Debian Ruby packaging suite

 gem2deb is a set of tools to create Debian package from ruby software
 distributed with Rubygems. gem2tgz converts the .gem file to a tar archive,
 then dh-make-ruby creates a Debian source package from that archive. That
 Debian package uses the included Debhelper7 helper, dh_ruby, to generate
 a proper Debian package. Both pure-ruby and native packages are supported.
