Thanks for doing the packaging.  However, watt-32 is something
that most developers need to configure for their needs and then
build for themselves.  The default configuration is too _heavy_
for most purposes.

As a side note:  fragment reassembly is (still) broken in watt-32,
hich is why my dos port of hexenworld doesn't work...
