% Author: Guido Gonzato, <ggonza@tin.it>. Contributions by JED.
%
% Version: 1.0.1. This file provides an interface to RCS a la
% Emacs (sort of).
%
% Installation: unless rcs.sl is already loaded from site.sl (check),
% insert this line in your .jedrc:
%
% () = evalfile ("rcs.sl");
%
% or, better, insert autoload lines in your defaults.sl
% like this:
%
% autoload ("rcs_open_file", "rcs.sl");
% autoload ("rcs_check_in_and_out", "rcs.sl");
% autoload ("rcs_read_log", "rcs.sl");
%
% Usage: rcs_open_file () -- open an RCS file
% rcs_check_in_and_out () -- check in/out an RCS file
% rcs_read_log () -- read the change history
%
% you might want to set these key bindings in your .jedrc:
%
% setkey_reserved ("rcs_open_file", "vf");
% setkey_reserved ("rcs_check_in_and_out", "vv");
% setkey_reserved ("rcs_read_log", "vl");
