	I guess since Mocka is in non-free now, I could include BEG with
it.  But it will be linked against libc5, so I really shouldn't, anyway.
I did not get any more mail from Thilo Gaul on the possibility of
contributing a 'C Version', which I assumed meant source code.

	I looked pretty thoroughly around the net for the last free
version. I got 9209, which claims to be the last free version.  Are you
saying that there is some way to use rex and lalr to produce the
Scanner.tab and Parser.tab files needed to build the tools in cocktail ?
I spent a bit of time trying to discover this, but I couldn't figure it
	Thanks for the help.  I am not a modula user. I was just spending
a few weeks in the summer packaging things. Mocka looks pretty nice btw.
It sure chews up code fast.
	If you want to comment on the packages, They are in slink as
'mocka' and 'm2c'.  Cocktail (and mtc) is not there yet.
