125/* EXAMPLES TO END OF FILE
126
127# Examples of notify hooks.  A notify is a generic way for a kernel
128# subsystem to send event notification to userland.
129
130# Here are some examples of ACPI notify handlers.  ACPI subsystems that
131# generate notifies include the AC adapter, power/sleep buttons,
132# control method batteries, lid switch, and thermal zones.
133#
134# Information returned is not always the same as the ACPI notify
135# events.  See the ACPI specification for more information about
136# notifies.  Here is the information returned for each subsystem:
137#
138# ACAD:            AC line state (0 is offline, 1 is online)
139# Button:          Button pressed (0 for power, 1 for sleep)
140# CMBAT:           ACPI battery events
141# Lid:             Lid state (0 is closed, 1 is open)
142# Suspend, Resume: Suspend and resume notification
143# Thermal:         ACPI thermal zone events
144#
145# This example calls a script when the AC state changes, passing the
146# notify value as the first argument.  If the state is 0x00, it might
147# call some sysctls to implement economy mode.  If 0x01, it might set
148# the mode to performance.
