+#
+# How to use:
+#
+# Save your current display configuration and setup with:
+# $ autorandr --save mobile
+#
+# Connect an additional display, configure your setup and save it:
+# $ autorandr --save docked
+#
+# Now autorandr can detect which hardware setup is active:
+# $ autorandr
+# 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.
+#
+# autorandr tries to avoid reloading an identical configuration. To force the
+# (re)configuration, apply --force.
+#
+# 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
+# ~/.autorandr 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.
+#
+#
+# While the script uses xrandr by default, calling it by the name "autodisper"
+# or "auto-disper" forces it to use the "disper" utility, which is useful for
+# controlling nvidia chipsets. The formats for fingerprinting the current setup
+# and saving/loading the current configuration are adjusted accordingly.
