Adding this SHA256 code made me read the BSD license once again. It says:
* 2. Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. Then there are a few files from Cyrus as well which contain: * 4. Redistributions of any form whatsoever must retain the following * acknowledgment: * "This product includes software developed by Computing Services * at Carnegie Mellon University (http://www.cmu.edu/computing/)." And something similar in utc-mktime.c for Berkeley university as well. I think I'd really like to get rid of those base64.c and utc-mktime.c exceptions.. There's probably also an easier/faster way to implement utc_mktime(). Currently these copyrights or acknowledgments aren't listed anywhere else than in the source files. I don't know if binary packagers have added those, but somehow I doubt it. So I think I should add these to COPYING file somehow. Any suggestions? I'm not the packager of dovecot for pkgsrc (NetBSD and others), but I do package other things. From my viewpoint, 3-clause BSD license is really no problem provided you have an installable and preferably installed file. 4-clause BSD is a bit annoying but not that big a deal. But I don't think it's compatible with LGPL. If you're still the only copyright holder, you can of course make an exception that advertising clause is ok. What I would suggest is that you add a file doc/COPYRIGHT that has whatever is necessary to satisfy all these things. Then, have make install put it in $(prefix)/share/doc/dovecot/COPYRIGHT In pkgsrc right now, there are manual install rules: post-install: ${INSTALL_DATA} ${WRKDIR}/dovecot-example.conf ${DESTDIR}${EGDIR} ${INSTALL_DATA} ${WRKSRC}/doc/dovecot-* ${DESTDIR}${EGDIR} ${INSTALL_SCRIPT} ${WRKDIR}/mkcert.sh ${DESTDIR}${EGDIR} so adding a INSTALL_DATA for COPYRIGHT won't hurt at all. I realize the doc dir is not necessarily the same; it would be nice to have a --with-docdir to set it for the preference of various packaging systems, but not a big deal. Greg
