   *
   * This is an example of a very basic module.  It does nothing useful other
!  * than printing a message when it is initialized (loaded) and closed
!  * (unloaded).  I would not call that useful...

   * Description:
   *
   * This is an example of a very basic module.  It does nothing useful other
!  * than logging some messages to the main Nagios log file when it is initialized
!  * (loaded), when it is closed (unloaded), and when aggregated status updates
!  * occur.  I would not call that too useful, but hopefully it will serve as a
!  * very basic example of how to write a NEB module...
