From: rwatson <rwatson@FreeBSD.org>
Date: Sun, 4 Jun 2000 22:17:11 +0000
Subject: o Introduce libposix1e capability support routines, which provide a  
 standardized interface to the capability support in TrustedBSD. o Not
 currently enabled in Makefile, as this code depends on syscalls   and include
 files that will be committed at a later date.
