cbatticon - 1.6.9-1+b1 main

Utility that displays battery information as battery status, remaining
percentage, remaining time, using an icon in the system tray.
.
Based on code from xbattbar-acpi, cbatticon sits in your system tray,
reporting on battery events, like plug-in, critical, remaining, etc.
.
A regular user can (re)define custom system's behaviour, like performing
graceful shutdown on critical status, by user-defined thresholds and commands
on low power/critical.
