The ebuild currently has LICENSE="as-is" which most likely is wrong. - No license is included in the package's tarball. - I cannot find any license information on the HOMEPAGE. Can you please ask upstream for clarification under with terms this package can be distributed?
6 months ping.
Any news here? SRC_URI is still live, so we could go for "all-rights-reserved" plus mirror restriction. The README file says "Borrowed code falls under copyright of the original author", therefore I don't expect that we could get anything better than all-rights-reserved.
Fixed, as discussed in IRC.
