While packaging Snowball-Swedish for Fedora, it was discovered that the license is unclear. According to META.yml and pod in Se.pm, the license is "the same as perl" (i.e. Artistic, or GPL version 1 or later). But you also have a header in Se.pm stating that the program may be distributed under "GPL version 2, *NOT* earlier versions". Can you clarify whether you really mean "same as perl", or "Artistic, or GPL version 2 only", or "Artistic, or GPL version 2 or later", or some other variation. Please also be aware that the same confusion exists for Snowball-Norwegian - I didn't create a separate ticket, but the same question applies.
