 Everyone is permitted to copy and distribute verbatim copies
acfbd3
 of this license document, but changing it is not allowed.
acfbd3
acfbd3
                            Preamble
acfbd3
acfbd3
  The licenses for most software are designed to take away your
acfbd3
freedom to share and change it.  By contrast, the GNU General Public
acfbd3
License is intended to guarantee your freedom to share and change free
acfbd3
software--to make sure the software is free for all its users.  This
acfbd3
General Public License applies to most of the Free Software
acfbd3
Foundation's software and to any other program whose authors commit to
acfbd3
using it.  (Some other Free Software Foundation software is covered by
acfbd3
the GNU Lesser General Public License instead.)  You can apply it to
acfbd3
your programs, too.
acfbd3
acfbd3
  When we speak of free software, we are referring to freedom, not
acfbd3
price.  Our General Public Licenses are designed to make sure that you
acfbd3
have the freedom to distribute copies of free software (and charge for
acfbd3
this service if you wish), that you receive source code or can get it
acfbd3
if you want it, that you can change the software or use pieces of it
acfbd3
in new free programs; and that you know you can do these things.
acfbd3
acfbd3
  To protect your rights, we need to make restrictions that forbid
acfbd3
anyone to deny you these rights or to ask you to surrender the rights.
acfbd3
These restrictions translate to certain responsibilities for you if you
acfbd3
distribute copies of the software, or if you modify it.
acfbd3
acfbd3
  For example, if you distribute copies of such a program, whether
acfbd3
gratis or for a fee, you must give the recipients all the rights that
acfbd3
you have.  You must make sure that they, too, receive or can get the
acfbd3
source code.  And you must show them these terms so they know their
acfbd3
rights.
acfbd3
acfbd3
  We protect your rights with two steps: (1) copyright the software, and
acfbd3
(2) offer you this license which gives you legal permission to copy,
acfbd3
distribute and/or modify the software.
acfbd3
acfbd3
  Also, for each author's protection and ours, we want to make certain
acfbd3
that everyone understands that there is no warranty for this free
acfbd3
software.  If the software is modified by someone else and passed on, we
acfbd3
want its recipients to know that what they have is not the original, so
acfbd3
that any problems introduced by others will not reflect on the original
acfbd3
authors' reputations.
acfbd3
acfbd3
  Finally, any free program is threatened constantly by software
acfbd3
patents.  We wish to avoid the danger that redistributors of a free
acfbd3
program will individually obtain patent licenses, in effect making the
acfbd3
program proprietary.  To prevent this, we have made it clear that any
acfbd3
patent must be licensed for everyone's free use or not licensed at all.
acfbd3
acfbd3
  The precise terms and conditions for copying, distribution and
acfbd3
modification follow.

                    GNU GENERAL PUBLIC LICENSE
acfbd3
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
acfbd3
acfbd3
  0. This License applies to any program or other work which contains
acfbd3
a notice placed by the copyright holder saying it may be distributed
acfbd3
under the terms of this General Public License.  The "Program", below,
acfbd3
refers to any such program or work, and a "work based on the Program"
acfbd3
means either the Program or any derivative work under copyright law:
acfbd3
that is to say, a work containing the Program or a portion of it,
acfbd3
either verbatim or with modifications and/or translated into another
acfbd3
language.  (Hereinafter, translation is included without limitation in
acfbd3
the term "modification".)  Each licensee is addressed as "you".
acfbd3
acfbd3
Activities other than copying, distribution and modification are not
acfbd3
covered by this License; they are outside its scope.  The act of
acfbd3
running the Program is not restricted, and the output from the Program
acfbd3
is covered only if its contents constitute a work based on the
acfbd3
Program (independent of having been made by running the Program).
acfbd3
Whether that is true depends on what the Program does.
acfbd3
acfbd3
  1. You may copy and distribute verbatim copies of the Program's
acfbd3
source code as you receive it, in any medium, provided that you
acfbd3
conspicuously and appropriately publish on each copy an appropriate
acfbd3
copyright notice and disclaimer of warranty; keep intact all the
acfbd3
notices that refer to this License and to the absence of any warranty;
acfbd3
and give any other recipients of the Program a copy of this License
acfbd3
along with the Program.
acfbd3
acfbd3
You may charge a fee for the physical act of transferring a copy, and
acfbd3
you may at your option offer warranty protection in exchange for a fee.
acfbd3
acfbd3
  2. You may modify your copy or copies of the Program or any portion
acfbd3
of it, thus forming a work based on the Program, and copy and
acfbd3
distribute such modifications or work under the terms of Section 1
acfbd3
above, provided that you also meet all of these conditions:
acfbd3
acfbd3
    a) You must cause the modified files to carry prominent notices
acfbd3
    stating that you changed the files and the date of any change.
acfbd3
acfbd3
    b) You must cause any work that you distribute or publish, that in
acfbd3
    whole or in part contains or is derived from the Program or any
acfbd3
    part thereof, to be licensed as a whole at no charge to all third
acfbd3
    parties under the terms of this License.
acfbd3
acfbd3
    c) If the modified program normally reads commands interactively
acfbd3
    when run, you must cause it, when started running for such
acfbd3
    interactive use in the most ordinary way, to print or display an
acfbd3
    announcement including an appropriate copyright notice and a
acfbd3
    notice that there is no warranty (or else, saying that you provide
acfbd3
    a warranty) and that users may redistribute the program under
acfbd3
    these conditions, and telling the user how to view a copy of this
acfbd3
    License.  (Exception: if the Program itself is interactive but
acfbd3
    does not normally print such an announcement, your work based on
acfbd3
    the Program is not required to print an announcement.)
acfbd3
acfbd3
These requirements apply to the modified work as a whole.  If
acfbd3
identifiable sections of that work are not derived from the Program,
acfbd3
and can be reasonably considered independent and separate works in
acfbd3
themselves, then this License, and its terms, do not apply to those
acfbd3
sections when you distribute them as separate works.  But when you
acfbd3
distribute the same sections as part of a whole which is a work based
acfbd3
on the Program, the distribution of the whole must be on the terms of
acfbd3
this License, whose permissions for other licensees extend to the
acfbd3
entire whole, and thus to each and every part regardless of who wrote it.
acfbd3
acfbd3
Thus, it is not the intent of this section to claim rights or contest
acfbd3
your rights to work written entirely by you; rather, the intent is to
acfbd3
exercise the right to control the distribution of derivative or
acfbd3
collective works based on the Program.
acfbd3
acfbd3
In addition, mere aggregation of another work not based on the Program
acfbd3
with the Program (or with a work based on the Program) on a volume of
acfbd3
a storage or distribution medium does not bring the other work under
acfbd3
the scope of this License.
acfbd3
acfbd3
  3. You may copy and distribute the Program (or a work based on it,
acfbd3
under Section 2) in object code or executable form under the terms of
acfbd3
Sections 1 and 2 above provided that you also do one of the following:
acfbd3
acfbd3
    a) Accompany it with the complete corresponding machine-readable
acfbd3
    source code, which must be distributed under the terms of Sections
acfbd3
    1 and 2 above on a medium customarily used for software interchange; or,
acfbd3
acfbd3
    b) Accompany it with a written offer, valid for at least three
acfbd3
    years, to give any third party, for a charge no more than your
acfbd3
    cost of physically performing source distribution, a complete
acfbd3
    machine-readable copy of the corresponding source code, to be
acfbd3
    distributed under the terms of Sections 1 and 2 above on a medium
acfbd3
    customarily used for software interchange; or,
acfbd3
acfbd3
    c) Accompany it with the information you received as to the offer
acfbd3
    to distribute corresponding source code.  (This alternative is
acfbd3
    allowed only for noncommercial distribution and only if you
acfbd3
    received the program in object code or executable form with such
acfbd3
    an offer, in accord with Subsection b above.)
acfbd3
acfbd3
The source code for a work means the preferred form of the work for
acfbd3
making modifications to it.  For an executable work, complete source
acfbd3
code means all the source code for all modules it contains, plus any
acfbd3
associated interface definition files, plus the scripts used to
acfbd3
control compilation and installation of the executable.  However, as a
acfbd3
special exception, the source code distributed need not include
acfbd3
anything that is normally distributed (in either source or binary
acfbd3
form) with the major components (compiler, kernel, and so on) of the
acfbd3
operating system on which the executable runs, unless that component
acfbd3
itself accompanies the executable.
acfbd3
acfbd3
If distribution of executable or object code is made by offering
acfbd3
access to copy from a designated place, then offering equivalent
acfbd3
access to copy the source code from the same place counts as
acfbd3
distribution of the source code, even though third parties are not
acfbd3
compelled to copy the source along with the object code.
acfbd3
acfbd3
  4. You may not copy, modify, sublicense, or distribute the Program
acfbd3
except as expressly provided under this License.  Any attempt
acfbd3
otherwise to copy, modify, sublicense or distribute the Program is
acfbd3
void, and will automatically terminate your rights under this License.
acfbd3
However, parties who have received copies, or rights, from you under
acfbd3
this License will not have their licenses terminated so long as such
acfbd3
parties remain in full compliance.
acfbd3
acfbd3
  5. You are not required to accept this License, since you have not
acfbd3
signed it.  However, nothing else grants you permission to modify or
acfbd3
distribute the Program or its derivative works.  These actions are
acfbd3
prohibited by law if you do not accept this License.  Therefore, by
acfbd3
modifying or distributing the Program (or any work based on the
acfbd3
Program), you indicate your acceptance of this License to do so, and
acfbd3
all its terms and conditions for copying, distributing or modifying
acfbd3
the Program or works based on it.
acfbd3
acfbd3
  6. Each time you redistribute the Program (or any work based on the
acfbd3
Program), the recipient automatically receives a license from the
acfbd3
original licensor to copy, distribute or modify the Program subject to
acfbd3
these terms and conditions.  You may not impose any further
acfbd3
restrictions on the recipients' exercise of the rights granted herein.
acfbd3
You are not responsible for enforcing compliance by third parties to
acfbd3
this License.
acfbd3
acfbd3
  7. If, as a consequence of a court judgment or allegation of patent
acfbd3
infringement or for any other reason (not limited to patent issues),
acfbd3
conditions are imposed on you (whether by court order, agreement or
acfbd3
otherwise) that contradict the conditions of this License, they do not
acfbd3
excuse you from the conditions of this License.  If you cannot
acfbd3
distribute so as to satisfy simultaneously your obligations under this
acfbd3
License and any other pertinent obligations, then as a consequence you
acfbd3
may not distribute the Program at all.  For example, if a patent
acfbd3
license would not permit royalty-free redistribution of the Program by
acfbd3
all those who receive copies directly or indirectly through you, then
acfbd3
the only way you could satisfy both it and this License would be to
acfbd3
refrain entirely from distribution of the Program.
acfbd3
acfbd3
If any portion of this section is held invalid or unenforceable under
acfbd3
any particular circumstance, the balance of the section is intended to
acfbd3
apply and the section as a whole is intended to apply in other
acfbd3
circumstances.
acfbd3
acfbd3
It is not the purpose of this section to induce you to infringe any
acfbd3
patents or other property right claims or to contest validity of any
acfbd3
such claims; this section has the sole purpose of protecting the
acfbd3
integrity of the free software distribution system, which is
acfbd3
implemented by public license practices.  Many people have made
acfbd3
generous contributions to the wide range of software distributed
acfbd3
through that system in reliance on consistent application of that
acfbd3
system; it is up to the author/donor to decide if he or she is willing
acfbd3
to distribute software through any other system and a licensee cannot
acfbd3
impose that choice.
acfbd3
acfbd3
This section is intended to make thoroughly clear what is believed to
acfbd3
be a consequence of the rest of this License.
acfbd3
acfbd3
  8. If the distribution and/or use of the Program is restricted in
acfbd3
certain countries either by patents or by copyrighted interfaces, the
acfbd3
original copyright holder who places the Program under this License
acfbd3
may add an explicit geographical distribution limitation excluding
acfbd3
those countries, so that distribution is permitted only in or among
acfbd3
countries not thus excluded.  In such case, this License incorporates
acfbd3
the limitation as if written in the body of this License.
acfbd3
acfbd3
  9. The Free Software Foundation may publish revised and/or new versions
acfbd3
of the General Public License from time to time.  Such new versions will
acfbd3
be similar in spirit to the present version, but may differ in detail to
acfbd3
address new problems or concerns.
acfbd3
acfbd3
Each version is given a distinguishing version number.  If the Program
acfbd3
specifies a version number of this License which applies to it and "any
acfbd3
later version", you have the option of following the terms and conditions
acfbd3
either of that version or of any later version published by the Free
acfbd3
Software Foundation.  If the Program does not specify a version number of
acfbd3
this License, you may choose any version ever published by the Free Software
acfbd3
Foundation.
acfbd3
acfbd3
  10. If you wish to incorporate parts of the Program into other free
acfbd3
programs whose distribution conditions are different, write to the author
acfbd3
to ask for permission.  For software which is copyrighted by the Free
acfbd3
Software Foundation, write to the Free Software Foundation; we sometimes
acfbd3
make exceptions for this.  Our decision will be guided by the two goals
acfbd3
of preserving the free status of all derivatives of our free software and
acfbd3
of promoting the sharing and reuse of software generally.
acfbd3
acfbd3
                            NO WARRANTY
acfbd3
acfbd3
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
acfbd3
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
acfbd3
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
acfbd3
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
acfbd3
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
acfbd3
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
acfbd3
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
acfbd3
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
acfbd3
REPAIR OR CORRECTION.
acfbd3
acfbd3
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
acfbd3
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
acfbd3
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
acfbd3
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
acfbd3
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
acfbd3
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
acfbd3
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
acfbd3
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
acfbd3
POSSIBILITY OF SUCH DAMAGES.
acfbd3
acfbd3
                     END OF TERMS AND CONDITIONS
acfbd3
acfbd3
            How to Apply These Terms to Your New Programs
acfbd3
acfbd3
  If you develop a new program, and you want it to be of the greatest
acfbd3
possible use to the public, the best way to achieve this is to make it
acfbd3
free software which everyone can redistribute and change under these terms.
acfbd3
acfbd3
  To do so, attach the following notices to the program.  It is safest
acfbd3
to attach them to the start of each source file to most effectively
acfbd3
convey the exclusion of warranty; and each file should have at least
acfbd3
the "copyright" line and a pointer to where the full notice is found.
acfbd3
acfbd3
    <one line to give the program's name and a brief idea of what it does.>
acfbd3
    Copyright (C) <year>  <name of author>
acfbd3
acfbd3
    This program is free software; you can redistribute it and/or modify
acfbd3
    it under the terms of the GNU General Public License as published by
acfbd3
    the Free Software Foundation; either version 2 of the License, or
acfbd3
    (at your option) any later version.
acfbd3
acfbd3
    This program is distributed in the hope that it will be useful,
acfbd3
    but WITHOUT ANY WARRANTY; without even the implied warranty of
acfbd3
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
acfbd3
    GNU General Public License for more details.
acfbd3
acfbd3
    You should have received a copy of the GNU General Public License along
acfbd3
    with this program; if not, write to the Free Software Foundation, Inc.,
acfbd3
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
acfbd3
acfbd3
Also add information on how to contact you by electronic and paper mail.
acfbd3
acfbd3
If the program is interactive, make it output a short notice like this
acfbd3
when it starts in an interactive mode:
acfbd3
acfbd3
    Gnomovision version 69, Copyright (C) year name of author
acfbd3
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
acfbd3
    This is free software, and you are welcome to redistribute it
acfbd3
    under certain conditions; type `show c' for details.
acfbd3
acfbd3
The hypothetical commands `show w' and `show c' should show the appropriate
acfbd3
parts of the General Public License.  Of course, the commands you use may
acfbd3
be called something other than `show w' and `show c'; they could even be
acfbd3
mouse-clicks or menu items--whatever suits your program.
acfbd3
acfbd3
You should also get your employer (if you work as a programmer) or your
acfbd3
school, if any, to sign a "copyright disclaimer" for the program, if
acfbd3
necessary.  Here is a sample; alter the names:
acfbd3
acfbd3
  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
acfbd3

acfbd3
acfbd3
This General Public License does not permit incorporating your program into
acfbd3
proprietary programs.  If your program is a subroutine library, you may
acfbd3
consider it more useful to permit linking proprietary applications with the
acfbd3
library.  If this is what you want to do, use the GNU Lesser General
acfbd3
Public License instead of this License.
