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