                    GNU GENERAL PUBLIC LICENSE
                       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.

 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. 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.

                            TERMS AND CONDITIONS

 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.

 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.

 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 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.

 3. You may copy and distribute the Program 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.
   b) Accompany it with a written offer, valid for at least three years,
      to give any third party the complete corresponding source code.

 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. THE PROGRAM
 IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.

 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ANY COPYRIGHT
 HOLDER BE LIABLE FOR DAMAGES ARISING OUT OF THE USE OF THE PROGRAM.

                     END OF TERMS AND CONDITIONS
