.IP
The initial tabs indicate the menu hierarchy:
items indented with a tab is shown in a submenu of the preceding item not indented.
An item without initial tabs is a top-level item.
.IP
+The image is a string of the form "IMG:/path/to/image.png".
+It specifies a image to be shown as icon at the left of the entry.

The label is the string that will be shown as a item in the menu.
An item without label is considered a separator and is drawn as a thin line in the menu
separating the item above from the item below.
