I'd argue here. I think GZIP is better. It is probably more difficult to
use than PKZIP, but if you know what you're doing you'll get much better
results than with PKZIP. I think we again bump against the "user
friendliness" here.

Remember that we're talking about DOS all the time. 90% of people using
DJGPP, have only DOS/Windows on their computers, and in DOS tar is not
at all popular nor standard. Anyone who haven't had any contact with
Unix systems, doesn't even know the name 'tar'. As to price. I don't
know how much it costs, because I use Info-Zip's ZIP which is also free.

Sorry, I don't want to seem hoity-toity here, but I've never read PKZIP
(nor ARJ, RAR or whatever) manual. I think it's enough to type
'something -?|-H' and read what switches does it take. Besides PKZIP has
been on the market for such a long time that it's syntax is probably as
obvious as that of 'cd' command.
