---help---
A user-space daemon, acpi, typically read /proc/acpi/event
and handled all ACPI sub-system generated events.
These events are now delivered to user-space via
either the input layer, or as netlink events.
This build option enables the old code for for legacy
user-space implementation. After some time, this will
be moved under CONFIG_ACPI_PROCFS, and then deleted.
