You can refer to this document in Pod via "L<perlgpl>"
|

DESCRIPTION
|
||||
This is "The GNU General Public License, version 2". It's here so that
|
||||
modules, programs, etc., that want to declare this as their distribution
|
||||
license, can link to it.
|
||||
|
||||
It is also one of the two licenses Perl allows itself to be
|
||||
redistributed and/or modified; for the other one, the Perl Artistic
|
||||
License, see the perlartistic.

GNU GENERAL PUBLIC LICENSE
|

Version 2, June 1991
|
||||

|
||||
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.

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.
|
||||
|
||||
END OF TERMS AND CONDITIONS

Appendix: 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 a brief idea of what it does.>
|
||||
Copyright (C) 19yy <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) 19yy 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:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

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.
