This program was inspired by the behavior of the ``mouse documentation window'' on many Lisp Machine systems; as you type a function's symbol name as part of a sexp, it will print the argument list for that function. Behavior is not identical; for example, you need not actually type the function name, you need only move point around in a sexp that calls it. Also, if point is over a documented variable, it will print the one-line documentation for that variable instead, to remind you of that variable's meaning.
