Controls / monitors the status of an APC UPS under Linux.
 Allows your computer or server to run for a specified length of
 time on UPS power, and then executes a controlled shutdown in
 the case of an extended power failure.

Description: Monitor UPS and handle line power failures
 The express aim of the genpower package is to add additional functionally
 and a simpler means of configuring UPS monitoring, in a full featured
 suite that can be configured to work with most UPSs featuring an RS232
 monitoring port.
 .
 Depending on the UPS, cable, and the manner in which the genpower
 package is configured, the genpower package provides the following
 features:
 .
  * Line power sensing
  * Low battery detection
  * Physical cable detection
  * The ability to kill the UPS's inverter
 .
 The Debian package has an extra cable description called "apc-pnp"
 that should support all of the above for the APC Back-UPS Pro, Smart-UPS,
 and Matrix-UPS systems using the included Windows-95 Plug-and-Play cable!
