ix
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.
12. If the distribution and/or use of the Library is restricted in certain countries either by
patents or by copyrighted interfaces, the original copyright holder who places the
Library 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.
13. The Free Software Foundation may publish revised and/or new versions of the
Library 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 Library 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 Library does not specify a license
version number, you may choose any version ever published by the Free Software
Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose
distribution conditions are incompatible with these, 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
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
“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 LIBRARY
IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. 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 LIBRARY 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 LIBRARY (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
LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries
If you develop a new library, and you want it to be of the greatest possible use to the
public, we recommend making it free software that everyone can redistribute and
change. You can do so by permitting redistribution under these terms (or, alternatively,
under the terms of the ordinary General Public License).
To apply these terms, attach the following notices to the library. 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 library’s name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or modify it under the terms of
the GNU Library General Public License as published by the Free Software
Foundation; either version 2 of the License, or (at your option) any later version.
This library 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 Library General Public
License for more details.
You should have received a copy of the GNU Library General Public License along
with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin St,
Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school, if
any, to sign a “copyright disclaimer” for the library, if necessary. Here is a sample; alter
the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the library ‘Frob’ (a library
for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That’s all there is to it!
■ About bison_parser
Conditions for Using Bison
The distribution terms for Bison-generated parsers permit using the parsers in nonfree
programs. Before Bison version 2.2, these extra permissions applied only when Bison
was generating LALR(1) parsers in C. And before Bison version 1.24, Bison-generated
parsers could be used only in programs that were free software.
The other GNU programming tools, such as the GNU C compiler, have never had such
a requirement. They could always be used for nonfree software. The reason Bison was
different was not due to a special policy decision; it resulted from applying the usual
General Public License to all of the Bison source code.
The main output of the Bison utility?the Bison parser implementation file?contains a
verbatim copy of a sizable piece of Bison, which is the code for the parser’s
implementation. (The actions from your grammar are inserted into this implementation
at one point, but most of the rest of the implementation is not changed.) When we
applied the GPL terms to the skeleton code for the parser’s implementation, the effect
was to restrict the use of Bison output to free software.
We didn’t change the terms because of sympathy for people who want to make software
proprietary. Software should be free. But we concluded that limiting Bison’s use to free
software was doing little to encourage people to make other software free. So we
decided to make the practical conditions for using Bison match the practical conditions
for using the other GNU tools.
This exception applies when Bison is generating code for a parser. You can tell whether
the exception applies to a Bison output file by inspecting the file for text beginning with
“As a special exception...”. The text spells out the exact terms of the exception.
