  38 +USE:
  39 +
  40 +To use this module, all  that is needed is to include it in the System
  41 +block of a scan configuration, e.g.:
  42 +
  43 +    <System>
  44 +    ...
  45 +    Include mod_uptime
  46 +    ...
  47 +    </System>
  48 +
  49 +
  50 +PARAMETERS:
  51 +
  52 +There are no parameters for this module.
  53 +
  54 +PLATFORMS:
