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