OVERVIEW
--------

There are several components you'll need to get working to
have a fully functional mon installation.

    1. mon, the server
    2. Mon::Client, the Perl library used by some clients
    3. C programs in mon.d
    4. Optional (but highly useful) monitors
    5. A customized mon.cf to make the server do what you want
