Debian uses "or" plus "and" keywords: License: GPL-2+ or Artistic-2.0 License: GPL-2+ and BSD Also, comma is used to change the priority of "or/and": License: GPL-2+ or Artistic-2.0, and BSD Licenses with spaces are allowed: License: GPL-2+ with OpenSSL exception And, BTW, "GPL version 2 or later" is specified as "GPL-2+". The format is detailed here: http://dep.debian.net/deps/dep5/ I guess, we can try to adopt the "and/or" syntax... -- Denys _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
