I have a small perl script in my $CVSROOT/CVSROOT directory that goes
like this:

	#!/usr/bin/perl

	# This script is a small tool that can be used to update $CVSROOT/passwd
	# files, by ommiting pairs of username:password (with password being the
	# encrypted form of the second command line argument.
	#
	# $Id: cvspasswd.pl,v 1.1 2000/07/02 23:28:10 charon Exp $

	&usage unless (defined($user = $ARGV[0]));
	&usage unless (defined($pass = $ARGV[1]));

	$salt = join '', ('.', '/', 0..9, 'A'..'Z',
	               'a'..'z')[rand 64, rand 64];
	$crypted = crypt($pass, $salt);
	print "$user:$crypted:cvs\n";

	sub usage {
	    die "usage: cvspasswd USER PASS\n";
	}

With this script, I can write something like:

	% perl cvspasswd.pl username password >> ~cvs/CVSROOT/passwd

and have the password added for a new user in CVSROOT/passwd.  Of
course, if the user already exists in CVSROOT/passwd or you don't want
to give everyone the same rights as user `cvs' while they're using
cvs's :pserver: access method, you might have to edit manually
CVSROOT/passwd after this is done.
