Each menu entry is described by a subdirectory. Each subdirectory
can contain the following files which further describe the entry:
title A file containing the title of the entry as shown in the menu
box If present, the entry is a ‘bool’ entry. The file contains a
name from which the current state of the bool is taken from and saved
to.
action if present this file contains a shell script which is executed when
when the entry is selected.
If neither ‘box’ or ‘action’ are present, this entry is considered a submenu
containing more entries.
