+///
+/// `FoxxController#around(path, callback)`
+///
+/// The around function takes a *path* on which it should watch and a function
+/// that it should execute around the function which normally handles the
+/// route. If you do omit the path, the function will be executed before each
+/// request, no matter the path.  Your function gets a Request and a Response
+/// object and a next funcion, which you must call to execute the handler for
+/// that route.
+///
+/// @EXAMPLES
+///
+/// ```js
+/// app.around('/high/way', function(req, res, opts, next) {
+///   //Do some crazy request logging
+///   next();
+///   //Do some more crazy request logging
+/// });
+/// ```
