+ later version, or
+b) the "Artistic License"
+
+--- The GNU General Public License, Version 1, February 1989 ---
+
+This software is Copyright (c) 1996 by Kenneth Albanowski.
+
+This is free software, licensed under:
+
+ The GNU General Public License, Version 1, February 1989
+
+ GNU GENERAL PUBLIC LICENSE
+ Version 1, February 1989
+
+ Copyright (C) 1989 Free Software Foundation, Inc.
+ 51 Franklin St, Suite 500, Boston, MA 02110-1335 USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The license agreements of most software companies try to keep users
+at the mercy of those companies. By contrast, our 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. The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, 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 a 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 tell them 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.
+
+ 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 Agreement 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 work containing the
+Program or a portion of it, either verbatim or with modifications. Each
+licensee is addressed as "you".
+
+ 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
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program. You may charge a fee for the physical act of
+transferring a copy.
+
+ 2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+ a) cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change; and
+
+ b) cause the whole of any work that you distribute or publish, that
+ in whole or in part contains the Program or any part thereof, either
+ with or without modifications, to be licensed at no charge to all
+ third parties under the terms of this General Public License (except
+ that you may choose to grant warranty protection to some or all
+ third parties, at your option).
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the simplest and most usual 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 General
+ Public License.
+
+ d) 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.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+ 3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 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
+ Paragraphs 1 and 2 above; or,
+
+ b) accompany it with a written offer, valid for at least three
+ years, to give any third party free (except for a nominal charge
+ for the cost of distribution) a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ c) accompany it with the information you received as to where the
+ corresponding source code may be obtained. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it. For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+ 4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License. However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+ 5. By copying, distributing or modifying 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.
+
+ 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.
+
+ 7. 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 the 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
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+ 8. 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
+
+ 9. 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.
+
+ 10. 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
+
+ Appendix: 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 humanity, 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) 19yy <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 1, 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., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 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) 19xx 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 a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ program `Gnomovision' (a program to direct compilers to make passes
+ at assemblers) written by James Hacker.

+
+The Artistic License
+
+Preamble
+
+The intent of this document is to state the conditions under which a Package
+may be copied, such that the Copyright Holder maintains some semblance of
+artistic control over the development of the package, while giving the users of
+the package the right to use and distribute the Package in a more-or-less
+customary fashion, plus the right to make reasonable modifications.
+
+Definitions:
+
+ - "Package" refers to the collection of files distributed by the Copyright
+ Holder, and derivatives of that collection of files created through
+ textual modification.
+ - "Standard Version" refers to such a Package if it has not been modified,
+ or has been modified in accordance with the wishes of the Copyright
+ Holder.
+ - "Copyright Holder" is whoever is named in the copyright or copyrights for
+ the package.
+ - "You" is you, if you're thinking about copying or distributing this Package.
+ - "Reasonable copying fee" is whatever you can justify on the basis of media
+ cost, duplication charges, time of people involved, and so on. (You will
+ not be required to justify it to the Copyright Holder, but only to the
+ computing community at large as a market that must bear the fee.)
+ - "Freely Available" means that no fee is charged for the item itself, though
+ there may be fees involved in handling the item. It also means that
+ recipients of the item may redistribute it under the same conditions they
+ received it.
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you
+duplicate all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications derived
+from the Public Domain or from the Copyright Holder. A Package modified in such
+a way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided that
+you insert a prominent notice in each changed file stating how and when you
+changed that file, and provided that you do at least ONE of the following:
+
+ a) place your modifications in the Public Domain or otherwise make them
+ Freely Available, such as by posting said modifications to Usenet or an
+ equivalent medium, or placing the modifications on a major archive site
+ such as ftp.uu.net, or by allowing the Copyright Holder to include your
+ modifications in the Standard Version of the Package.
+
+ b) use the modified Package only within your corporation or organization.
+
+ c) rename any non-standard executables so the names do not conflict with
+ standard executables, which must also be provided, and provide a separate
+ manual page for each non-standard executable that clearly documents how it
+ differs from the Standard Version.
+
+ d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or executable
+form, provided that you do at least ONE of the following:
+
+ a) distribute a Standard Version of the executables and library files,
+ together with instructions (in the manual page or equivalent) on where to
+ get the Standard Version.
+
+ b) accompany the distribution with the machine-readable source of the Package
+ with your modifications.
+
+ c) accompany any non-standard executables with their corresponding Standard
+ Version executables, giving the non-standard executables non-standard
+ names, and clearly documenting the differences in manual pages (or
+ equivalent), together with instructions on where to get the Standard
+ Version.
+
+ d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this
+Package. You may charge any fee you choose for support of this Package. You
+may not charge a fee for this Package itself. However, you may distribute this
+Package in aggregate with other (possibly commercial) programs as part of a
+larger (possibly commercial) software distribution provided that you do not
+advertise this Package as a product of your own.
+
+6. The scripts and library files supplied as input to or produced as output
+from the programs of this Package do not automatically fall under the copyright
+of this Package, but belong to whomever generated them, and may be sold
+commercially, and may be aggregated with this Package.
+
+7. C or perl subroutines supplied by you and linked into this Package shall not
+be considered part of this Package.
+
+8. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.
+
+9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
+WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
+MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

- Sort::Versions - a perl 5 module for sorting of revision (and similar)
- numbers
-
-This module allows easy sorting (via comparisons) of mixed text and numeric
-strings, similar to the complex "version numbers" that many revision control
-packages and shared library systems use. For an explanation of the
-algorithm, it's easiest to look at these examples:
-
- 1.1 < 1.2
- 1.1a < 1.2
- 1.1 < 1.1.1

-To install, unpack the tarball and say:
-
- perl Makefile.PL
- make
- make test
-
-If the tests are successful, say as root:
-
- make install
-
-And that's it. Further documentation is available in the Versions.pm file,
-which may be accessed via 'perldoc Sort::Versions' after installation.
-
-* Changes in this release
-
-This is version 1.5; there are no functional changes since the last
-version but some tidying and extra tests.

-=head1 NAME
-
-Sort::Versions - a perl 5 module for sorting of revision-like numbers
-
-=head1 SYNOPSIS
-
- use Sort::Versions;
- @l = sort { versioncmp($a, $b) } qw( 1.2 1.2.0 1.2a.0 1.2.a 1.a 02.a );
-
- ...
-
- use Sort::Versions;
- print 'lower' if versioncmp('1.2', '1.2a') == -1;
-
- ...
-
- use Sort::Versions;
- %h = (1 => 'd', 2 => 'c', 3 => 'b', 4 => 'a');
- @h = sort { versioncmp($h{$a}, $h{$b}) } keys %h;
-
-=head1 DESCRIPTION
-
-Sort::Versions allows easy sorting of mixed non-numeric and numeric strings,
-like the 'version numbers' that many shared library systems and revision
-control packages use. This is quite useful if you are trying to deal with
-shared libraries. It can also be applied to applications that intersperse
-variable-width numeric fields within text. Other applications can
-undoubtedly be found.
-
-For an explanation of the algorithm, itE<39>s simplest to look at these examples:
-
- 1.1 < 1.2
- 1.1a < 1.2
- 1.1 < 1.1.1
- 1.1 < 1.1a
- 1.1.a < 1.1a
- 1 < a
- a < b
- 1 < 2
- 1.1-3 < 1.1-4
- 1.1-5 < 1.1.6
-
-More precisely (but less comprehensibly), the two strings are treated
-as subunits delimited by periods or hyphens. Each subunit can contain
-any number of groups of digits or non-digits. If digit groups are
-being compared on both sides, a numeric comparison is used, otherwise
-a ASCII ordering is used. A group or subgroup with more units will win
-if all comparisons are equal. A period binds digit groups together
-more tightly than a hyphen.
-
-Some packages use a different style of version numbering: a simple
-real number written as a decimal. Sort::Versions has limited support
-for this style: when comparing two subunits which are both digit
-groups, if either subunit has a leading zero, then both are treated
-like digits after a decimal point. So for example:
-
- 0002 < 1
- 1.06 < 1.5
-
-This wonE<39>t always work, because there wonE<39>t always be a leading zero
-in real-number style version numbers. There is no way for
-Sort::Versions to know which style was intended. But a lot of the time
-it will do the right thing. If you are making up version numbers, the
-style with (possibly) more than one dot is the style to use.
-
-=head1 USAGE
-
-The function C<versioncmp()> takes two arguments and compares them like C<cmp>.
-With perl 5.6 or later, you can also use this function directly in sorting:
-
- @l = sort versioncmp qw(1.1 1.2 1.0.3);
-
-The function C<versions()> can be used directly as a sort function even on
-perl 5.005 and earlier, but its use is deprecated.
