+# 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.
