-POSITION is a position specification. This is either a mouse button
-event or a list ((XOFFSET YOFFSET) WINDOW) where XOFFSET and YOFFSET
-are positions in pixels from the top left corner of WINDOW's frame
-\(WINDOW may be a frame object instead of a window). This controls the
-position of the center of the first line in the first pane of the
-menu, not the top left of the menu as a whole. If POSITION is t, it
-means to use the current mouse position.
-
-MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
-The menu items come from key bindings that have a menu string as well as
-a definition; actually, the \"definition\" in such a key binding looks like
-\(STRING . REAL-DEFINITION). To give the menu a title, put a string into
-the keymap as a top-level element.
-
-If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
-Otherwise, REAL-DEFINITION should be a valid key binding definition.
-
-You can also use a list of keymaps as MENU. Then each keymap makes a
-separate pane. When MENU is a keymap or a list of keymaps, the return
-value is a list of events.
-
-Alternatively, you can specify a menu of multiple panes with a list of
-the form (TITLE PANE1 PANE2...), where each pane is a list of
-form (TITLE ITEM1 ITEM2...).
-Each ITEM is normally a cons cell (STRING . VALUE); but a string can
-appear as an item--that makes a nonselectable line in the menu.
-With this form of menu, the return value is VALUE from the chosen item.
-
-If POSITION is nil, don't display the menu at all, just precalculate the
-cached information about equivalent key sequences. */)
