+ *
+ *	Lockrun: This program is used to launch a program out with a lockout
+ *	so that only one can run at a time. It's mainly intended for use out
+ *	of cron so that our five-minute running jobs which run long don't get
+ *	walked on. We find this a *lot* with Cacti jobs which just get hung
+ *	up: it's better to miss a polling period than to stack them up and
+ *	slow each other down.
+ *
+ *	So we use a file which is used for locking: this program attempts to
+ *	lock the file, and if the lock exists, we have to either exit with
+ *	an error, or wait for it to release.
+ *
+ *		lockrun --lockfile=FILE -- my command here
+ *
+ * COMMAND LINE
+ * ------------
+ *
+ * --lockfile=F
+ *
+ *	Specify the name of a file which is used for locking. The file is
+ *	created if necessary (with mode 0666), and no I/O of any kind is
+ *	done. The file is never removed.
+ *
+ * --maxtime=N
+ *
+ *	The script being controlled should run for no more than <N> seconds,
+ *	and if it's beyond that time, we should report it to the standard
+ *	error (which probably gets routed to the user via cron's email).
+ *
+ * --wait
+ *
+ *	When a lock is hit, we normally exit with error, but --wait causes
+ *	it to loop until the lock is released.
+ *
+ * --verbose
+ *
+ *	Show a bit more runtime debugging.
+ *
+ * --quiet
+ *
+ *	Don't show "run is locked" error if things are busy; keeps cron from
+ *	overwhelming you with messages if lockrun overlap is not uncommon.
+ *
+ * --
+ *
+ *	Mark the end of the options: the command to run follows.

+ *	of that same argv[X] string, otherwise we have to get the *next*
+ *	argv[X] string. But it's an error if an option-requiring param
+ *	is at the end of the list with no argument to follow.
+ *
+ *	The option name could be of the form "-C" or "--conf", but we
+ *	grab it from the existing argv[] so we can report it well.
+ *
+ * \return character pointer to the argument
