Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
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 Library 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.
|
|
|
|
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.
|
|
|
|
END OF TERMS AND CONDITIONS
|
|
|
|
How to Apply These Terms to Your New Programs
|
|
|
|
If you develop a new program, and you want it to be of the greatest
|
|
possible use to the public, the best way to achieve this is to make it free
|
|
software which everyone can redistribute and change under these terms.
|
|
|
|
To do so, attach the following notices to the program. It is safest to
|
|
attach them to the start of each source file to most effectively convey the
|
|
exclusion of warranty; and each file should have at least the "copyright"
|
|
line and a pointer to where the full notice is found.
|
|
|
|
one line to give the program's name and an idea of what it does.
|
|
Copyright (C) yyyy name of author
|
|
|
|
This program is free software; you can redistribute it and/or modify it
|
|
under the terms of the GNU General Public License as published by the Free
|
|
Software Foundation; either version 2 of the License, or (at your option)
|
|
any later version.
|
|
|
|
This program is distributed in the hope that it will be useful, but WITHOUT
|
|
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
|
|
FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for
|
|
more details.
|
|
|
|
You should have received a copy of the GNU General Public License along with
|
|
this program; if not, write to the Free Software Foundation, Inc., 59
|
|
Temple Place - Suite 330, Boston, MA 02111-1307, USA.
|
|
|
|
Also add information on how to contact you by electronic and paper mail.
|
|
|
|
If the program is interactive, make it output a short notice like this when
|
|
it starts in an interactive mode:
|
|
|
|
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
|
|
with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free
|
|
software, and you are welcome to redistribute it under certain conditions;
|
|
type 'show c' for details.
|
|
|
|
The hypothetical commands 'show w' and 'show c' should show the appropriate
|
|
parts of the General Public License. Of course, the commands you use may be
|
|
called something other than 'show w' and 'show c'; they could even be
|
|
mouse-clicks or menu items--whatever suits your program.
|
|
|
|
You should also get your employer (if you work as a programmer) or your
|
|
school, if any, to sign a "copyright disclaimer" for the program, if
|
|
necessary. Here is a sample; alter the names:
|
|
|
|

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