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 dependencices and avoid proposing packages which would trigger too many other, unrelated, packages to be installed.
Like all packages included in tasks, the package included in <language> tasks should be suitably generic for a large number of the users of the language (at least 25%).
