# Please place this file /etc/hotplug
#
# input-specific hotplug policy agent.
#
# Kernel Input params are:
#
# ACTION=add
# PHYS=pysical location of device
# NAME=Name of the device
#
# HISTORY:
# 15-Sep-2003 modified to use single configuration file
# /etc/sysconfig/ruby.conf by me :-)
# (Svetoslav Slavtchev)
# added handling for multimedia keys
# but doesn't work as expected :(
# 15-JUN-2003 removed paste
# 07-MAY-2003 remake by Aivils Stoss
# /proc manipulation added
# parse kbd.conf event.conf mouse.conf.
# create necessary symbolic links
# 28-SEP-2002 Initial version from Andreas Schuldei
# andreas (at) schuldei.org
#
