From 4d4250da00e8f202ebcf4523fa25568d04b116ad Mon Sep 17 00:00:00 2001
From: dg <dg@FreeBSD.org>
Date: Sat, 27 Aug 1994 16:14:39 +0000
Subject: 1) Changed ddb into a option rather than a pseudo-device (use options
 DDB    in your kernel config now). 2) Added ps ddb function from 1.1.5.
 Cleaned it up a bit and moved into its    own file. 3) Added \r handing in
 db_printf. 4) Added missing memory usage stats to statclock(). 5) Added dummy
 function to pseudo_set so it will be emitted if there    are no other pseudo
 declarations.
