I won't hold that against you ;-)  After all, you're just volunteering.

I got a halfway sane patch (it ditched the frontend sources from the
tarball :-{) and Johannes Meixner was bugging me at about the same
time, so ...

The frontend is GPL + exception.  However, same frontend won't work
without libesmod.so which is EAPL and distributed WITHOUT source.
Redistributing EAPL'd binary parts is allowed.  You may even modify
them ;-)  and reverse engineer for debugging purposes and debugging
purposes only (to meet the requirement at the top of section 6. of
the LGPL).

BTW, you want to look at non-free/EAPL.en.txt for the exact
conditions.

You're welcome.
