+# apmd_proxy - program dispatcher for APM daemon
+#
+# Written by Craig Markwardt (craigm@lheamail.gsfc.nasa.gov) 21 May 1999
+# Modified for Debian by Avery Pennarun
+#
+# This shell script is called by the APM daemon (apmd) when a power
+# management event occurs. Its first and second arguments describe the
+# event. For example, apmd will call "apmd_proxy suspend system" just
+# before the system is suspended.
+#
+# Here are the possible arguments:
+#
+# start - APM daemon has started
+# stop - APM daemon is shutting down
+# suspend critical - APM system indicates critical suspend (++)
+# suspend system - APM system has requested suspend mode
+# suspend user - User has requested suspend mode
+# standby system - APM system has requested standby mode
+# standby user - User has requested standby mode
+# resume suspend - System has resumed from suspend mode
+# resume standby - System has resumed from standby mode
+# resume critical - System has resumed from critical suspend
+# change battery - APM system reported low battery
+# change power - APM system reported AC/battery change
+# change time - APM system reported time change (*)
+# change capability - APM system reported config. change (+)
+#
+# (*) - APM daemon may be configured to not call these sequences
+# (+) - Available if APM kernel supports it.
+# (++) - "suspend critical" is never passed to apmd from the kernel,
+# so we will never see it here. Scripts that process "resume
+# critical" events need to take this into account.
+#
+# It is the proxy script's responsibility to examine the APM status
+# (via /proc/apm) or other status and to take appropriate actions.
+# For example, the script might unmount network drives before the
+# machine is suspended.
+#
+# In Debian, the usual way of adding functionality to the proxy is to
+# add a script to /etc/apm/event.d. This script will be called by
+# apmd_proxy (via run-parts) with the same arguments.
+#
+# If it is important that a certain set of script be run in a certain
+# order on suspend and in a different order on resume, then put all
+# the scripts in /etc/apm/scripts.d instead of /etc/apm/event.d and
+# symlink to these from /etc/apm/suspend.d, /etc/apm/resume.d and
+# /etc/apm/other.d using names whose lexicographical order is the same
+# as the desired order of execution.
+#
+# If the kernel's APM driver supports it, apmd_proxy can return a non-zero
+# exit status on suspend and standby events, indicating that the suspend
+# or standby event should be rejected.
+#
+# *******************************************************************
+
+set -e
+
+# The following doesn't yet work, because current kernels (up to at least
+# 2.4.20) do not support rejection of APM events. Supporting this would
+# require substantial modifications to the APM driver. We will re-enable
+# this feature if the driver is ever modified. -- cph@debian.org
