.
+ (Note that `sed' counts lines continuously across all input files
+ unless `-i' or `-s' options are specified.)
+
+`FIRST~STEP'
+ This GNU extension matches every STEPth line starting with line
+ FIRST. In particular, lines will be selected when there exists a
+ non-negative N such that the current line-number equals FIRST + (N
+ * STEP). Thus, to select the odd-numbered lines, one would use
+ `1~2'; to pick every third line starting with the second, `2~3'
+ would be used; to pick every fifth line starting with the tenth,
+ use `10~5'; and `50~0' is just an obscure way of saying `50'.
+
+`$'
+ This address matches the last line of the last file of input, or
+ the last line of each file when the `-i' or `-s' options are
+ specified.
+
+`/REGEXP/'
+ This will select any line which matches the regular expression
+ REGEXP. If REGEXP itself includes any `/' characters, each must
+ be escaped by a backslash (`\').
+
+ The empty regular expression `//' repeats the last regular
+ expression match (the same holds if the empty regular expression is
+ passed to the `s' command). Note that modifiers to regular
+ expressions are evaluated when the regular expression is compiled,
+ thus it is invalid to specify them together with the empty regular
+ expression.
+
+`\%REGEXP%'
+ (The `%' may be replaced by any other single character.)
+
+ This also matches the regular expression REGEXP, but allows one to
+ use a different delimiter than `/'. This is particularly useful
+ if the REGEXP itself contains a lot of slashes, since it avoids
+ the tedious escaping of every `/'. If REGEXP itself includes any
+ delimiter characters, each must be escaped by a backslash (`\').
+
+`/REGEXP/I'
+`\%REGEXP%I'
+ The `I' modifier to regular-expression matching is a GNU extension
+ which causes the REGEXP to be matched in a case-insensitive manner.
+
+`/REGEXP/M'
+`\%REGEXP%M'
+ The `M' modifier to regular-expression matching is a GNU `sed'
+ extension which causes `^' and `$' to match respectively (in
+ addition to the normal behavior) the empty string after a newline,
+ and the empty string before a newline. There are special character
+ sequences (`\`' and `\'') which always match the beginning or the
+ end of the buffer. `M' stands for `multi-line'.
+
+
+ If no addresses are given, then all lines are matched; if one
+address is given, then only lines matching that address are matched.
+
+ An address range can be specified by specifying two addresses
+separated by a comma (`,'). An address range matches lines starting
+from where the first address matches, and continues until the second
+address matches (inclusively).
+
+ If the second address is a REGEXP, then checking for the ending
+match will start with the line _following_ the line which matched the
+first address: a range will always span at least two lines (except of
+course if the input stream ends).
+
+ If the second address is a NUMBER less than (or equal to) the line
+matching the first address, then only the one line is matched.
+
+ GNU `sed' also supports some special two-address forms; all these
+are GNU extensions:
+`0,/REGEXP/'
+ A line number of `0' can be used in an address specification like
+ `0,/REGEXP/' so that `sed' will try to match REGEXP in the first
+ input line too. In other words, `0,/REGEXP/' is similar to
+ `1,/REGEXP/', except that if ADDR2 matches the very first line of
+ input the `0,/REGEXP/' form will consider it to end the range,
+ whereas the `1,/REGEXP/' form will match the beginning of its
+ range and hence make the range span up to the _second_ occurrence
+ of the regular expression.
+
+ Note that this is the only place where the `0' address makes
+ sense; there is no 0-th line and commands which are given the `0'
+ address in any other way will give an error.
+
+`ADDR1,+N'
+ Matches ADDR1 and the N lines following ADDR1.
+
+`ADDR1,~N'
+ Matches ADDR1 and the lines following ADDR1 until the next line
+ whose input line number is a multiple of N.
+
+ Appending the `!' character to the end of an address specification
+negates the sense of the match. That is, if the `!' character follows
+an address range, then only lines which do _not_ match the address range
+will be selected. This also works for singleton addresses, and,
+perhaps perversely, for the null address.
+
+

+
+3.3 Overview of Regular Expression Syntax
+=========================================
+
+To know how to use `sed', people should understand regular expressions
+("regexp" for short). A regular expression is a pattern that is
+matched against a subject string from left to right. Most characters
+are "ordinary": they stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the
+pattern
+
+ The quick brown fox
+
+matches a portion of a subject string that is identical to itself. The
+power of regular expressions comes from the ability to include
+alternatives and repetitions in the pattern. These are encoded in the
+pattern by the use of "special characters", which do not stand for
+themselves but instead are interpreted in some special way. Here is a
+brief description of regular expression syntax as used in `sed'.
+
+`CHAR'
+ A single ordinary character matches itself.
+
+`*'
+ Matches a sequence of zero or more instances of matches for the
+ preceding regular expression, which must be an ordinary character,
+ a special character preceded by `\', a `.', a grouped regexp (see
+ below), or a bracket expression. As a GNU extension, a postfixed
+ regular expression can also be followed by `*'; for example, `a**'
+ is equivalent to `a*'. POSIX 1003.1-2001 says that `*' stands for
+ itself when it appears at the start of a regular expression or
+ subexpression, but many nonGNU implementations do not support this
+ and portable scripts should instead use `\*' in these contexts.
+
+`\+'
+ As `*', but matches one or more. It is a GNU extension.
+
+`\?'
+ As `*', but only matches zero or one. It is a GNU extension.
+
+`\{I\}'
+ As `*', but matches exactly I sequences (I is a decimal integer;
+ for portability, keep it between 0 and 255 inclusive).
+
+`\{I,J\}'
+ Matches between I and J, inclusive, sequences.
+
+`\{I,\}'
+ Matches more than or equal to I sequences.
+
+`\(REGEXP\)'
+ Groups the inner REGEXP as a whole, this is used to:
+
+ * Apply postfix operators, like `\(abcd\)*': this will search
+ for zero or more whole sequences of `abcd', while `abcd*'
+ would search for `abc' followed by zero or more occurrences
+ of `d'. Note that support for `\(abcd\)*' is required by
+ POSIX 1003.1-2001, but many non-GNU implementations do not
+ support it and hence it is not universally portable.
+
+ * Use back references (see below).
+
+`.'
+ Matches any character, including newline.
+
+`^'
+ Matches the null string at beginning of the pattern space, i.e.
+ what appears after the circumflex must appear at the beginning of
+ the pattern space.
+
+ In most scripts, pattern space is initialized to the content of
+ each line (*note How `sed' works: Execution Cycle.). So, it is a
+ useful simplification to think of `^#include' as matching only
+ lines where `#include' is the first thing on line--if there are
+ spaces before, for example, the match fails. This simplification
+ is valid as long as the original content of pattern space is not
+ modified, for example with an `s' command.
+
+ `^' acts as a special character only at the beginning of the
+ regular expression or subexpression (that is, after `\(' or `\|').
+ Portable scripts should avoid `^' at the beginning of a
+ subexpression, though, as POSIX allows implementations that treat
+ `^' as an ordinary character in that context.
+
+`$'
+ It is the same as `^', but refers to end of pattern space. `$'
+ also acts as a special character only at the end of the regular
+ expression or subexpression (that is, before `\)' or `\|'), and
+ its use at the end of a subexpression is not portable.
+
+`[LIST]'
+`[^LIST]'
+ Matches any single character in LIST: for example, `[aeiou]'
+ matches all vowels. A list may include sequences like
+ `CHAR1-CHAR2', which matches any character between (inclusive)
+ CHAR1 and CHAR2.
+
+ A leading `^' reverses the meaning of LIST, so that it matches any
+ single character _not_ in LIST. To include `]' in the list, make
+ it the first character (after the `^' if needed), to include `-'
+ in the list, make it the first or last; to include `^' put it
+ after the first character.
+
+ The characters `$', `*', `.', `[', and `\' are normally not
+ special within LIST. For example, `[\*]' matches either `\' or
+ `*', because the `\' is not special here. However, strings like
+ `[.ch.]', `[=a=]', and `[:space:]' are special within LIST and
+ represent collating symbols, equivalence classes, and character
+ classes, respectively, and `[' is therefore special within LIST
+ when it is followed by `.', `=', or `:'. Also, when not in
+ `POSIXLY_CORRECT' mode, special escapes like `\n' and `\t' are
+ recognized within LIST. *Note Escapes::.
+
+`REGEXP1\|REGEXP2'
+ Matches either REGEXP1 or REGEXP2. Use parentheses to use complex
+ alternative regular expressions. The matching process tries each
+ alternative in turn, from left to right, and the first one that
+ succeeds is used. It is a GNU extension.
+
+`REGEXP1REGEXP2'
+ Matches the concatenation of REGEXP1 and REGEXP2. Concatenation
+ binds more tightly than `\|', `^', and `$', but less tightly than
+ the other regular expression operators.
+
+`\DIGIT'
+ Matches the DIGIT-th `\(...\)' parenthesized subexpression in the
+ regular expression. This is called a "back reference".
+ Subexpressions are implicity numbered by counting occurrences of
+ `\(' left-to-right.
+
+`\n'
+ Matches the newline character.
+
+`\CHAR'
+ Matches CHAR, where CHAR is one of `$', `*', `.', `[', `\', or `^'.
+ Note that the only C-like backslash sequences that you can
+ portably assume to be interpreted are `\n' and `\\'; in particular
+ `\t' is not portable, and matches a `t' under most implementations
+ of `sed', rather than a tab character.
+
+
+ Note that the regular expression matcher is greedy, i.e., matches
+are attempted from left to right and, if two or more matches are
+possible starting at the same character, it selects the longest.
+
+Examples:
+`abcdef'
+ Matches `abcdef'.
+
+`a*b'
+ Matches zero or more `a's followed by a single `b'. For example,
+ `b' or `aaaaab'.
+
+`a\?b'
+ Matches `b' or `ab'.
+
+`a\+b\+'
+ Matches one or more `a's followed by one or more `b's: `ab' is the
+ shortest possible match, but other examples are `aaaab' or
+ `abbbbb' or `aaaaaabbbbbbb'.
+
+`.*'
+`.\+'
+ These two both match all the characters in a string; however, the
+ first matches every string (including the empty string), while the
+ second matches only strings containing at least one character.
+
+`^main.*(.*)'
+ his matches a string starting with `main', followed by an opening
+ and closing parenthesis. The `n', `(' and `)' need not be
+ adjacent.
+
+`^#'
+ This matches a string beginning with `#'.
+
+`\\$'
+ This matches a string ending with a single backslash. The regexp
+ contains two backslashes for escaping.
+
+`\$'
+ Instead, this matches a string consisting of a single dollar sign,
+ because it is escaped.
+
+`[a-zA-Z0-9]'
+ In the C locale, this matches any ASCII letters or digits.
+
+`[^ tab]\+'
+ (Here `tab' stands for a single tab character.) This matches a
+ string of one or more characters, none of which is a space or a
+ tab. Usually this means a word.
+
+`^\(.*\)\n\1$'
+ This matches a string consisting of two equal substrings separated
+ by a newline.
+
+`.\{9\}A$'
+ This matches nine characters followed by an `A'.
+
+`^.\{15\}A'
+ This matches the start of a string that contains 16 characters,
+ the last of which is an `A'.

+
+3.4 Often-Used Commands
+=======================
+
+If you use `sed' at all, you will quite likely want to know these
+commands.
+
+`#'
+ [No addresses allowed.]
+
+ The `#' character begins a comment; the comment continues until
+ the next newline.
+
+ If you are concerned about portability, be aware that some
+ implementations of `sed' (which are not POSIX conformant) may only
+ support a single one-line comment, and then only when the very
+ first character of the script is a `#'.
+
+ Warning: if the first two characters of the `sed' script are `#n',
+ then the `-n' (no-autoprint) option is forced. If you want to put
+ a comment in the first line of your script and that comment begins
+ with the letter `n' and you do not want this behavior, then be
+ sure to either use a capital `N', or place at least one space
+ before the `n'.
+
+`q [EXIT-CODE]'
+ This command only accepts a single address.
+
+ Exit `sed' without processing any more commands or input. Note
+ that the current pattern space is printed if auto-print is not
+ disabled with the `-n' options. The ability to return an exit
+ code from the `sed' script is a GNU `sed' extension.
+
+`d'
+ Delete the pattern space; immediately start next cycle.
+
+`p'
+ Print out the pattern space (to the standard output). This
+ command is usually only used in conjunction with the `-n'
+ command-line option.
+
+`n'
+ If auto-print is not disabled, print the pattern space, then,
+ regardless, replace the pattern space with the next line of input.
+ If there is no more input then `sed' exits without processing any
+ more commands.
+
+`{ COMMANDS }'
+ A group of commands may be enclosed between `{' and `}' characters.
+ This is particularly useful when you want a group of commands to
+ be triggered by a single address (or address-range) match.
+
+
+
+File: sed.info, Node: The "s" Command, Next: Other Commands, Prev: Common Commands, Up: sed Programs
+
+3.5 The `s' Command
+===================
+
+The syntax of the `s' (as in substitute) command is
+`s/REGEXP/REPLACEMENT/FLAGS'. The `/' characters may be uniformly
+replaced by any other single character within any given `s' command.
+The `/' character (or whatever other character is used in its stead)
+can appear in the REGEXP or REPLACEMENT only if it is preceded by a `\'
+character.
+
+ The `s' command is probably the most important in `sed' and has a
+lot of different options. Its basic concept is simple: the `s' command
+attempts to match the pattern space against the supplied REGEXP; if the
+match is successful, then that portion of the pattern space which was
+matched is replaced with REPLACEMENT.
+
+ The REPLACEMENT can contain `\N' (N being a number from 1 to 9,
+inclusive) references, which refer to the portion of the match which is
+contained between the Nth `\(' and its matching `\)'. Also, the
+REPLACEMENT can contain unescaped `&' characters which reference the
+whole matched portion of the pattern space. Finally, as a GNU `sed'
+extension, you can include a special sequence made of a backslash and
+one of the letters `L', `l', `U', `u', or `E'. The meaning is as
+follows:
+
+`\L'
+ Turn the replacement to lowercase until a `\U' or `\E' is found,
+
+`\l'
+ Turn the next character to lowercase,
+
+`\U'
+ Turn the replacement to uppercase until a `\L' or `\E' is found,
+
+`\u'
+ Turn the next character to uppercase,
+
+`\E'
+ Stop case conversion started by `\L' or `\U'.
+
+ To include a literal `\', `&', or newline in the final replacement,
+be sure to precede the desired `\', `&', or newline in the REPLACEMENT
+with a `\'.
+
+ The `s' command can be followed by zero or more of the following
+FLAGS:
+
+`g'
+ Apply the replacement to _all_ matches to the REGEXP, not just the
+ first.
+
+`NUMBER'
+ Only replace the NUMBERth match of the REGEXP.
+
+ Note: the POSIX standard does not specify what should happen when
+ you mix the `g' and NUMBER modifiers, and currently there is no
+ widely agreed upon meaning across `sed' implementations. For GNU
+ `sed', the interaction is defined to be: ignore matches before the
+ NUMBERth, and then match and replace all matches from the NUMBERth
+ on.
+
+`p'
+ If the substitution was made, then print the new pattern space.
+
+ Note: when both the `p' and `e' options are specified, the
+ relative ordering of the two produces very different results. In
+ general, `ep' (evaluate then print) is what you want, but
+ operating the other way round can be useful for debugging. For
+ this reason, the current version of GNU `sed' interprets specially
+ the presence of `p' options both before and after `e', printing
+ the pattern space before and after evaluation, while in general
+ flags for the `s' command show their effect just once. This
+ behavior, although documented, might change in future versions.
+
+`w FILE-NAME'
+ If the substitution was made, then write out the result to the
+ named file. As a GNU `sed' extension, two special values of
+ FILE-NAME are supported: `/dev/stderr', which writes the result to
+ the standard error, and `/dev/stdout', which writes to the standard
+ output.(1)
+
+`e'
+ This command allows one to pipe input from a shell command into
+ pattern space. If a substitution was made, the command that is
+ found in pattern space is executed and pattern space is replaced
+ with its output. A trailing newline is suppressed; results are
+ undefined if the command to be executed contains a NUL character.
+ This is a GNU `sed' extension.
+
+`I'
+`i'
+ The `I' modifier to regular-expression matching is a GNU extension
+ which makes `sed' match REGEXP in a case-insensitive manner.
+
+`M'
+`m'
+ The `M' modifier to regular-expression matching is a GNU `sed'
+ extension which causes `^' and `$' to match respectively (in
+ addition to the normal behavior) the empty string after a newline,
+ and the empty string before a newline. There are special character
+ sequences (`\`' and `\'') which always match the beginning or the
+ end of the buffer. `M' stands for `multi-line'.
+
+
+ ---------- Footnotes ----------
+
+ (1) This is equivalent to `p' unless the `-i' option is being used.

+
+3.6 Less Frequently-Used Commands
+=================================
+
+Though perhaps less frequently used than those in the previous section,
+some very small yet useful `sed' scripts can be built with these
+commands.
+
+`y/SOURCE-CHARS/DEST-CHARS/'
+ (The `/' characters may be uniformly replaced by any other single
+ character within any given `y' command.)
+
+ Transliterate any characters in the pattern space which match any
+ of the SOURCE-CHARS with the corresponding character in DEST-CHARS.
+
+ Instances of the `/' (or whatever other character is used in its
+ stead), `\', or newlines can appear in the SOURCE-CHARS or
+ DEST-CHARS lists, provide that each instance is escaped by a `\'.
+ The SOURCE-CHARS and DEST-CHARS lists _must_ contain the same
+ number of characters (after de-escaping).
+
+`a\'
+`TEXT'
+ As a GNU extension, this command accepts two addresses.
+
+ Queue the lines of text which follow this command (each but the
+ last ending with a `\', which are removed from the output) to be
+ output at the end of the current cycle, or when the next input
+ line is read.
+
+ Escape sequences in TEXT are processed, so you should use `\\' in
+ TEXT to print a single backslash.
+
+ As a GNU extension, if between the `a' and the newline there is
+ other than a whitespace-`\' sequence, then the text of this line,
+ starting at the first non-whitespace character after the `a', is
+ taken as the first line of the TEXT block. (This enables a
+ simplification in scripting a one-line add.) This extension also
+ works with the `i' and `c' commands.
+
+`i\'
+`TEXT'
+ As a GNU extension, this command accepts two addresses.
+
+ Immediately output the lines of text which follow this command
+ (each but the last ending with a `\', which are removed from the
+ output).
+
+`c\'
+`TEXT'
+ Delete the lines matching the address or address-range, and output
+ the lines of text which follow this command (each but the last
+ ending with a `\', which are removed from the output) in place of
+ the last line (or in place of each line, if no addresses were
+ specified). A new cycle is started after this command is done,
+ since the pattern space will have been deleted.
+
+`='
+ As a GNU extension, this command accepts two addresses.
+
+ Print out the current input line number (with a trailing newline).
+
+`l N'
+ Print the pattern space in an unambiguous form: non-printable
+ characters (and the `\' character) are printed in C-style escaped
+ form; long lines are split, with a trailing `\' character to
+ indicate the split; the end of each line is marked with a `$'.
+
+ N specifies the desired line-wrap length; a length of 0 (zero)
+ means to never wrap long lines. If omitted, the default as
+ specified on the command line is used. The N parameter is a GNU
+ `sed' extension.
+
+`r FILENAME'
+ As a GNU extension, this command accepts two addresses.
+
+ Queue the contents of FILENAME to be read and inserted into the
+ output stream at the end of the current cycle, or when the next
+ input line is read. Note that if FILENAME cannot be read, it is
+ treated as if it were an empty file, without any error indication.
+
+ As a GNU `sed' extension, the special value `/dev/stdin' is
+ supported for the file name, which reads the contents of the
+ standard input.
+
+`w FILENAME'
+ Write the pattern space to FILENAME. As a GNU `sed' extension,
+ two special values of FILE-NAME are supported: `/dev/stderr',
+ which writes the result to the standard error, and `/dev/stdout',
+ which writes to the standard output.(1)
+
+ The file will be created (or truncated) before the first input
+ line is read; all `w' commands (including instances of `w' flag on
+ successful `s' commands) which refer to the same FILENAME are
+ output without closing and reopening the file.
+
+`D'
+ Delete text in the pattern space up to the first newline. If any
+ text is left, restart cycle with the resultant pattern space
+ (without reading a new line of input), otherwise start a normal
+ new cycle.
+
+`N'
+ Add a newline to the pattern space, then append the next line of
+ input to the pattern space. If there is no more input then `sed'
+ exits without processing any more commands.
+
+`P'
+ Print out the portion of the pattern space up to the first newline.
+
+`h'
+ Replace the contents of the hold space with the contents of the
+ pattern space.
+
+`H'
+ Append a newline to the contents of the hold space, and then
+ append the contents of the pattern space to that of the hold space.
+
+`g'
+ Replace the contents of the pattern space with the contents of the
+ hold space.
+
+`G'
+ Append a newline to the contents of the pattern space, and then
+ append the contents of the hold space to that of the pattern space.
+
+`x'
+ Exchange the contents of the hold and pattern spaces.
+
+
+ ---------- Footnotes ----------
+

+3.7 Commands for `sed' gurus
+============================
+
+In most cases, use of these commands indicates that you are probably
+better off programming in something like `awk' or Perl. But
+occasionally one is committed to sticking with `sed', and these
+commands can enable one to write quite convoluted scripts.
+
+`: LABEL'
+ [No addresses allowed.]
+
+ Specify the location of LABEL for branch commands. In all other
+ respects, a no-op.
+
+`b LABEL'
+ Unconditionally branch to LABEL. The LABEL may be omitted, in
+ which case the next cycle is started.
+
+`t LABEL'
+ Branch to LABEL only if there has been a successful `s'ubstitution
+ since the last input line was read or conditional branch was taken.
+ The LABEL may be omitted, in which case the next cycle is started.
+
+
+
+File: sed.info, Node: Extended Commands, Next: Escapes, Prev: Programming Commands, Up: sed Programs
+
+3.8 Commands Specific to GNU `sed'
+==================================
+
+These commands are specific to GNU `sed', so you must use them with
+care and only when you are sure that hindering portability is not evil.
+They allow you to check for GNU `sed' extensions or to do tasks that
+are required quite often, yet are unsupported by standard `sed's.
+
+`e [COMMAND]'
+ This command allows one to pipe input from a shell command into
+ pattern space. Without parameters, the `e' command executes the
+ command that is found in pattern space and replaces the pattern
+ space with the output; a trailing newline is suppressed.
+
+ If a parameter is specified, instead, the `e' command interprets
+ it as a command and sends its output to the output stream (like
+ `r' does). The command can run across multiple lines, all but the
+ last ending with a back-slash.
+
+ In both cases, the results are undefined if the command to be
+ executed contains a NUL character.
+
+`L N'
+ This GNU `sed' extension fills and joins lines in pattern space to
+ produce output lines of (at most) N characters, like `fmt' does;
+ if N is omitted, the default as specified on the command line is
+ used. This command is considered a failed experiment and unless
+ there is enough request (which seems unlikely) will be removed in
+ future versions.
+
+`Q [EXIT-CODE]'
+ This command only accepts a single address.
+
+ This command is the same as `q', but will not print the contents
+ of pattern space. Like `q', it provides the ability to return an
+ exit code to the caller.
+
+ This command can be useful because the only alternative ways to
+ accomplish this apparently trivial function are to use the `-n'
+ option (which can unnecessarily complicate your script) or
+ resorting to the following snippet, which wastes time by reading
+ the whole file without any visible effect:
+
+ :eat
+ $d Quit silently on the last line
+ N Read another line, silently
+ g Overwrite pattern space each time to save memory
+ b eat
+
+`R FILENAME'
+ Queue a line of FILENAME to be read and inserted into the output
+ stream at the end of the current cycle, or when the next input
+ line is read. Note that if FILENAME cannot be read, or if its end
+ is reached, no line is appended, without any error indication.
+
+ As with the `r' command, the special value `/dev/stdin' is
+ supported for the file name, which reads a line from the standard
+ input.
+
+`T LABEL'
+ Branch to LABEL only if there have been no successful
+ `s'ubstitutions since the last input line was read or conditional
+ branch was taken. The LABEL may be omitted, in which case the next
+ cycle is started.
+
+`v VERSION'
+ This command does nothing, but makes `sed' fail if GNU `sed'
+ extensions are not supported, simply because other versions of
+ `sed' do not implement it. In addition, you can specify the
+ version of `sed' that your script requires, such as `4.0.5'. The
+ default is `4.0' because that is the first version that
+ implemented this command.
+
+ This command enables all GNU extensions even if `POSIXLY_CORRECT'
+ is set in the environment.
+
+`W FILENAME'
+ Write to the given filename the portion of the pattern space up to
+ the first newline. Everything said under the `w' command about
+ file handling holds here too.
+
+`z'
+ This command empties the content of pattern space. It is usually
+ the same as `s/.*//', but is more efficient and works in the
+ presence of invalid multibyte sequences in the input stream.
+ POSIX mandates that such sequences are _not_ matched by `.', so
+ that there is no portable way to clear `sed''s buffers in the
+ middle of the script in most multibyte locales (including UTF-8
+ locales).

+
+3.9 GNU Extensions for Escapes in Regular Expressions
+=====================================================
+
+Until this chapter, we have only encountered escapes of the form `\^',
+which tell `sed' not to interpret the circumflex as a special
+character, but rather to take it literally. For example, `\*' matches
+a single asterisk rather than zero or more backslashes.
+
+ This chapter introduces another kind of escape(1)--that is, escapes
+that are applied to a character or sequence of characters that
+ordinarily are taken literally, and that `sed' replaces with a special
+character. This provides a way of encoding non-printable characters in
+patterns in a visible manner. There is no restriction on the
+appearance of non-printing characters in a `sed' script but when a
+script is being prepared in the shell or by text editing, it is usually
+easier to use one of the following escape sequences than the binary
+character it represents:
+
+ The list of these escapes is:
+
+`\a'
+ Produces or matches a BEL character, that is an "alert" (ASCII 7).
+
+`\f'
+ Produces or matches a form feed (ASCII 12).
+
+`\n'
+ Produces or matches a newline (ASCII 10).
+
+`\r'
+ Produces or matches a carriage return (ASCII 13).
+
+`\t'
+ Produces or matches a horizontal tab (ASCII 9).
+
+`\v'
+ Produces or matches a so called "vertical tab" (ASCII 11).
+
+`\cX'
+ Produces or matches `CONTROL-X', where X is any character. The
+ precise effect of `\cX' is as follows: if X is a lower case
+ letter, it is converted to upper case. Then bit 6 of the
+ character (hex 40) is inverted. Thus `\cz' becomes hex 1A, but
+ `\c{' becomes hex 3B, while `\c;' becomes hex 7B.
+
+`\dXXX'
+ Produces or matches a character whose decimal ASCII value is XXX.
+
+`\oXXX'
+ Produces or matches a character whose octal ASCII value is XXX.
+
+`\xXX'
+ Produces or matches a character whose hexadecimal ASCII value is
+ XX.
+
+ `\b' (backspace) was omitted because of the conflict with the
+existing "word boundary" meaning.
+
+ Other escapes match a particular character class and are valid only
+in regular expressions:
+
+`\w'
+ Matches any "word" character. A "word" character is any letter or
+ digit or the underscore character.
+
+`\W'
+ Matches any "non-word" character.
+
+`\b'
+ Matches a word boundary; that is it matches if the character to
+ the left is a "word" character and the character to the right is a
+ "non-word" character, or vice-versa.
+
+`\B'
+ Matches everywhere but on a word boundary; that is it matches if
+ the character to the left and the character to the right are
+ either both "word" characters or both "non-word" characters.
+
+`\`'
+ Matches only at the start of pattern space. This is different
+ from `^' in multi-line mode.
+
+`\''
+ Matches only at the end of pattern space. This is different from
+ `$' in multi-line mode.
+
+
+ ---------- Footnotes ----------
+
+ (1) All the escapes introduced here are GNU extensions, with the
+exception of `\n'. In basic regular expression mode, setting
+`POSIXLY_CORRECT' disables them inside bracket expressions.

+
+4.1 Centering Lines
+===================
+
+This script centers all lines of a file on a 80 columns width. To
+change that width, the number in `\{...\}' must be replaced, and the
+number of added spaces also must be changed.
+
+ Note how the buffer commands are used to separate parts in the
+regular expressions to be matched--this is a common technique.
+
+ #!/usr/bin/sed -f
+
+ # Put 80 spaces in the buffer
+ 1 {
+ x
+ s/^$/ /
+ s/^.*$/&&&&&&&&/
+ x
+ }
+
+ # del leading and trailing spaces
+ y/tab/ /
+ s/^ *//
+ s/ *$//
+
+ # add a newline and 80 spaces to end of line
+ G
+
+ # keep first 81 chars (80 + a newline)
+ s/^\(.\{81\}\).*$/\1/
+
+ # \2 matches half of the spaces, which are moved to the beginning
+ s/^\(.*\)\n\(.*\)\2/\2\1/
+
+
+File: sed.info, Node: Increment a number, Next: Rename files to lower case, Prev: Centering lines, Up: Examples
+
+4.2 Increment a Number
+======================
+
+This script is one of a few that demonstrate how to do arithmetic in
+`sed'. This is indeed possible,(1) but must be done manually.
+
+ To increment one number you just add 1 to last digit, replacing it
+by the following digit. There is one exception: when the digit is a
+nine the previous digits must be also incremented until you don't have
+a nine.
+
+ This solution by Bruno Haible is very clever and smart because it
+uses a single buffer; if you don't have this limitation, the algorithm
+used in *note Numbering lines: cat -n, is faster. It works by
+replacing trailing nines with an underscore, then using multiple `s'
+commands to increment the last digit, and then again substituting
+underscores with zeros.
+
+ #!/usr/bin/sed -f
+
+ /[^0-9]/ d
+
+ # replace all leading 9s by _ (any other character except digits, could
+ # be used)
+ :d
+ s/9\(_*\)$/_\1/
+ td
+
+ # incr last digit only. The first line adds a most-significant
+ # digit of 1 if we have to add a digit.
+ #
+ # The `tn' commands are not necessary, but make the thing
+ # faster
+
+ s/^\(_*\)$/1\1/; tn
+ s/8\(_*\)$/9\1/; tn
+ s/7\(_*\)$/8\1/; tn
+ s/6\(_*\)$/7\1/; tn
+ s/5\(_*\)$/6\1/; tn
+ s/4\(_*\)$/5\1/; tn
+ s/3\(_*\)$/4\1/; tn
+ s/2\(_*\)$/3\1/; tn
+ s/1\(_*\)$/2\1/; tn
+ s/0\(_*\)$/1\1/; tn

+File: sed.info, Node: Rename files to lower case, Next: Print bash environment, Prev: Increment a number, Up: Examples
+
+4.3 Rename Files to Lower Case
+==============================
+
+This is a pretty strange use of `sed'. We transform text, and
+transform it to be shell commands, then just feed them to shell. Don't
+worry, even worse hacks are done when using `sed'; I have seen a script
+converting the output of `date' into a `bc' program!
+
+ The main body of this is the `sed' script, which remaps the name
+from lower to upper (or vice-versa) and even checks out if the remapped
+name is the same as the original name. Note how the script is
+parameterized using shell variables and proper quoting.
+
+ #! /bin/sh
+ # rename files to lower/upper case...
+ #
+ # usage:
+ # move-to-lower *

+4.4 Print `bash' Environment
+============================
+
+This script strips the definition of the shell functions from the
+output of the `set' Bourne-shell command.
+
+ #!/bin/sh
+
+ set | sed -n '
+ :x
+
+ # if no occurrence of "=()" print and load next line
+ /=()/! { p; b; }
+ / () $/! { p; b; }
+
+ # possible start of functions section
+ # save the line in case this is a var like FOO="() "
+ h
+
+ # if the next line has a brace, we quit because
+ # nothing comes after functions
+ n
+ /^{/ q
+
+ # print the old line
+ x; p
+
+ # work on the new line now
+ x; bx
+ '
+
+
+File: sed.info, Node: Reverse chars of lines, Next: tac, Prev: Print bash environment, Up: Examples
+
+4.5 Reverse Characters of Lines
+===============================
+
+This script can be used to reverse the position of characters in lines.
+The technique moves two characters at a time, hence it is faster than
+more intuitive implementations.
+
+ Note the `tx' command before the definition of the label. This is
+often needed to reset the flag that is tested by the `t' command.
+
+ Imaginative readers will find uses for this script. An example is
+reversing the output of `banner'.(1)
+
+ #!/usr/bin/sed -f
+
+ /../! b
+
+ # Reverse a line. Begin embedding the line between two newlines
+ s/^.*$/\
+ &\
+ /
+
+ # Move first character at the end. The regexp matches until
+ # there are zero or one characters between the markers
+ tx
+ :x
+ s/\(\n.\)\(.*\)\(.\n\)/\3\2\1/
+ tx
+
+ # Remove the newline markers
+ s/\n//g
+
+ ---------- Footnotes ----------
+
+ (1) This requires another script to pad the output of banner; for
+example
+
+ #! /bin/sh
+
+ banner -w $1 $2 $3 $4 |
+ sed -e :a -e '/^.\{0,'$1'\}$/ { s/$/ /; ba; }' |
+ ~/sedscripts/reverseline.sed

+
+4.6 Reverse Lines of Files
+==========================
+
+This one begins a series of totally useless (yet interesting) scripts
+emulating various Unix commands. This, in particular, is a `tac'
+workalike.
+
+ Note that on implementations other than GNU `sed' this script might
+easily overflow internal buffers.
+
+ #!/usr/bin/sed -nf
+
+ # reverse all lines of input, i.e. first line became last, ...
+
+ # from the second line, the buffer (which contains all previous lines)
+ # is *appended* to current line, so, the order will be reversed
+ 1! G
+
+ # on the last line we're done -- print everything
+ $ p
+
+ # store everything on the buffer again
+ h
+
+
+File: sed.info, Node: cat -n, Next: cat -b, Prev: tac, Up: Examples
+
+4.7 Numbering Lines
+===================
+
+This script replaces `cat -n'; in fact it formats its output exactly
+like GNU `cat' does.
+
+ Of course this is completely useless and for two reasons: first,
+because somebody else did it in C, second, because the following
+Bourne-shell script could be used for the same purpose and would be
+much faster:
+
+ #! /bin/sh
+ sed -e "=" $@ | sed -e '
+ s/^/ /
+ N
+ s/^ *\(......\)\n/\1 /
+ '
+
+ It uses `sed' to print the line number, then groups lines two by two
+using `N'. Of course, this script does not teach as much as the one
+presented below.
+
+ The algorithm used for incrementing uses both buffers, so the line
+is printed as soon as possible and then discarded. The number is split
+so that changing digits go in a buffer and unchanged ones go in the
+other; the changed digits are modified in a single step (using a `y'
+command). The line number for the next line is then composed and

+4.9 Counting Characters
+=======================
+
+This script shows another way to do arithmetic with `sed'. In this
+case we have to add possibly large numbers, so implementing this by
+successive increments would not be feasible (and possibly even more
+complicated to contrive than this script).
+
+ The approach is to map numbers to letters, kind of an abacus
+implemented with `sed'. `a's are units, `b's are tens and so on: we
+simply add the number of characters on the current line as units, and
+then propagate the carry to tens, hundreds, and so on.
+
+ As usual, running totals are kept in hold space.
+
+ On the last line, we convert the abacus form back to decimal. For
+the sake of variety, this is done with a loop rather than with some 80
+`s' commands(1): first we convert units, removing `a's from the number;
+then we rotate letters so that tens become `a's, and so on until no
+more letters remain.
+
+ #!/usr/bin/sed -nf
+
+ # Add n+1 a's to hold space (+1 is for the newline)
+ s/./a/g

+ x
+ s/\n/a/

+ # but they do speed up the thing

+
+4.10 Counting Words
+===================
+
+This script is almost the same as the previous one, once each of the
+words on the line is converted to a single `a' (in the previous script
+each letter was changed to an `a').
+
+ It is interesting that real `wc' programs have optimized loops for
+`wc -c', so they are much slower at counting words rather than
+characters. This script's bottleneck, instead, is arithmetic, and
+hence the word-counting one is faster (it has to manage smaller
+numbers).
+
+ Again, the common parts are not commented to show the importance of
+commenting `sed' scripts.
+
+ #!/usr/bin/sed -nf

+ # Convert words to a's

+
+4.11 Counting Lines
+===================
+
+No strange things are done now, because `sed' gives us `wc -l'
+functionality for free!!! Look:
+
+ #!/usr/bin/sed -nf
+ $=
+
+
+File: sed.info, Node: head, Next: tail, Prev: wc -l, Up: Examples
+
+4.12 Printing the First Lines
+=============================
+
+This script is probably the simplest useful `sed' script. It displays
+the first 10 lines of input; the number of displayed lines is right
+before the `q' command.
+
+ #!/usr/bin/sed -f
+ 10q
+
+
+File: sed.info, Node: tail, Next: uniq, Prev: head, Up: Examples
+
+4.13 Printing the Last Lines
+============================
+
+Printing the last N lines rather than the first is more complex but
+indeed possible. N is encoded in the second line, before the bang
+character.
+
+ This script is similar to the `tac' script in that it keeps the
+final output in the hold space and prints it at the end:
+
+ #!/usr/bin/sed -nf
+
+ 1! {; H; g; }
+ 1,10 !s/[^\n]*\n//
+ $p
+ h
+
+ Mainly, the scripts keeps a window of 10 lines and slides it by
+adding a line and deleting the oldest (the substitution command on the
+second line works like a `D' command but does not restart the loop).
+
+ The "sliding window" technique is a very powerful way to write
+efficient and complex `sed' scripts, because commands like `P' would
+require a lot of work if implemented manually.
+
+ To introduce the technique, which is fully demonstrated in the rest
+of this chapter and is based on the `N', `P' and `D' commands, here is
+an implementation of `tail' using a simple "sliding window."
+
+ This looks complicated but in fact the working is the same as the
+last script: after we have kicked in the appropriate number of lines,
+however, we stop using the hold space to keep inter-line state, and
+instead use `N' and `D' to slide pattern space by one line:
+
+ #!/usr/bin/sed -f
+
+ 1h
+ 2,10 {; H; g; }
+ $q
+ 1,9d
+ N
+ D
+
+ Note how the first, second and fourth line are inactive after the
+first ten lines of input. After that, all the script does is: exiting
+on the last line of input, appending the next input line to pattern
+space, and removing the first line.
+
+
+File: sed.info, Node: uniq, Next: uniq -d, Prev: tail, Up: Examples
+
+4.14 Make Duplicate Lines Unique
+================================
+
+This is an example of the art of using the `N', `P' and `D' commands,
+probably the most difficult to master.
+
+ #!/usr/bin/sed -f
+ h
+
+ :b
+ # On the last line, print and exit
+ $b
+ N
+ /^\(.*\)\n\1$/ {
+ # The two lines are identical. Undo the effect of
+ # the n command.
+ g
+ bb
+ }
+
+ # If the `N' command had added the last line, print and exit
+ $b
+
+ # The lines are different; print the first and go
+ # back working on the second.
+ P
+ D
+
+ As you can see, we mantain a 2-line window using `P' and `D'. This
+technique is often used in advanced `sed' scripts.
+
+
+File: sed.info, Node: uniq -d, Next: uniq -u, Prev: uniq, Up: Examples
+
+4.15 Print Duplicated Lines of Input
+====================================
+
+This script prints only duplicated lines, like `uniq -d'.
+
+ #!/usr/bin/sed -nf
+
+ $b
+ N
+ /^\(.*\)\n\1$/ {
+ # Print the first of the duplicated lines
+ s/.*\n//
+ p
+
+ # Loop until we get a different line
+ :b
+ $b
+ N
+ /^\(.*\)\n\1$/ {
+ s/.*\n//
+ bb
+ }
+ }
+
+ # The last line cannot be followed by duplicates
+ $b
+
+ # Found a different one. Leave it alone in the pattern space
+ # and go back to the top, hunting its duplicates
+ D
+
+
+File: sed.info, Node: uniq -u, Next: cat -s, Prev: uniq -d, Up: Examples
+
+4.16 Remove All Duplicated Lines
+================================
+
+This script prints only unique lines, like `uniq -u'.
+
+ #!/usr/bin/sed -f
+
+ # Search for a duplicate line --- until that, print what you find.
+ $b
+ N
+ /^\(.*\)\n\1$/ ! {
+ P
+ D
+ }
+
+ :c
+ # Got two equal lines in pattern space. At the
+ # end of the file we simply exit
+ $d
+
+ # Else, we keep reading lines with `N' until we
+ # find a different one
+ s/.*\n//
+ N
+ /^\(.*\)\n\1$/ {
+ bc
+ }
+
+ # Remove the last instance of the duplicate line
+ # and go back to the top
+ D
+
+
+File: sed.info, Node: cat -s, Prev: uniq -u, Up: Examples
+
+4.17 Squeezing Blank Lines
+==========================
+
+As a final example, here are three scripts, of increasing complexity
+and speed, that implement the same function as `cat -s', that is
+squeezing blank lines.
+
+ The first leaves a blank line at the beginning and end if there are
+some already.
+
+ #!/usr/bin/sed -f
+
+ # on empty lines, join with next
+ # Note there is a star in the regexp
+ :x
+ /^\n*$/ {
+ N
+ bx
+ }
+
+ # now, squeeze all '\n', this can be also done by:
+ # s/^\(\n\)*/\1/
+ s/\n*/\
+ /
+
+ This one is a bit more complex and removes all empty lines at the
+beginning. It does leave a single blank line at end if one was there.
+
+ #!/usr/bin/sed -f
+
+ # delete all leading empty lines
+ 1,/^./{
+ /./!d
+ }
+
+ # on an empty line we remove it and all the following
+ # empty lines, but one
+ :x
+ /./!{
+ N
+ s/^\n$//
+ tx
+ }
+
+ This removes leading and trailing blank lines. It is also the
+fastest. Note that loops are completely done with `n' and `b', without
+relying on `sed' to restart the the script automatically at the end of
+a line.
+
+ #!/usr/bin/sed -nf
+
+ # delete all (leading) blanks
+ /./!d
+
+ # get here: so there is a non empty
+ :x
+ # print it
+ p
+ # get next
+ n
+ # got chars? print it again, etc...
+ /./bx
+
+ # no, don't have chars: got an empty line
+ :z
+ # get next, if last line we finish here so no trailing
+ # empty lines are written
+ n
+ # also empty? then ignore it, and get next... this will
+ # remove ALL empty lines
+ /./!bz
+
+ # all empty lines were deleted/ignored, but we have a non empty. As
+ # what we want to do is to squeeze, insert a blank line artificially

+5 GNU `sed''s Limitations and Non-limitations
+*********************************************
+
+For those who want to write portable `sed' scripts, be aware that some
+implementations have been known to limit line lengths (for the pattern
+and hold spaces) to be no more than 4000 bytes. The POSIX standard
+specifies that conforming `sed' implementations shall support at least
+8192 byte line lengths. GNU `sed' has no built-in limit on line length;
+as long as it can `malloc()' more (virtual) memory, you can feed or
+construct lines as long as you like.
+
+ However, recursion is used to handle subpatterns and indefinite
+repetition. This means that the available stack space may limit the
+size of the buffer that can be processed by certain patterns.

+7 Reporting Bugs
+****************
+
+Email bug reports to <bonzini@gnu.org>. Be sure to include the word
+"sed" somewhere in the `Subject:' field. Also, please include the
+output of `sed --version' in the body of your report if at all possible.
+
+ Please do not send a bug report like this:
+
+ while building frobme-1.3.4
+ $ configure
+ error--> sed: file sedscr line 1: Unknown option to 's'
+
+ If GNU `sed' doesn't configure your favorite package, take a few
+extra minutes to identify the specific problem and make a stand-alone
+test case. Unlike other programs such as C compilers, making such test
+cases for `sed' is quite simple.
+
+ A stand-alone test case includes all the data necessary to perform
+the test, and the specific invocation of `sed' that causes the problem.
+The smaller a stand-alone test case is, the better. A test case should
+not involve something as far removed from `sed' as "try to configure
+frobme-1.3.4". Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+ Here are a few commonly reported bugs that are not bugs.
+
+`N' command on the last line
+ Most versions of `sed' exit without printing anything when the `N'
+ command is issued on the last line of a file. GNU `sed' prints
+ pattern space before exiting unless of course the `-n' command
+ switch has been specified. This choice is by design.
+
+ For example, the behavior of
+ sed N foo bar
+ would depend on whether foo has an even or an odd number of
+ lines(1). Or, when writing a script to read the next few lines
+ following a pattern match, traditional implementations of `sed'
+ would force you to write something like
+ /foo/{ $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N }
+ instead of just
+ /foo/{ N;N;N;N;N;N;N;N;N; }
+
+ In any case, the simplest workaround is to use `$d;N' in scripts
+ that rely on the traditional behavior, or to set the
+ `POSIXLY_CORRECT' variable to a non-empty value.
+
+Regex syntax clashes (problems with backslashes)
+ `sed' uses the POSIX basic regular expression syntax. According to
+ the standard, the meaning of some escape sequences is undefined in
+ this syntax; notable in the case of `sed' are `\|', `\+', `\?',
+ `\`', `\'', `\<', `\>', `\b', `\B', `\w', and `\W'.
+
+ As in all GNU programs that use POSIX basic regular expressions,
+ `sed' interprets these escape sequences as special characters.
+ So, `x\+' matches one or more occurrences of `x'. `abc\|def'
+ matches either `abc' or `def'.
+
+ This syntax may cause problems when running scripts written for
+ other `sed's. Some `sed' programs have been written with the
+ assumption that `\|' and `\+' match the literal characters `|' and
+ `+'. Such scripts must be modified by removing the spurious
+ backslashes if they are to be used with modern implementations of
+ `sed', like GNU `sed'.
+
+ On the other hand, some scripts use s|abc\|def||g to remove
+ occurrences of _either_ `abc' or `def'. While this worked until
+ `sed' 4.0.x, newer versions interpret this as removing the string
+ `abc|def'. This is again undefined behavior according to POSIX,
+ and this interpretation is arguably more robust: older `sed's, for
+ example, required that the regex matcher parsed `\/' as `/' in the
+ common case of escaping a slash, which is again undefined
+ behavior; the new behavior avoids this, and this is good because
+ the regex matcher is only partially under our control.
+
+ In addition, this version of `sed' supports several escape
+ characters (some of which are multi-character) to insert
+ non-printable characters in scripts (`\a', `\c', `\d', `\o', `\r',
+ `\t', `\v', `\x'). These can cause similar problems with scripts
+ written for other `sed's.
+
+`-i' clobbers read-only files
+ In short, `sed -i' will let you delete the contents of a read-only
+ file, and in general the `-i' option (*note Invocation: Invoking
+ sed.) lets you clobber protected files. This is not a bug, but
+ rather a consequence of how the Unix filesystem works.
+
+ The permissions on a file say what can happen to the data in that
+ file, while the permissions on a directory say what can happen to
+ the list of files in that directory. `sed -i' will not ever open
+ for writing a file that is already on disk. Rather, it will work
+ on a temporary file that is finally renamed to the original name:
+ if you rename or delete files, you're actually modifying the
+ contents of the directory, so the operation depends on the
+ permissions of the directory, not of the file. For this same
+ reason, `sed' does not let you use `-i' on a writeable file in a
+ read-only directory, and will break hard or symbolic links when
+ `-i' is used on such a file.
+
+`0a' does not work (gives an error)
+ There is no line 0. 0 is a special address that is only used to
+ treat addresses like `0,/RE/' as active when the script starts: if
+ you write `1,/abc/d' and the first line includes the word `abc',
+ then that match would be ignored because address ranges must span
+ at least two lines (barring the end of the file); but what you
+ probably wanted is to delete every line up to the first one
+ including `abc', and this is obtained with `0,/abc/d'.
+
+`[a-z]' is case insensitive
+ You are encountering problems with locales. POSIX mandates that
+ `[a-z]' uses the current locale's collation order - in C parlance,
+ that means using `strcoll(3)' instead of `strcmp(3)'. Some
+ locales have a case-insensitive collation order, others don't.
+
+ Another problem is that `[a-z]' tries to use collation symbols.
+ This only happens if you are on the GNU system, using GNU libc's
+ regular expression matcher instead of compiling the one supplied
+ with GNU sed. In a Danish locale, for example, the regular
+ expression `^[a-z]$' matches the string `aa', because this is a
+ single collating symbol that comes after `a' and before `b'; `ll'
+ behaves similarly in Spanish locales, or `ij' in Dutch locales.
+
+ To work around these problems, which may cause bugs in shell
+ scripts, set the `LC_COLLATE' and `LC_CTYPE' environment variables
+ to `C'.
+
+`s/.*//' does not clear pattern space
+ This happens if your input stream includes invalid multibyte
+ sequences. POSIX mandates that such sequences are _not_ matched
+ by `.', so that `s/.*//' will not clear pattern space as you would
+ expect. In fact, there is no way to clear sed's buffers in the
+ middle of the script in most multibyte locales (including UTF-8
+ locales). For this reason, GNU `sed' provides a `z' command (for
+ `zap') as an extension.
+
+ To work around these problems, which may cause bugs in shell
+ scripts, set the `LC_COLLATE' and `LC_CTYPE' environment variables
+ to `C'.

+
+Appendix A Extended regular expressions
+***************************************
+
+The only difference between basic and extended regular expressions is in
+the behavior of a few characters: `?', `+', parentheses, and braces
+(`{}'). While basic regular expressions require these to be escaped if
+you want them to behave as special characters, when using extended
+regular expressions you must escape them if you want them _to match a
+literal character_.
+
+Examples:
+`abc?'
+ becomes `abc\?' when using extended regular expressions. It
+ matches the literal string `abc?'.
+
+`c\+'
+ becomes `c+' when using extended regular expressions. It matches
+ one or more `c's.
+
+`a\{3,\}'
+ becomes `a{3,}' when using extended regular expressions. It
+ matches three or more `a's.
+
+`\(abc\)\{2,3\}'
+ becomes `(abc){2,3}' when using extended regular expressions. It
+ matches either `abcabc' or `abcabcabc'.
+
+`\(abc*\)\1'
+ becomes `(abc*)\1' when using extended regular expressions.
+ Backreferences must still be escaped when using extended regular
+ expressions.
