  15 #       cvs2vendor - move revsisions from files in A to files in B
  16 #
  17 # The primary reason for this script is to move deltas from a
  18 # non-vendor branched repository onto a fresh vendor branched one,
  19 # skipping the initial checkin in assumption that it is the same in
  20 # both repositories.  This way you can take a project that was moved
  21 # into CVS without the benefit of the vendor branch and for all
  22 # intents and purposes add the vendor branch underneath the existing
  23 # deltas.
  24 #
  25 # This script is also a decent example of repository maintenance using
  26 # raw RCS commands (if I do say so myself! ;-).
  27 #
  28 # Tags are preserved.
  29 #
  30 # The timestamp of the initial vendor branch revision will be adjusted
  31 # to be the same as the 1.1 revision of each source file.
  32 #
  33 # Extra branches in the source directory will cause breakage.
  34 #
  35 # Intermediate files are created in the current working directory
  36 # where this script is started.
