-- <title>GNU General Public License</title>
-- <section id="gpl-1">
-- <title>Preamble</title>
-- <para>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.</para>
--
-- <para>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.</para>
--
-- <para>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.</para>
--
-- <para>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.</para>
--
-- <para>We protect your rights with two steps:
-- <orderedlist>
-- <listitem>
-- <para>copyright the software, and</para>
-- </listitem>
-- <listitem>
-- <para>offer you this license which gives you legal permission to copy,
-- distribute and/or modify the software.</para>
-- </listitem>
-- </orderedlist>
-- </para>
--
-- <para>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.</para>
--
-- <para>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.</para>
--
-- <para>The precise terms and conditions for copying, distribution and modification
-- follow.</para>
-- </section>
-- <section id="gpl-2">
-- <title>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</title>
-- <section id="gpl-2-0">
-- <title>Section 0</title>
-- <para>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 <quote>Program</quote>, below, refers to any such
-- program or work, and a
-- <quote>work based on the Program</quote> 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
-- <quote>modification</quote>.) Each licensee is addressed as <quote>you</quote>.</para>
--
-- <para>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.</para>
-- </section>
-- <section id="gpl-2-1">
-- <title>Section 1</title>
-- <para>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.</para>
--
-- <para>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.</para>

-- <section id="gpl-2-2">
-- <title>Section 2</title>
-- <para>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
-- <link linkend="gpl-2-1">Section 1</link> above, provided
-- that you also meet all of these conditions:
-- <orderedlist numeration="loweralpha">
-- <listitem>
-- <para>You must cause the modified files to carry prominent notices stating that
-- you changed the files and the date of any change.</para>
-- </listitem>
-- <listitem>
-- <para>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.</para>
-- </listitem>
-- <listitem>
-- <para>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.)</para>
-- </listitem>
-- </orderedlist>
-- </para>
--
-- <para>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.</para>
--
-- <para>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.</para>
--
-- <para>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.</para>

-- 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.</para>
--
-- <para>If distribution of executable or object code is made by offering access to copy from a

-- <para>You may not copy, modify, sublicense, or distribute the Program except as expressly provided

-- <title>Section 6</title>

-- <title>Section 7</title>
-- <para>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.</para>

--
-- <para>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

-- 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
