In the original message from May Timo asked about hfst and hfst-ospell and
that's why I wanted to check them both.
Yes, we could just package hfst-ospell but the ultimate goal for this whole
exercise is to improve the language support in Debian and that cannot be done
without packaging the dictionaries as well. And you can't have a dictionary in
the main Debian distributions unless it can be built using tools that are in
Debian. For this we will need to package the hfst tools.

This sounds good.

The current situation would make ZHFST binaries unredistributable in Debian
main and other places that have a policy of requiring the use of free
compilers. Legally they might be redistributable (I guess).

Yes, there is no problem at all with distributing hfst-enabled libvoikko.

I have no idea about this one.
