GNU GENERAL PUBLIC LICENSE
**************************

                        Version 2, June 1991

    Copyright (C) 1989, 1991 Free Software Foundation, Inc.
    675 Mass Ave, Cambridge, MA 02139, 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.

   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 AN 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 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., 675 Mass Ave, Cambridge, MA 02139, 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) 19YY 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.
