family of perl modules to streamline writing Nagios

 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).
