+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) 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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+ 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
+convey 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 2 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, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This 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 Library General
+Public License instead of this License.

+cvs-mailcommit - Send CVS commitments via mail
+
+=head1 SYNOPSIS
+
+B<cvs-mailcommit> [options] [version*]
+
+=head1 DESCRIPTION
+
+B<cvs-mailcommit> is a helper application to CVS to help people keep
+track of CVS repositories via mail. It is hooked into the CVS system
+via the B<CVSROOT>/I<loginfo> file. It will read modification
+information from CVS via B<stdin> and require version information via
+the commandline.
+
+B<cvs-mailcommit> will send differences of modified files or entire
+new files via mail to the denoted address.
+
+You'll have to hook it into CVS for each module in a repository that
+you want to monitor via mail. See B<INSTALLATION> below

+
+=head1 OPTIONS
+
+This program supports the following arguments. When the arguments
+don't make sense the program won't do anything.
+
+=over 6
+
+=item B<-m> I<address>, B<--mailto> I<address>
+
+Send the mail to the specified I<address>. This option can be
+specified on the commandline multiple times.
+
+=item B<--diff>
+
+Generate unified diffs for all modified files.
+
+=item B<--full>
+
+Include the entire fill for newly created files that were added to the
+repository.
+
+=item B<--maxlines> I<nnn>
+
+You can specify how many lines per file may be quoted in the resulting
+mail. Limiting the number of quoted lines may be useful for
+repositories with excessive changes that are similar. The default is
+to copy 400 lines.
+
+=item B<--xloop> I<address>
+
+Include a special B<X-Loop> header in the generated mail. This is
+intended for users to be able to filter CVS mails by a common header
+line. The line will look like
+
+X-Loop: I<address>
+
+=item B<--from> I<address>
+
+Generate a B<From:>-line of the form
+
+From: CVS User foo <I<address>>
+
+Otherwise the local user the program runs under will be used instead
+of I<address>. With this parameter you can ensure that all such mails
+will be sent with the same from line, which may be useful for
+moderated lists or some where only subscribers may write.
+
+=item B<--replyto> I<address>
+
+Try to redirect replies to CVS mails to another address by setting
+proper header lines such as
+
+Reply-To: I<address>
+
+Mail-Followup-To: I<address>
+
+=item B<--approved> I<address>
+
+Include a special B<Approved:>-line in the mail. This header is
+intended for moderated mailing-lists to pass the SmartList moderation
+mechanism. The created header will look like
+
+Approved: I<address>
+
+=item B<--cvs> I<version string>
+
+This option carries the CVS version info from CVS into the program.
+It will be added automatically by CVS. When installing this program
+into the B<loginfo> file of a CVS repository, you will need to add the
+following option:
+
+B<--cvs> %{sVv}
+
+If you want to test this program manually you'll have to supply the
+module directory and the modified files including the old and new
+versions. This will look like
+
+--cvs 'CVSROOT loginfo,1.1,1.2'
+
+This option is only usful for old-style CVS format strings (i.e. prior
+to CVS 1.12.6). You can continue using old-style format strings with
+newer cvs if you write %1{sVv} and set B<UseNewInfoFmtStrings>=I<yes>
+in CVSROOT/config. For more recent versions of CVS you should,
+however, use the new --root and --dir arguments and place %{sVv} at
+the end of the commandline.
+
+=item B<--root> I<cvs repository>
+
+Specify the CVS repository directory. This is normally done by the
+CVS server. Prior to version 1.12 the repository was transmitted to
+the log processor via the B<CVSROOT> environment variable. The
+parameter to this option is normally filled in by CVS using the %r
+format string:
+
+B<--root> %r
+
+=item B<--dir> I<module directory>
+
+Specify the directory within the CVS repository in which directories
+or file were added or modified. The parameter to this option is
+normally filled in by CVS using the %p format string:
+
+B<--dir> %p
+

+=head1 CONFIGURATION FILE
+
+B<cvs-mailcommit> supports an additional configuration file
+I</etc/cvs-mailcommit.pl> so that hard-coded default values can be
+overwritten. The file is included via require and hence needs to
+contain valid Perl code, which evaluates to I<true>. I.e. place B<1;>
+at the end of the file.
+
+=head1 INSTALLATION
+
+The B<CVSROOT>/I<loginfo> file controls where B<cvs commit> log
+information is sent. The first entry on a line is a regular
+expression which must match the directory (alias module) that the
+change is being made to, relative to the $B<CVSROOT>. If a match is
+found, then the remainder of the line is a filter program that should
+expect log information on its standard input.
+
+A I<loginfo> line looks like
+
+<directory> <command> --<option> --<option>
+
+=head1 NOTES
+
+The B<--cvs> option is only valid for old-style CVS format strings
+prior to version 1.12.6 of CVS with I<%{sVv}> or for new-style CVS
+format strings using the compatibility hack with I<%1{sVv}>.
+
+For new-style CVS format strings for CVS version 1.12.6 or higher
+B<--cvs> must not be used anymore, but instead B<--root> and B<--dir>
+are required. The version information I<%{sVv}> must be added at the
+end of the command line.
+
+=head1 EXAMPLE
+
+Assume you want to monitor changes in the B<CVSROOT> module, then you
+may want to use the following line.
+
+ CVSROOT cvs-mailcommit \
+ --mailto master@host.org \
+ --from cvs@cvshost.com \
+ --cvs %{sVv} --diff --full
+
+If you want to distribute changes in a module via a mailing list where
+only these log messages should appear you may have to add an X-Loop:
+or Approved: header line.
+
+ webwml cvs-mailcommit \
+ --mailto master@host.org \
+ --from cvs@cvshost.com \
+ --approved cvsmaster@cvshost.com \
+ --cvs %{sVv} --diff --full
+
+The above configuration lines are valid only for old-style format
+strings. With a more recent version of CVS (1.12.6 or newer) you'll
+have to replace I<%{sVv}> with I<%1{sVv}> and set
+B<UseNewInfoFmtStrings> to I<yes> in I<CVSROOT/config>.
+
+For new-style CVS format strings other parameters need to be used
+since CVS changed the syntax and semantics. You must not use the
+B<--cvs> option anymore but need to use B<--root> and B<--dir> and
+place the version list at the end. The last example converted for
+new-style format strings looks like the following:
+
+ webwml cvs-mailcommit \
+ --mailto master@host.org \
+ --from cvs@cvshost.com \
+ --approved cvsmaster@cvshost.com \
+ --diff --full --root %r --dir %p %{sVv}
+
+To improve readability, the above lines were broken up into several
+lines using normal continuation lines. This is not supported by CVS.
+You will have to write it in one single line.
+
+=head1 WARNING
+
+CVS does not support continuation lines (multiple lines per command)
+in the B<CVSROOT>/I<loginfo> file. You'll have to write each filter
+in a single line of its own.
