- /* This utility was added to the Kannel source tree for the benefit of
- * those distributions that aren't Debian. It is used by kannel-init.d
- * to start and stop the run_kannel_box daemon.
- * It was copied from the dpkg 1.6.11 source tree on 21 March 2000.
- * If that was very long ago, refreshing the copy would be a good idea,
- * in case bugs were fixed.
- * Richard Braakman

- /*
- * 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.
