wmapm: An APM display program designed for WindowMaker Displays the Advanced Power Management (APM) status of your computer in a small icon. This includes battery or AC operation, battery life remaining (both in percentage and graph), time left until battery-depletion, charging status, and battery status. There's nothing in the program that makes it require WindowMaker, except maybe the look. To use this program you need to enable APM support for your kernel during configuration; the corresponding questions are in the 'Character devices' section. From Debian 3.0r0 APT
