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.
