This driver handles events on the power, sleep, and lid buttons.
A daemon reads events from input devices or via netlink and
performs user-defined actions such as shutting down the system.
This is necessary for software-controlled poweroff.

To compile this driver as a module, choose M here:
the module will be called button.
