The E-AcpiPower epplet is based on E-Power. It is
modified to read battery status information using
the new acpi kernel module, making it much more
accurate and reliable than the old apm method.

Up to four separate batteries are now detected
automatically and represented as one big virtual
battery. There is no need to enter /proc/acpi path
names anymore, as the relevant directories are now
scanned for the appropriate files.
