That's a good idea!  I think we could have both, like Debian also has a
'tesseract-ocr-all' package for all the languages/scripts.  Which means
the individual variants could be added in at a later time by those
interested, eh :-).

A procedure returning a language-specific package variant would make
sense for that.

Thanks,
