acpid 2.0.33 Daemon for delivering ACPI events to user-space programs

acpid is designed to notify user-space programs of Advanced Configuration and Power Interface (ACPI) events. acpid should be started during the system boot, and will run as a background process. When an ACPI event is received from the kernel, acpid will examine the list of rules specified in /etc/acpi/events and execute the rules that match the event.
