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.

The purpose of the collection is to make it as simple as possible for
developers to create plugins that conform the Nagios Plugin guidelines
(http://nagiosplug.sourceforge.net/developer-guidelines.html).
