.SH SYNOPSIS
.B mce
[\fIOPTION\fP]...

.SH DESCRIPTION
.B mce
is a daemon that provides mode control functionality.

On startup,
.B mce
will read the initial states of the various radios from the
radio states file and broadcast these states.

Notifiers are registered for various GConf entries,
as well as
\%D\(hyBus message handlers for the method calls that
.B mce
provides, and \%D\(hyBus signal handlers for the signals that
.B mce
listens to.

.B mce
will also listen to key events from the power button.
If the user preses the power button, the action configured in
.I /etc/mce/mce.ini
will be executed.

Among the other functionality handled by

is the logic for the touch screen and keypad lock,
LED patterns and display backlight control.
