Dash support in puppet modules version

According to puppet labs (http://docs.puppetlabs.com/puppet/2.7/reference/modules_publishing.html#write-a-modulefile ), puppet modules are using semantic version ( http://semver.org/spec/v1.0.0.html ). This specification allows modules to use dash in version number (i.e. 1.0.1-build22). When one tries to upload module with such version number to pulp repository (pulp-admin puppet repo uploads upload --repo-id puppet -f /root/author-mod-8.1.0-SNAPSHOT.tar.gz ), error is occured:

ValueError: too many values to unpack

That's because dash is used as separator to find author, name and version from filename without above in mind.
