From Mathieu de Naurois:

Changes in the TRootContextMenu that allow creation of multilevel cascaded
menus by using the following syntax:
// *MENU={Hierarchy="Level0/Level1/Level2/Name"}*
// *SUBMENU={Hierarchy="Level0/Level1/Level2/Name"}*
// *TOGGLE={Hierarchy="Level0/Level1/Level2/Name"}*
This improvement allows to reduce the long context menus by grouping related
menu items in a sub-menu and have fully customizable appearance.
