# -i on the command line, means fast options, so when it's on the
# command line (only), lint and check builds are skipped no matter what
# the setting of their individual flags are in NIGHTLY_OPTIONS.
#
# LINTDIRS can be set in the env file, format is a list of:
#
#	/dirname-to-run-lint-on flag
#
#	Where flag is:	y - enable lint noise diff output
#			n - disable lint noise diff output
#
#	For example: LINTDIRS="$SRC/uts n $SRC/stand y $SRC/psm y"
#
# -A flag in NIGHTLY_OPTIONS checks ABI diffs in .so files
# This option requires a couple of scripts.
#
# OPTHOME and TEAMWARE may be set in the environment to override /opt
# and /opt/teamware defaults.

non-DEBUG is the default build type. Build options can be set in the
NIGHTLY_OPTIONS variable in the <env_file> as follows:

	-G	gate keeper default group of options (-au)

	-N	do not run protocmp
	-O	generate OpenSolaris deliverables
	-R	default group of options for building a release (-mp)
	-U	update proto area in the parent
	-V VERS set the build version string to VERS
	-X	copy x86 IHV proto area
	-a	create cpio archives
	-f	find unreferenced files
	-i	do an incremental build (no "make clobber")
	-l	do "make lint" in $LINTDIRS (default: $SRC y)

	-u	update proto_list_$MACH and friends in the parent workspace;
		when used with -f, also build an unrefmaster.out in the parent
	-w	report on differences between previous and current proto areas
	-z	compress cpio archives with gzip
	-W	Do not report warnings (freeware gate ONLY)
	-S	Build a variant of the source product
		E - build exportable source
		D - build domestic source (exportable + crypt)
