 =head1 DESCRIPTION
 
-Nagios::Plugin and its associated Nagios::Plugin::* modules are a family of perl modules
-to streamline writing Nagios plugins. The main end user modules are Nagios::Plugin, 
-providing an object-oriented interface to the entire Nagios::Plugin::* collection, and 
-Nagios::Plugin::Functions, providing a simpler functional interface to a useful subset of 
-the available functionality.
