//config:	  acpid listens to ACPI events coming either in textual form from
//config:	  /proc/acpi/event (though it is marked deprecated it is still widely
//config:	  used and _is_ a standard) or in binary form from specified evdevs
//config:	  (just use /dev/input/event*).
//config:
//config:	  It parses the event to retrieve ACTION and a possible PARAMETER.
//config:	  It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
//config:	  (if the resulting path is a directory) or directly as an executable.
