nut-snmp 2.4.1-2ubuntu4.1 (amd64 binary) in ubuntu jaunty

 nut is a client/server uninterruptible power supply (UPS) monitoring system
 that permits the sharing of one (or more) UPS between several machines. The
 'server' monitors the UPS and notifies the 'clients' when the UPS is on
 or has a low battery.
 .
 This package contains snmp-ups, the Meta SNMP UPS Driver, which support
 different MIBS (IETF, MGE, APC) for Network UPS Tools. It adds an SNMP
 Manager interface to the core system. You probably don't need it if
 you don't understand what this is all about.
