The LICENSE file in the tarball is the Artistic license, as listed at http://opensource.org/licenses/Artistic-1.0, with one difference (wdiff output): * "Copyright Holder" is [-whoever is named in the copyright or copyrights for the package.-] {+Christopher B. Powell, <chris@grubbybaby.com>.+} I think that this is negligible, so the package can be labelled with LICENSE="Artistic".
