+;; This loop is the guts for non-standard modes which retain control
+;; until some event occurs.  It is a `do-forever', the only way out is to
+;; throw.  It assumes that you have set up the keymap, window, and
+;; everything else: all it does is read commands and execute them -
+;; providing error messages should one occur (if there is no loop
+;; function - which see).  The required argument is a tag which should
+;; expect a value of nil if the user decides to punt. The
+;; second argument is a prompt string (defaults to "->").  Given third
+;; argument non-nil, it INHIBITS quitting unless the user types C-g at
+;; toplevel.  This is so user can do things like C-u C-g and not get
+;; thrown out.  Fourth argument, if non-nil, should be a function of two
+;; arguments which is called after every command is executed.  The fifth
+;; argument, if provided, is the state variable for the function.  If the
+;; loop-function gets an error, the loop will abort WITHOUT throwing
+;; (moral: use unwind-protect around call to this function for any
+;; critical stuff).  The second argument for the loop function is the
+;; conditions for any error that occurred or nil if none.
