Recursion should be as easy as:

	% cd /proj/foo
	% cat Makefile
	SUBDIR=	alpha \
		beta

	.include <bsd.subdir.mk>
	%

The Makefile files of /proj/foo/alpha and /proj/foo/beta will then be
'called' recursively to build the respective module parts.  Note that
the files:

	/proj/foo/alpha/Makefile
	/proj/foo/beta/Makefile

will pull in any Makefile.inc you put in /proj/foo (yes, that is one
level higher than the Makefiles of the subdirs themselves).  This may
seem counter-intuitive at first, but it makes sense if you consider
the common Makefile.inc include file as "things common to all the
subdirs of /proj/foo".

Examples of this sort can be found in abundance in src/.  Just look at
the Makefile for src/bin/, src/usr.bin/, etc.

I don't use gmake if I can avoid it.  Someone else should chime in
with gmake help, if they want.
