The file layout is modelled on the way Sun lays out the files for their
JDK and JRE.  It is decidedly non-FHS/FSSTND, but on the other hand,
it makes it easier to use Kaffe as a drop-in replacement for the JDK.

For packaging for a distro, I'd suggest using --prefix=3D/usr/lib/kaffe,
so you'd have the JDK/JRE stuff packages all together in the same spot,
and use symbolic links in /usr/bin to link the binaries.  That way, you
get the best of both worlds.

Of course, Debian has some more elaborate policies for their Java stuff,
so you'd want to check those.

Again, we're using Sun's layout, which does not map well onto the FHS
heirarchy.

I haven't had time to try ant myself.  Maybe some other people on the
list can help.
