identify rc.d scripts are from pkgsrc?

What do you think about having pkgsrc-provided rc.d scripts indicate they 
are from pkgsrc and what package?

Something like at the top:

#!/bin/sh
#
#       From pkgsrc package: exim-4.67
#       $NetBSD: exim.sh,v 1.7 2004/11/26 10:17:40 grant Exp $
#
# PROVIDE: mail
# REQUIRE: LOGIN

Or:

#!/bin/sh
#
#       From pkgsrc package: spamd-20070902
# $NetBSD: pfspamd.sh,v 1.1.1.1 2005/06/28 12:43:57 peter Exp $
#
# PROVIDE: pfspamd
# REQUIRE: DAEMON
#


Any other ideas?

This could be useful for postfix, sendmail, sshd, xdm, and others (if 
someone replaced original).
