Parse::Distname is yet another distribution name parser. It works almost
the same as the CPAN::DistnameInfo manpage, but Parse::Distname takes a
different approach. It tries to extract a version part of a distribution
and treat the rest as a distribution name, contrary to CPAN::DistnameInfo
which tries to define a name part and treat the rest as a version.

Because of this difference, when Parse::Distname parses a weird
distribution name such as "AUTHOR/v1.0.tar.gz", it says the name is empty
and the version is "v1.0", while CPAN::DistnameInfo says the name is "v"
and the version is "1.0". See test files in this distribution if you need
more details. As of this writing, Parse::Distname returns a different
result for about 200+ distributions among about 320000 BackPan
distributions.
