Use 'make rmconfig' it wipes out the stored options. Look into the
Makefile for lines specifying options "OPTIONS="
Oh, yeah, the != (which is documented in the make(7) man page, which is
a very good document) means, send the text in that defition to the
shell, and set the variable to whatever the shell returns, like
MYNAME != echo $$USER
(you need the two dollar signs, because you want the dollar sign to get
to the shell, but Make itself will eat the first one, so send two of
them to get one out to the shell.)
You know one great way to learn make? in ports, directory Mk, is a
bunch of make template files, and the one named bsd.port.mk is a
fantastic doument that clearly illustrates just about every good method
that's available in BSD's make. BSD's make is a very, very good one,
too. Greatly different than the GNU make.
