DESCRIPTION
       GNU GENERAL PUBLIC LICENSE

       Version 2, June 1991

	       Copyright (c) 1989, 1991 Free Software Foundation, Inc.
	       59 Temple Place - Suite 330, Boston, MA 02111-1307, 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 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 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 Pro‐
	   gram).  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 conspicu‐
	   ously and appropriately publish on each copy an appropriate copy‐
	   right notice and disclaimer of warranty; keep intact all the
	   notices that refer to this License and to the absence of any war‐
	   ranty; 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 distrib‐
	   ute 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 pro‐
	       vide 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 interac‐
	       tive but does not normally print such an announcement, your
	       work based on the Program is not required to print an announce‐
	       ment.)

	   These requirements apply to the modified work as a whole.  If iden‐
	   tifiable 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 con‐
	   test your rights to work written entirely by you; rather, the
	   intent is to exercise the right to control the distribution of de‐
	   rivative or collective works based on the Program.

	   In addition, mere aggregation of another work not based on the Pro‐
	   gram 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 fol‐
	   lowing:

	   a.  Accompany it with the complete corresponding machine-readable
	       source code, which must be distributed under the terms of Sec‐
	       tions 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 dis‐
	   tribution 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 oth‐
	   erwise 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.  There‐
	   fore, 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 obliga‐
	   tions, 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 cer‐
	   tain 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 incorpo‐
	   rates the limitation as if written in the body of this License.

       9.  The Free Software Foundation may publish revised and/or new ver‐
	   sions 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 Pro‐
	   gram 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 ver‐
	   sion 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 Founda‐
	   tion; we sometimes make exceptions for this.	 Our decision will be
	   guided by the two goals of preserving the free status of all deriv‐
	   atives 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 WAR‐
	   RANTY 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 LIM‐
	   ITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
	   A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PER‐
	   FORMANCE 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 WRIT‐
	   ING 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 CON‐
	   SEQUENTIAL 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) <year>  <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., 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 applica‐
       tions with the library.	If this is what you want to do, use the GNU
       Library General Public License instead of this License.
