ruby-gettext binary package in Ubuntu Xenial amd64

 This Ruby package is a localization library and toolset modeled after
 GNU gettext, and with a similar simple API.

 It provides:
  * rxgettext - creates gettext-compatible PO files from Ruby scripts;
  * rmsginit - create a new PO file with user's environment and input;
  * rmsgfmt - creates a MO file from a PO file;
  * rmsgmerge - extracts translatable strings from Ruby scripts.
