- 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.

- Another script called "postswitch" can be placed in the directory

- as in any profile directories: The scripts are executed after a mode switch
