This plugin add support for automatic installation of langpacks.
It is based on a proof of concept originally posted by
Bill Nottingham.

Example:
A Japanese user installs Fedora Live and then wants to install
open-office.org afterwards.  With this plugin installed and
if using Japanese desktop environment,
openoffice.org-langpack-ja_JP will get installed automatically
at the same time.

TODO:
extensibility with metadata for langpacks

FUTURE:
Maybe some fonts and input methods too.
