   3 #       cvs2vendor - move revsisions from files in A to files in B
   4 #
   5 # The primary reason for this script is to move deltas from a
   6 # non-vendor branched repository onto a fresh vendor branched one,
   7 # skipping the initial checkin in assumption that it is the same in
   8 # both repositories.  This way you can take a project that was moved
   9 # into CVS without the benefit of the vendor branch and for all
  10 # intents and purposes add the vendor branch underneath the existing
  11 # deltas.
  12 #
  13 # This script is also a decent example of repository maintenance using
  14 # raw RCS commands (if I do say so myself! ;-).
  15 #
  16 # Tags are preserved.
  17 #
  18 # The timestamp of the initial vendor branch revision will be adjusted
  19 # to be the same as the 1.1 revision of each source file.
  20 #
  21 # Extra branches in the source directory will cause breakage.
  22 #
  23 # Intermediate files are created in the current working directory
  24 # where this script is started.
