/**
 * \brief This is the main file of the rsyslogd daemon.
 *
 * Please visit the rsyslog project at
 *
 * http://www.rsyslog.com
 *
 * to learn more about it and discuss any questions you may have.
 *
 * rsyslog had initially been forked from the sysklogd project.
 * I would like to express my thanks to the developers of the sysklogd
 * package - without it, I would have had a much harder start...
 *
 * Please note that while rsyslog started from the sysklogd code base,
 * it nowadays has almost nothing left in common with it. Allmost all
 * parts of the code have been rewritten.
 *
 * This Project was intiated and is maintained by
 * Rainer Gerhards <rgerhards@hq.adiscon.com>.
 *
 * For further information, please see http://www.rsyslog.com
 *
 * \author Rainer Gerhards <rgerhards@adiscon.com>
 * \date 2003-10-17
 *       Some initial modifications on the sysklogd package to support
 *       liblogging. These have actually not yet been merged to the
 *       source you see currently (but they hopefully will)
 *
 * \date 2004-10-28
 *       Restarted the modifications of sysklogd. This time, we
 *       focus on a simpler approach first. The initial goal is to
 *       provide MySQL database support (so that syslogd can log
 *       to the database).
 *

	 * the parameters down below in the correct order. For example, we must know the
	 * value of -M before we can do the init, but at the same time we need to have
	 * the base classes init before we can process most of the options. Now, with the
	 * split of functionality, this is no longer a problem. Thanks to varmofekoj for
	 * suggesting this algo.
	 * Note: where we just need to set some flags and can do so without knowledge
	 * of other options, we do this during the inital option processing. With later
	 * versions (if a dependency on -c option is introduced), we must move that code
	 * to other places, but I think it is quite appropriate and saves code to do this
	 * only when actually neeeded.
