Hi Eric

Thanks looks promising but I'm having problems to use it.

I noticed that babel is not a part of 6.30trans and did an upgrade to the
latest current version 7.4.

Unfortunately it's causing problems (all I did was updating a sym-link to
the new package)

Am I supposed to set additional PATHs?

bye
