−# 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.
