- * First Written: 04/17/99

- * Modifications:
- * 
- * 05/18/1999 - Modified to work getloadavg where available, and use uptime
- *		where neither proc or getloadavg are found.  Also use autoconf.
- *                 mods by Karl DeBisschop (kdebiss@alum.mit.edu)
- * 07/01/1999 - Added some #DEFINEs to allow compilation under NetBSD, as
- *		suggested by Andy Doran.
- *	           mods by Ethan Galstad (nagios@nagios.org)
- * 07/17/1999 - Initialized la[] array to prevent NetBSD from complaining
- *		   mods by Ethan Galstad (nagios@nagios.org)
- * 08/18/1999 - Integrated some code with common plugin utilities
- *		   mods by Ethan Galstad (nagios@nagios.org)
- * $Date$
- * Note: The load format is the same used by "uptime" and "w"
