The license of flashplugin(-prerelease) requires a download?
There was some discussion in the flashplugin-prerelease's comment
section whether or not the PDF license of Flash Player (that is
bigger than the tarball of the plugin itself) would be required to
download along with the package.
There was a suggestion to just use the post_install to link to the
license (which the same guy said was redundant anyway because "We all
know what we're installing, and how proprietary it is").
I could not care less for the license either but it's not that hard to
just cut out the URL from the source=() section.
