 Everyone is permitted to copy and distribute verbatim copies
Packit d53d01
 of this license document, but changing it is not allowed.

Packit d53d01
                            Preamble
Packit d53d01
Packit d53d01
  The licenses for most software are designed to take away your
Packit d53d01
freedom to share and change it.  By contrast, the GNU General Public
Packit d53d01
License is intended to guarantee your freedom to share and change free
Packit d53d01
software--to make sure the software is free for all its users.  This
Packit d53d01
General Public License applies to most of the Free Software
Packit d53d01
Foundation's software and to any other program whose authors commit to
Packit d53d01
using it.  (Some other Free Software Foundation software is covered by
Packit d53d01
the GNU Lesser General Public License instead.)  You can apply it to
Packit d53d01
your programs, too.
Packit d53d01
Packit d53d01
  When we speak of free software, we are referring to freedom, not
Packit d53d01
price.  Our General Public Licenses are designed to make sure that you
Packit d53d01
have the freedom to distribute copies of free software (and charge for
Packit d53d01
this service if you wish), that you receive source code or can get it
Packit d53d01
if you want it, that you can change the software or use pieces of it
Packit d53d01
in new free programs; and that you know you can do these things.
Packit d53d01
Packit d53d01
  To protect your rights, we need to make restrictions that forbid
Packit d53d01
anyone to deny you these rights or to ask you to surrender the rights.
Packit d53d01
These restrictions translate to certain responsibilities for you if you
Packit d53d01
distribute copies of the software, or if you modify it.
Packit d53d01
Packit d53d01
  For example, if you distribute copies of such a program, whether
Packit d53d01
gratis or for a fee, you must give the recipients all the rights that
Packit d53d01
you have.  You must make sure that they, too, receive or can get the
Packit d53d01
source code.  And you must show them these terms so they know their
Packit d53d01
rights.
Packit d53d01
Packit d53d01
  We protect your rights with two steps: (1) copyright the software, and
Packit d53d01
(2) offer you this license which gives you legal permission to copy,
Packit d53d01
distribute and/or modify the software.
Packit d53d01
Packit d53d01
  Also, for each author's protection and ours, we want to make certain
Packit d53d01
that everyone understands that there is no warranty for this free
Packit d53d01
software.  If the software is modified by someone else and passed on, we
Packit d53d01
want its recipients to know that what they have is not the original, so
Packit d53d01
that any problems introduced by others will not reflect on the original
Packit d53d01
authors' reputations.
Packit d53d01
Packit d53d01
  Finally, any free program is threatened constantly by software
Packit d53d01
patents.  We wish to avoid the danger that redistributors of a free
Packit d53d01
program will individually obtain patent licenses, in effect making the
Packit d53d01
program proprietary.  To prevent this, we have made it clear that any
Packit d53d01
patent must be licensed for everyone's free use or not licensed at all.
Packit d53d01
Packit d53d01
  The precise terms and conditions for copying, distribution and
Packit d53d01
modification follow.
Packit d53d01
Packit d53d01
                    GNU GENERAL PUBLIC LICENSE
Packit d53d01
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
Packit d53d01
Packit d53d01
  0. This License applies to any program or other work which contains
Packit d53d01
a notice placed by the copyright holder saying it may be distributed
Packit d53d01
under the terms of this General Public License.  The "Program", below,
Packit d53d01
refers to any such program or work, and a "work based on the Program"
Packit d53d01
means either the Program or any derivative work under copyright law:
Packit d53d01
that is to say, a work containing the Program or a portion of it,
Packit d53d01
either verbatim or with modifications and/or translated into another
Packit d53d01
language.  (Hereinafter, translation is included without limitation in
Packit d53d01
the term "modification".)  Each licensee is addressed as "you".
Packit d53d01
Packit d53d01
Activities other than copying, distribution and modification are not
Packit d53d01
covered by this License; they are outside its scope.  The act of
Packit d53d01
running the Program is not restricted, and the output from the Program
Packit d53d01
is covered only if its contents constitute a work based on the
Packit d53d01
Program (independent of having been made by running the Program).
Packit d53d01
Whether that is true depends on what the Program does.
Packit d53d01
Packit d53d01
  1. You may copy and distribute verbatim copies of the Program's
Packit d53d01
source code as you receive it, in any medium, provided that you
Packit d53d01
conspicuously and appropriately publish on each copy an appropriate
Packit d53d01
copyright notice and disclaimer of warranty; keep intact all the
Packit d53d01
notices that refer to this License and to the absence of any warranty;
Packit d53d01
and give any other recipients of the Program a copy of this License
Packit d53d01
along with the Program.
Packit d53d01
Packit d53d01
You may charge a fee for the physical act of transferring a copy, and
Packit d53d01
you may at your option offer warranty protection in exchange for a fee.
Packit d53d01
Packit d53d01
  2. You may modify your copy or copies of the Program or any portion
Packit d53d01
of it, thus forming a work based on the Program, and copy and
Packit d53d01
distribute such modifications or work under the terms of Section 1
Packit d53d01
above, provided that you also meet all of these conditions:
Packit d53d01
Packit d53d01
    a) You must cause the modified files to carry prominent notices
Packit d53d01
    stating that you changed the files and the date of any change.
Packit d53d01
Packit d53d01
    b) You must cause any work that you distribute or publish, that in
Packit d53d01
    whole or in part contains or is derived from the Program or any
Packit d53d01
    part thereof, to be licensed as a whole at no charge to all third
Packit d53d01
    parties under the terms of this License.
Packit d53d01
Packit d53d01
    c) If the modified program normally reads commands interactively
Packit d53d01
    when run, you must cause it, when started running for such
Packit d53d01
    interactive use in the most ordinary way, to print or display an
Packit d53d01
    announcement including an appropriate copyright notice and a
Packit d53d01
    notice that there is no warranty (or else, saying that you provide
Packit d53d01
    a warranty) and that users may redistribute the program under
Packit d53d01
    these conditions, and telling the user how to view a copy of this
Packit d53d01
    License.  (Exception: if the Program itself is interactive but
Packit d53d01
    does not normally print such an announcement, your work based on
Packit d53d01
    the Program is not required to print an announcement.)
Packit d53d01
Packit d53d01
These requirements apply to the modified work as a whole.  If
Packit d53d01
identifiable sections of that work are not derived from the Program,
Packit d53d01
and can be reasonably considered independent and separate works in
Packit d53d01
themselves, then this License, and its terms, do not apply to those
Packit d53d01
sections when you distribute them as separate works.  But when you
Packit d53d01
distribute the same sections as part of a whole which is a work based
Packit d53d01
on the Program, the distribution of the whole must be on the terms of
Packit d53d01
this License, whose permissions for other licensees extend to the
Packit d53d01
entire whole, and thus to each and every part regardless of who wrote it.
Packit d53d01
Packit d53d01
Thus, it is not the intent of this section to claim rights or contest
Packit d53d01
your rights to work written entirely by you; rather, the intent is to
Packit d53d01
exercise the right to control the distribution of derivative or
Packit d53d01
collective works based on the Program.
Packit d53d01
Packit d53d01
In addition, mere aggregation of another work not based on the Program
Packit d53d01
with the Program (or with a work based on the Program) on a volume of
Packit d53d01
a storage or distribution medium does not bring the other work under
Packit d53d01
the scope of this License.
Packit d53d01
Packit d53d01
  3. You may copy and distribute the Program (or a work based on it,
Packit d53d01
under Section 2) in object code or executable form under the terms of
Packit d53d01
Sections 1 and 2 above provided that you also do one of the following:
Packit d53d01
Packit d53d01
    a) Accompany it with the complete corresponding machine-readable
Packit d53d01
    source code, which must be distributed under the terms of Sections
Packit d53d01
    1 and 2 above on a medium customarily used for software interchange; or,
Packit d53d01
Packit d53d01
    b) Accompany it with a written offer, valid for at least three
Packit d53d01
    years, to give any third party, for a charge no more than your
Packit d53d01
    cost of physically performing source distribution, a complete
Packit d53d01
    machine-readable copy of the corresponding source code, to be
Packit d53d01
    distributed under the terms of Sections 1 and 2 above on a medium
Packit d53d01
    customarily used for software interchange; or,
Packit d53d01
Packit d53d01
    c) Accompany it with the information you received as to the offer
Packit d53d01
    to distribute corresponding source code.  (This alternative is
Packit d53d01
    allowed only for noncommercial distribution and only if you
Packit d53d01
    received the program in object code or executable form with such
Packit d53d01
    an offer, in accord with Subsection b above.)
Packit d53d01
Packit d53d01
The source code for a work means the preferred form of the work for
Packit d53d01
making modifications to it.  For an executable work, complete source
Packit d53d01
code means all the source code for all modules it contains, plus any
Packit d53d01
associated interface definition files, plus the scripts used to
Packit d53d01
control compilation and installation of the executable.  However, as a
Packit d53d01
special exception, the source code distributed need not include
Packit d53d01
anything that is normally distributed (in either source or binary
Packit d53d01
form) with the major components (compiler, kernel, and so on) of the
Packit d53d01
operating system on which the executable runs, unless that component
Packit d53d01
itself accompanies the executable.
Packit d53d01
Packit d53d01
If distribution of executable or object code is made by offering
Packit d53d01
access to copy from a designated place, then offering equivalent
Packit d53d01
access to copy the source code from the same place counts as
Packit d53d01
distribution of the source code, even though third parties are not
Packit d53d01
compelled to copy the source along with the object code.
Packit d53d01
Packit d53d01
  4. You may not copy, modify, sublicense, or distribute the Program
Packit d53d01
except as expressly provided under this License.  Any attempt
Packit d53d01
otherwise to copy, modify, sublicense or distribute the Program is
Packit d53d01
void, and will automatically terminate your rights under this License.
Packit d53d01
However, parties who have received copies, or rights, from you under
Packit d53d01
this License will not have their licenses terminated so long as such
Packit d53d01
parties remain in full compliance.
Packit d53d01
Packit d53d01
  5. You are not required to accept this License, since you have not
Packit d53d01
signed it.  However, nothing else grants you permission to modify or
Packit d53d01
distribute the Program or its derivative works.  These actions are
Packit d53d01
prohibited by law if you do not accept this License.  Therefore, by
Packit d53d01
modifying or distributing the Program (or any work based on the
Packit d53d01
Program), you indicate your acceptance of this License to do so, and
Packit d53d01
all its terms and conditions for copying, distributing or modifying
Packit d53d01
the Program or works based on it.
Packit d53d01
Packit d53d01
  6. Each time you redistribute the Program (or any work based on the
Packit d53d01
Program), the recipient automatically receives a license from the
Packit d53d01
original licensor to copy, distribute or modify the Program subject to
Packit d53d01
these terms and conditions.  You may not impose any further
Packit d53d01
restrictions on the recipients' exercise of the rights granted herein.
Packit d53d01
You are not responsible for enforcing compliance by third parties to
Packit d53d01
this License.
Packit d53d01
Packit d53d01
  7. If, as a consequence of a court judgment or allegation of patent
Packit d53d01
infringement or for any other reason (not limited to patent issues),
Packit d53d01
conditions are imposed on you (whether by court order, agreement or
Packit d53d01
otherwise) that contradict the conditions of this License, they do not
Packit d53d01
excuse you from the conditions of this License.  If you cannot
Packit d53d01
distribute so as to satisfy simultaneously your obligations under this
Packit d53d01
License and any other pertinent obligations, then as a consequence you
Packit d53d01
may not distribute the Program at all.  For example, if a patent
Packit d53d01
license would not permit royalty-free redistribution of the Program by
Packit d53d01
all those who receive copies directly or indirectly through you, then
Packit d53d01
the only way you could satisfy both it and this License would be to
Packit d53d01
refrain entirely from distribution of the Program.
Packit d53d01
Packit d53d01
If any portion of this section is held invalid or unenforceable under
Packit d53d01
any particular circumstance, the balance of the section is intended to
Packit d53d01
apply and the section as a whole is intended to apply in other
Packit d53d01
circumstances.
Packit d53d01
Packit d53d01
It is not the purpose of this section to induce you to infringe any
Packit d53d01
patents or other property right claims or to contest validity of any
Packit d53d01
such claims; this section has the sole purpose of protecting the
Packit d53d01
integrity of the free software distribution system, which is
Packit d53d01
implemented by public license practices.  Many people have made
Packit d53d01
generous contributions to the wide range of software distributed
Packit d53d01
through that system in reliance on consistent application of that
Packit d53d01
system; it is up to the author/donor to decide if he or she is willing
Packit d53d01
to distribute software through any other system and a licensee cannot
Packit d53d01
impose that choice.
Packit d53d01
Packit d53d01
This section is intended to make thoroughly clear what is believed to
Packit d53d01
be a consequence of the rest of this License.
Packit d53d01
Packit d53d01
  8. If the distribution and/or use of the Program is restricted in
Packit d53d01
certain countries either by patents or by copyrighted interfaces, the
Packit d53d01
original copyright holder who places the Program under this License
Packit d53d01
may add an explicit geographical distribution limitation excluding
Packit d53d01
those countries, so that distribution is permitted only in or among
Packit d53d01
countries not thus excluded.  In such case, this License incorporates
Packit d53d01
the limitation as if written in the body of this License.
Packit d53d01
Packit d53d01
  9. The Free Software Foundation may publish revised and/or new versions
Packit d53d01
of the General Public License from time to time.  Such new versions will
Packit d53d01
be similar in spirit to the present version, but may differ in detail to
Packit d53d01
address new problems or concerns.
Packit d53d01
Packit d53d01
Each version is given a distinguishing version number.  If the Program
Packit d53d01
specifies a version number of this License which applies to it and "any
Packit d53d01
later version", you have the option of following the terms and conditions
Packit d53d01
either of that version or of any later version published by the Free
Packit d53d01
Software Foundation.  If the Program does not specify a version number of
Packit d53d01
this License, you may choose any version ever published by the Free Software
Packit d53d01
Foundation.
Packit d53d01
Packit d53d01
  10. If you wish to incorporate parts of the Program into other free
Packit d53d01
programs whose distribution conditions are different, write to the author
Packit d53d01
to ask for permission.  For software which is copyrighted by the Free
Packit d53d01
Software Foundation, write to the Free Software Foundation; we sometimes
Packit d53d01
make exceptions for this.  Our decision will be guided by the two goals
Packit d53d01
of preserving the free status of all derivatives of our free software and
Packit d53d01
of promoting the sharing and reuse of software generally.
Packit d53d01
Packit d53d01
                            NO WARRANTY
Packit d53d01
Packit d53d01
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
Packit d53d01
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
Packit d53d01
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
Packit d53d01
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
Packit d53d01
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
Packit d53d01
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
Packit d53d01
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
Packit d53d01
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
Packit d53d01
REPAIR OR CORRECTION.
Packit d53d01
Packit d53d01
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
Packit d53d01
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
Packit d53d01
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
Packit d53d01
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
Packit d53d01
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
Packit d53d01
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
Packit d53d01
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
Packit d53d01
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
Packit d53d01
POSSIBILITY OF SUCH DAMAGES.
Packit d53d01
Packit d53d01
                     END OF TERMS AND CONDITIONS
Packit d53d01
Packit d53d01
            How to Apply These Terms to Your New Programs
Packit d53d01
Packit d53d01
  If you develop a new program, and you want it to be of the greatest
Packit d53d01
possible use to the public, the best way to achieve this is to make it
Packit d53d01
free software which everyone can redistribute and change under these terms.
Packit d53d01
Packit d53d01
  To do so, attach the following notices to the program.  It is safest
Packit d53d01
to attach them to the start of each source file to most effectively
Packit d53d01
convey the exclusion of warranty; and each file should have at least
Packit d53d01
the "copyright" line and a pointer to where the full notice is found.
Packit d53d01
Packit d53d01
    <one line to give the program's name and a brief idea of what it does.>
Packit d53d01
    Copyright (C) <year>  <name of author>
Packit d53d01
Packit d53d01
    This program is free software; you can redistribute it and/or modify
Packit d53d01
    it under the terms of the GNU General Public License as published by
Packit d53d01
    the Free Software Foundation; either version 2 of the License, or
Packit d53d01
    (at your option) any later version.
Packit d53d01
Packit d53d01
    This program is distributed in the hope that it will be useful,
Packit d53d01
    but WITHOUT ANY WARRANTY; without even the implied warranty of
Packit d53d01
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
Packit d53d01
    GNU General Public License for more details.
Packit d53d01
Packit d53d01
    You should have received a copy of the GNU General Public License along
Packit d53d01
    with this program; if not, write to the Free Software Foundation, Inc.,
Packit d53d01
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Packit d53d01
Packit d53d01
Also add information on how to contact you by electronic and paper mail.
Packit d53d01
Packit d53d01
If the program is interactive, make it output a short notice like this
Packit d53d01
when it starts in an interactive mode:
Packit d53d01
Packit d53d01
    Gnomovision version 69, Copyright (C) year name of author
Packit d53d01
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
Packit d53d01
    This is free software, and you are welcome to redistribute it
Packit d53d01
    under certain conditions; type `show c' for details.
Packit d53d01
Packit d53d01
The hypothetical commands `show w' and `show c' should show the appropriate
Packit d53d01
parts of the General Public License.  Of course, the commands you use may
Packit d53d01
be called something other than `show w' and `show c'; they could even be
Packit d53d01
mouse-clicks or menu items--whatever suits your program.
Packit d53d01
Packit d53d01
You should also get your employer (if you work as a programmer) or your
Packit d53d01
school, if any, to sign a "copyright disclaimer" for the program, if
Packit d53d01
necessary.  Here is a sample; alter the names:
Packit d53d01
Packit d53d01
  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
Packit d53d01

Packit d53d01
This General Public License does not permit incorporating your program into
Packit d53d01
proprietary programs.  If your program is a subroutine library, you may
Packit d53d01
consider it more useful to permit linking proprietary applications with the
Packit d53d01
library.  If this is what you want to do, use the GNU Lesser General
Packit d53d01
Public License instead of this License.
