[lug] How do you setup a recursive make?

[Holshouser, David]

is make sending this scripting to the shell or is it handled within make?
is this sh syntax specific?
where do I look for info on for loops?

FYI, using gcc make from Tornado2 on an NT box, so if this is passed through
to the shell, I'm in trouble.
