A rewrite of the original Debian's start-stop-daemon Perl script
in C (faster - it is executed many times during system startup).
Written by Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl>,
public domain. Based conceptually on start-stop-daemon.pl, by Ian
Jackson <ijackson@gnu.ai.mit.edu>. May be used and distributed
freely for any purpose. Changes by Christian Schwarz
<schwarz@monet.m.isar.de>, to make output conform to the Debian
Console Message Standard, also placed in public domain. Minor
changes by Klee Dienes <klee@debian.org>, also placed in the Public
Domain.
Changes by Ben Collins <bcollins@debian.org>, added --chuid, --background
and --make-pidfile options, placed in public domain aswell.
Port to OpenBSD by Sontri Tomo Huynh <huynh.29@osu.edu>
and Andreas Schuldei <andreas@schuldei.org>
Changes by Ian Jackson: added --retry (and associated rearrangements).
Modified for Gentoo rc-scripts by Donny Davies <woodchip@gentoo.org>:
I removed the BSD/Hurd/OtherOS stuff, added #include <stddef.h>
and stuck in a #define VERSION "1.9.18". Now it compiles without
the whole automake/config.h dance.
