[libexec]$ ./negate --help
negate v1859 (nagios-plugins 1.4.11)
Copyright (c) 2002-2007 Nagios Plugin Development Team
	<nagiosplug-devel at lists.sourceforge.net>

Negates the status of a plugin (returns OK for CRITICAL and vice-versa).
Additional switches can be used to control which state becomes what.

...

Notes:
This plugin is a wrapper to take the output of another plugin and  
invert it.
The full path of the plugin must be provided.
If the wrapped plugin returns OK, the wrapper will return CRITICAL.
If the wrapped plugin returns CRITICAL, the wrapper will return OK.
Otherwise, the output state of the wrapped plugin is unchanged.
