#	Optional environment variables:
#
#	   name		typical use			description
#
#	STUDIOBIN	$STUDIOBIN/cc		installation of the Sun Studio compilers
#	CC		$CC -c x.c		preferred C compiler
#	CCC		$CCC -c x.cc		preferred C++ compiler
#	MAKE		$MAKE {target}		preferred "make" executable
#	DESTDIR		$DESTDIR/usr/ccs	root of installation tree

# Legal arguments are "clean", "all", and "install".  The default
# is "install".
