# This script can be used to build the ON component of the source product.
# It should _not_ be used by developers, since it does not work with
# workspaces, or do many of the features that 'nightly' uses to help you
# (like detection errors and warnings, and send mail on completion).
# 'nightly' (and other tools we use) lives in usr/src/tools.
#
# examine arguments. Source customers probably use no arguments, which just
# builds in usr/src from the current directory. They might want to use
# the -B flag, but the others are for use internally for testing the
# compressed cpio archives we deliver to the folks who build the source product.
#

#
# The CDPATH variable causes ksh's `cd' builtin to emit messages to stdout
# under certain circumstances, which can really screw things up; unset it.
