              GNU GENERAL PUBLIC LICENSE
                Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street,
Fifth Floor, Boston, MA  02110-1301  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 Lesser 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.

           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 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.
