+ 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
