# Build the "original" msrc (w/o RCS dirs) from the packages.
# WARNING: this script is destructive to the local directory "msrc"!!
# WARNING: NEVER run this script from anyplace but /tmp/, copy the
# resulting "msrc" directory where you want it with cp -ri or rsync.
#
# This has 2 hacks in it: one for "entombing" which should have a package
# name with _base in it, and one to avoid "untmp" being in 2 places (both
# entomb_base and its own package).
