A stand-alone (non-toolkit based) menu package for X11
Description:
The style comes from the menus provided on the Xerox Dandelion running Interlisp. Normally, the menu appears as a single pane of choices. However, selected items in the menu have an arrow off to one side of the choice. If the user moves the pointer into this area, a sub-menu appears to one side of the initial menu pane.
