-# 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
+# THE FOLLOWING LICENCE AGREEMENT IS PRELIMINARY AND INVALID UNTIL ISSUE #7 AT
+# https://github.com/phillipberndt/autorandr/issues/7
+# HAS BEEN RESOLVED!
#
-# Now autorandr can detect which hardware setup is active:
-# $ autorandr
-# mobile
-# docked (detected)

#
-# 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.
