.SH DESCRIPTION
This manual page documents briefly the
.B wmacpi-ng
command.
.PP
.B wmacpi-ng
is a program that displays the current battery status in a WindowMaker
dock app, on systems that support Intel's Advanced Configuration and
Power Interface specification (ACPI).
.PP
The program monitors a battery, displaying its current percentage
charge via a bar and a numeric value. It also displays the current
power status for the system, the time remaining (calculated based on
the remaining battery capacity and the current rate of power usage),
and a scrolling message with some hopefully useful information.
.PP
Clicking on the window cycles through the batteries that the ACPI
system knows about.
.PP
.B acpi-ng
queries the battery status from the command line. It prints the power
status, the percentage remaining for each battery found, and the time
remaining if the system is on battery, or the time remaining for each
battery to reach full charge if the batteries are charging.
