(These symlinks are based on dictionaries.xcu meta data.) You see that this
will introduce dependencies between subpackages. E. g. ar_DZ will depend on ar
subpackage. Hmm.

I am also not sure how to work out obsoletes/provides e. g. for the former en
supackage. You see that, for ar package it is easy, myspell-ar will contain
ar.dic. For english, though, there is nothing like en.dic.
