Binary package “gem2deb” in ubuntu mantic
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 Debhelper helper, dh_ruby, to generate
a proper Debian package. Both pure-ruby and native packages are supported.
