# HOW TO DO IT:
#
# At this writing, the recommended sequence of commands to produce
# an entire release starting in a bare directory is:
#
#	mkdir SCCS_DIRECTORIES
#	mount `pwd`/SCCS_DIRECTORIES
#	ln -s SCCS_DIRECTORIES/SCCS
#	make POPULATED
#	su -c "make makeinstall"
#	make all
#	su -c "make proto"

#########################
#
# STEP 0: RESOURCES
#
# Before going any further, check to ensure that we have the resources
# and environment we need to build the release.
#

# STEP 1: POPULATE
#
# Assume a parallel hierarchy of SCCS files rooted at ./SCCS_DIRECTORIES.
# The POPULATE pass at least creates all the subdirectories and sets up
# the SCCS links. If a file named RELEASE exists in the current directory,
# and contains a string naming an SID-list file found in ./SIDlist,
# then all the source files needed to build that release will be checked out.

# STEP 1.5 UTIL_BOOT
#
# This step makes and installs from source all those odd ball utilities
# which, in the past, have had new features added which a current build
# would depend on. Because the new version was not installed before the
# build started, the build would come to a halt at the point where the
# new feature was needed. It is expected that this list may grow.
#
# Note: there may at some time develop a "chicken/egg" loop if any of
# these utilities themselves are changed such that they need a new or
# changed header file installed before it could correctly build (the
# new header files are installed after this step in STEP number 2).
# If this rare case arises, you will have to manually install the
# header file(s) before this step.
# Another case to consider is that of config. This program depends
# on yacc, lex, and libln. As these programs are pretty stable,
# and, as any changes to them will probably not affect config,
# it probably will not be a problem. Still, they must be considered
# in the worst case.
