Introduction

PowerPanel for Linux is a software which provides command line interface that 
allows for monitoring of your UPS and control to gracefully shut down the 
computer during a power outage. The pwrstatd daemon runs at startup and 
communicates with the UPS while pwrstat is an interface that allows users to get
the status of the UPS and configure the UPS and daemon itself.
