- of this license document, but changing it is not allowed.
- }
-
- {\bf\large Preamble}
-\endcentered
-
-
-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.
-
-\begincentered
- {\Large \sc Terms and Conditions For Copying, Distribution and
- Modification}
-\endcentered
-
-\beginenumeration
-\item
-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.
-
-\item 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.
-
-\item
-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:
-
-\beginenumeration
-
-\item
-You must cause the modified files to carry prominent notices stating that
-you changed the files and the date of any change.
-
-\item
-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.
-
-\item
-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.)
-
-\endenumeration
-
-
-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.
-
-\item
-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:
-
-\beginenumeration
-
-\item
-
-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,
-
-\item
-
-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,
-
-\item
-
-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.)
-
-\endenumeration
-
-
-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.
-
-\item
-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.
-
-\item
-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.
-
-\item
-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.
-
-\item
-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.
-
-\item
-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.
-
-\item
-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.
-
-\item
-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.

-{\sc Because the program is licensed free of charge, there is no warranty

-\fakesection {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 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.
-
-\beginnarrower
- one line to give the program's name and a brief idea of what it does. \\

-
- 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

- You should have received a copy of the GNU General Public License

- Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
-\endnarrower
-
-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 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.
-\endnarrower
-
-
-The hypothetical commands {\tt show w} and {\tt show c} should show the
-appropriate parts of the General Public License. Of course, the commands
-you use may be called something other than {\tt show w} and {\tt 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:
