       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 free-
       dom 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  free-
       dom,  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 modi-
       fied 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

GPL(GNU)             Free Software Foundation            GPL(GNU)


       original authors' reputations.

       Finally, any free  program  is  threatened  constantly  by
       software patents.  We wish to avoid the danger that redis-
       tributors 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.

                       GNU GENERAL PUBLIC LICENSE
       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 trans-
       lated 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 modifica-
       tion 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 (indepen-
       dent 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 Pro-
       gram's source code as you receive it, in any medium,  pro-
       vided  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 protec-
       tion 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 Pro-
       gram, 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  pub-
           lish,  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 inter-
           actively  when  run,  you  must cause it, when started



GNU                            GPL                              3





GPL(GNU)             Free Software Foundation            GPL(GNU)


           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  Pro-
           gram 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 dis-
       tribute 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  cus-
           tomarily 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  customar-
           ily used for software interchange; or,

       c)  Accompany  it  with the information you received as to



GNU                            GPL                              4





GPL(GNU)             Free Software Foundation            GPL(GNU)


           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  compi-
       lation  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  (com-
       piler, kernel, and so on) of the operating system on which
       the executable runs, unless that component itself accompa-
       nies 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  dis-
       tribute the Program is void, and will automatically termi-
       nate 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 per-
       mission to modify or distribute the Program or its deriva-
       tive works.  These actions are prohibited by law if you do
       not  accept this License.  Therefore, by modifying or dis-
       tributing 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.
