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.
