- To prevent a profile from being loaded, place a script called "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
- ~/.config/autorandr (or ~/.autorandr if you have an old installation) as well
- as in any profile directories: The scripts are executed after a mode switch
- has taken place and can notify window managers.
+ autorandr supports a set of per-profile and global hooks. See the documentation
