#! /bin/sh
#
# cvs2vendor - move revsisions from files in A to files in B
#
# The primary reason for this script is to move deltas from a
# non-vendor branched repository onto a fresh vendor branched one,
# skipping the initial checkin in assumption that it is the same in
# both repositories. This way you can take a project that was moved
# into CVS without the benefit of the vendor branch and for all
# intents and purposes add the vendor branch underneath the existing
# deltas.
#
# This script is also a decent example of repository maintenance using
# raw RCS commands (if I do say so myself! ;-).
#
# Tags are preserved.
#
# The timestamp of the initial vendor branch revision will be adjusted
# to be the same as the 1.1 revision of each source file.
#
# Extra branches in the source directory will cause breakage.
#
# Intermediate files are created in the current working directory
# where this script is started.
#
# Written by Greg A. Woods <woods@planix.com>, based on rcs2sccs
# (retains some of the rlog parsing from it).
#
