+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.
