USAGE='Usage: bldenv [-fdt] [ -S E|D|H ] <env_file> [ command ]

Where:
	-c	Force the use of csh - ignore $SHELL
	-f	Invoke csh with -f
	-d	Setup a DEBUG build (default: non-DEBUG)
	-t	use the tools in $SRC/tools
	-S	Build a variant of the source product
		E - build exportable source
		D - build domestic source (exportable + crypt)
		H - build hybrid source (binaries + deleted source)
