a central command/control point and acts as the SNMP agent for

<p>On startup, (or configuration change) the configuration dictionary
from Control.plist (plus any included files) is written to
/tmp/Control.cnf to provide a record of the latest config.
</p>

that the process is still running correctly. If the user default
string ControlVersion is defined, it is written to one line of
this file and in any case a timestamp is written.
