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.

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)  

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.

"CLASSPATH" EXCEPTION TO THE GPL VERSION 2

Certain source files distributed by Sun Microsystems, Inc. are subject to
the following clarification and special exception to the GPL Version 2,
but only where Sun has expressly included in the particular source file's
header the words "Sun designates this particular file as subject to the
"Classpath" exception as provided by Sun in the License file that
accompanied this code."

 Linking this library statically or dynamically with other modules is
making a combined work based on this library. Thus, the terms and
conditions of the GNU General Public License Version 2 cover the whole
combination.

 As a special exception, the copyright holders of this library give you
permission to link this library with independent modules to produce an
executable, regardless of the license terms of these independent modules,
and to copy and distribute the resulting executable under terms of your
choice, provided that you also meet, for each linked independent module,
the terms and conditions of the license of that module. An independent
module is a module which is not derived from or based on this library. If
you modify this library, you may extend this exception to your version of
the library, but you are not obligated to do so. If you do not wish to do
so, delete this exception statement from your version.
