# Build GNU emacs for the Solaris SFW consolidation:

#

# where:

#

#	class - Class of emacs to build (32 or 64)

#	variant - Toolkit variant. One of (lucid, nox, or gtk)

#	insroot - Root of tree where emacs is expected to be

#		be run from. Normally '', signifying the system

#		root, but can be set elsewhere for debugging purposes.

#

# This script assumes that it will be run from usr/src/cmd/emacs,

# from Makefile.sfw, within the environment exported by bldenv.

#

# We use this script rather than doing it all from Makefile.sfw,

# because the series of steps involved in a build is rather complex,

# and it occurs in the Makefile multiple times.
