25 Some specific portions of INN are covered by different licenses. Those
26 licenses, if present, will be noted prominantly at the top of those source
27 files. Specifically (but possibly not comprehensively):
29 authprogs/smbval/*, backends/send-uucp.in, and control/perl-nocem.in
30 are under the GNU General Public License. See doc/GPL for a copy of
33 backends/shrinkfile.c, frontends/scanspool.in, lib/concat.c,
34 lib/hstrerror.c, lib/inet_aton.c, lib/inet_ntoa.c, lib/memcmp.c,
35 lib/parsedate.y, lib/pread.c, lib/pwrite.c, lib/setenv.c, lib/seteuid.c,
36 lib/strerror.c, lib/strlcat.c and lib/strlcpy.c are in the public
39 lib/snprintf.c may be used for any purpose as long as the author's
40 notice remains intact in all source code distributions.
42 control/gpgverify.in, control/pgpverify.in and control/signcontrol.in
43 are under a BSD-style license (with the advertising clause) with UUNET
44 Technologies, Inc. as the copyright holder. See the end of those files
47 control/controlchan.in and control/modules/*.pl are covered by a
48 two-clause BSD-style license (no advertising clause). See the
49 beginning of those files for details.
51 lib/strcasecmp.c, lib/strspn.c, and lib/strtok.c are taken from BSD
52 sources and are covered by the standard BSD license. See those files
55 lib/md5.c is covered under the standard free MD5 license from RSA Data
56 Security. See the file for more details. A clarification is also
57 provided here: <http://www.ietf.org/ietf/IPR/RSA-MD-all>.
59 "Implementations of these message-digest algorithms, including
60 implementations derived from the reference C code in RFC-1319,
61 RFC-1320, and RFC-1321, may be made, used, and sold without
62 license from RSA for any purpose."
64 history/his.c and history/hisv6/hisv6.c are under a license very
65 similar to the new BSD license (no advertising clause) but with Thus
66 plc as the copyright holder. See those files for details.
68 lib/tst.c, include/inn/tst.h and doc/pod/tst.pod are derived from
69 <http://www.octavian.org/cs/tst1.3.tar.gz> and are under the new BSD
70 license (no advertising clause), but with Peter A. Friend as the
73 tests/runtests.c is covered under a license very similar to the MIT/X
74 Consortium license. See the beginning of the file for details.
76 Note that all portions of INN that link with core INN code have to be
77 covered by licenses compatible with the license at the top of this file,
78 and since INN links with several external libraries if so configured (such
79 as OpenSSL), should also be compatible with the licenses of those external
80 libraries to be safe. Some portions of this distribution are covered by
81 more restrictive licenses, but all of that code is completely stand-alone,
82 either as a standalone script or as code that compiles into a separate
85 Please note that the files in the contrib directory are not properly part
86 of INN and may be under widely varying licenses. Please see each file
87 and/or its documentation for license information.
