		    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.
