# Usage:
# xorg-hotplug.sh [device]
#
#   device  - Name of an Xorg device to configure.
#
# xorg-hotplug should be added to your window manager's list of startup programs. If
# run with no arguments, it will sit in the background monitoring for hotplug events
# by monitoring the Xorg log file. When a new device is connected, it will automatically
# launch a new instance of itself with the name of the deivce to handle configuration.
#
# The bottom half of this script should be customized to change the list of devices that
# it recognizes and the commands that get run in response.

# If run without arguments, monitor for xorg hotplug events
