A Mercurial repository, licenses: cc by-sa and GPLv3+ (my rule is: must be compatible to AGPLv3 – v3 or later isn’t possible, because the compatibility of cc by-sa for "or later" is contingent on creativecommons as steward accepting the later version).

EDIT: but I allow GPLv3 *or later* for my parts.
