Probably would be the better solution, and also just skip tests for which
the languages are not installed.

This might be actually be an advantage - if changes are detected, the
exported file can be evaluated visually and added to the "aceptable
results", either generally or for a user.

Point taken - I haven't considered that.

Exactly.

Yes - I have a few times run into problems due to my configuration file and
only realized it later - if there would be ab org file which I could use to
test easily my configuration directly after making the changes, life would
have been much easier for me. This would also be useful for questions on the
mailing list and for a kind of "quality control" for published configs on
the web.
