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.
