Appendix D Copying

The majority of the files in the C-INTERCAL distribution are licensed under the GNU General Public License (version 2 or later), but with some exceptions. The files ick-wrap.c and pickwrap.c are licensed under a license that allows them to be used for any purpose and redistributed at will, and are explicitly not GPL’d. This means that C source code generated by the compiler has the same copyright conditions as the original INTERCAL source. (Note that the libraries libick.a and libickmt.a are GPL, though, so you cannot redistribute an executable produced by ick or by linking a C file to either of those libraries unless the original INTERCAL source was GPL.) For similar reasons, the expansion libraries syslibc.c and compunex.c are explicitly public domain. Also, this manual, and the files that are the source code for creating it, are licensed under the GNU Free Documentation License rather than the GPL, and the licenses themselves (fdl-1-2.txi and COPYING.txt) are licensed under a license that allows verbatim redistribution but not creation of derivative works. All other files, though (including the man pages, which are not part of this manual), are licensed under the GPL. For the full text of the GPL, see the file COPYING.txt in the distribution.
