+#!/bin/sh
+#
+# Automatically select a display configuration based on connected devives
+#
+# Stefan Tomanek <stefan.tomanek@wertarbyte.de>
+#
+# requires disper, the command line display switcher:
+# http://willem.engen.nl/projects/disper/
+#
+#
+# How to use:
+#
+# Save your current display configuration and setup with
+# auto-disper --save mobil
+#
+# Connect an additional display, configure your setup and save it
+# auto-disper --save docked
+#
+# Now auto-disper can detect which hardware setup is active: # auto-disper
+# mobile
+# docked (detected)
+#
+# To automatically reload your setup, just append --change to the command line
+#
+# To manually load a profile, you can use the --load <profile> option.
+#
+# To prevent a profile from being loaded, place a script call "block" in its
+# directory. The script is evaluated before the screen setup is inspected, and
+# in case of it returning a value of 0 the profile is skipped. This can be used
+# to query the status of a docking station you are about to leave.
+#
+# If no suitable profile can be identified, the current configuration is kept.
+# To change this behaviour and switch to a fallback configuration, specify
+# --default <profile>
+#
+# Another script called "postswitch "can be placed in the directory
+# ~/.auto-disper as well as in all profile directories: The scripts are
+# executed after a mode switch has taken place and can notify window managers
+# or other applications about it.
