rcs-checkin is a helper script for checking files into RCS. This pro-
gram is distributed with GNU Emacs.
This program converts files with an old Emacs-style version history for
use with the Emacs 19 version control interface VC, which likes to use
RCS as its back end.
For each file to be processed, 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
The first line of each file is used as its description. 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 ver-
sion 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.
In order to make it easier to use rcs-checkin *, files which are
detectably either RCS masters (with names ending in ,v) or Emacs ver-
sion files (with names containing ~) are ignored.
The program accepts no options.
The Emacs version control interface is documented in the GNU Emacs man-
ual, which you can read using Info, either from Emacs or as a
rcs-checkin was originally written by Paul Eggert. It was revised for
use with GNU Emacs VC by Eric S. Raymond.
