+Each argument to this macro must be a list of a key and a value.
+
+  Keys:		  Values:		Corresponding variable:
+
+  verbose	  t, nil		byte-compile-verbose
+  optimize	  t, nil, source, byte	byte-optimize
+  warnings	  list of warnings	byte-compile-warnings
+  file-format	  emacs18, emacs19	byte-compile-emacs18-compatibility
+
+The value specificed with the `warnings' option must be a list, containing
+some subset of the following flags:
+
+  free-vars	references to variables not in the current lexical scope.
+  unused-vars	references to non-global variables bound but not referenced.
+  unresolved	calls to unknown functions.
+  callargs	lambda calls with args that don't match the definition.
+  redefine	function cell redefined from a macro to a lambda or vice
+		versa, or redefined to take a different number of arguments.
+
+If the first element if the list is `+' or `-' then the specified elements 
+are added to or removed from the current set of warnings, instead of the
+entire set of warnings being overwritten.
+
+For example, something like this might appear at the top of a source file:
+
+    (byte-compiler-options
+      (optimize t)
+      (warnings (- callargs))		; Don't warn about arglist mismatch
