This task should install packages which are useful for the users of <language> in a very basic (text-only) environment.
Appropriate choices for such task are:
Documentation in <language>;
Documentation about using Linux or Debian GNU/Linux in <language>;
Dictionaries or word lists for <language>;
Set of manual pages translated in <language>;
Console input methods for <language>;
Console fonts for <language>;
.../...
Translators (or other users) proposing packages to be included in these <language> tasks should be careful about dependencies and avoid proposing packages which would trigger too many other unrelated packages to be installed.
Like all packages included in tasks, packages included in <language> tasks should be suitably generic for a large number of the users of the language (at least 25%).
