  25 # Arguments which are detectably either RCS masters (with names ending in ,v)
  26 # or Emacs version files  (with names of the form foo.~<number>~) are ignored.
  27 # For each file foo, the script looks for Emacs version files related to it.
  28 # These files are checked in as deltas, oldest first, so that the contents of
  29 # the file itself becomes the latest revision in the master.
  30 #
  31 # The first line of each file is used as its description text.  The file itself
  32 # is not deleted, as under VC with vc-keep-workfiles at its default of t, but
  33 # all the version files are.
  34 #
  35 # If an argument file is already version-controlled under RCS, any version
  36 # files are added to the list of deltas and deleted, and then the workfile
  37 # is checked in again as the latest version.  This is probably not quite
  38 # what was wanted, and is the main reason VC doesn't simply call this to
  39 # do checkins.
  40 #
  41 # This script is intended to be used to convert files with an old-Emacs-style
  42 # version history for use with VC (the Emacs 19 version-control interface),
  43 # which likes to use RCS as its back end.  It was written by Paul Eggert
  44 # and revised/documented for use with VC by Eric S. Raymond, Mar 19 1993.
