00002 * vmenu.h
00003 *
00004 * This class allows menus to be created easily.
00005 * Menus and submenus are represented by a menu path, in a form similar
00006 * to a file path name, separated by '/'s, starting from the root menu.
00007 * e.g. "a/b/c" represents the menu with menubutton labeled "a", and
00008 * cascade menus "b", and then "c".
00009 *
00010 * Cascade menus are automatically created. So for instance, a call to
00011 * add_command(b, "a/b/c", "test") will create the menubutton "a", and
00012 * submenus "a/b" and "a/b/c".
