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.

Terms and Conditions
-------------------

0. Definitions.

"This License" refers to version 2 of the GNU General Public License.

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.

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.)

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; 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.)

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.

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 from you, then the only way you could satisfy both it
   and this License would be to refrain entirely from distribution
   of the Program.

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.

10. 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.

11. 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.

12. DISCLAIMER OF WARRANTY

THE PROGRAM IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
OF THIRD PARTY RIGHTS. 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.
