NAME
dh-make-ruby - build Debian source package from Ruby library USAGE
dh-make-ruby [OPTIONS] TARBALL|DIRECTORY DESCRIPTION
dh-make-ruby will create a basic Debian source package from a tarball named TARBALL generated with gem2tgz, or from a DIRECTORY containing Ruby code and metadata in a .gemspec file. OPTIONS
-p PACKAGE, --package PACKAGE Uses PACKAGE as package name. By default, new packages will be named as ruby-$gem, where $gem is the upstream name. If the package is mainly used as a library, then it should use the default. On the other hand, if the packages is mainly used as an application, then you should drop the ruby- prefix by using this option an explicit package u. --ruby-versions VERSIONS Ruby versions to build the package for. This is used to generate the X-Ruby-Versions: field in the source package, that can later be used to tune this value. By default, gem2deb generates a package that works on all known Ruby versions, but it might be necessary to only build the package for Ruby 1.8, for example (using --ruby-versions "ruby1.8"). -h, --help Displays the help -v, --version Displays version information and exits.
