Comment # 10 on bug 957528 from S. B.

Another thing to take into account: There are two situations where the user
needs help to install language packages--

The first would be when configuring additional language(s) for an installed
system, in which all of the corresponding language packs need to be found and
installed for the installed applications.

The other situation would be when the user installs a single additional
application. It would be best to not have to manually run an "update language
packs" tool every time, but rather have the relevant lang packages be
automatically located and installed whenever any additional packages are added.
