The apmd package provides a means of handling various APM events from
userland code. Using apmd.conf, the apmd(8) configuration file, you
can select the APM events to be handled from userland and specify the
commands for a given event, allowing APM behaviour to be configured
flexibly.
Have Fun!

The apmd package provides a means of handling various APM events from
userland code. Using apmd.conf, the apmd(8) configuration file, you
can select the APM events to be handled from userland and specify the
commands for a given event, allowing APM behaviour to be configured
flexibly.
Have Fun!
