// Package rc implements a remote control server and registry for rclone
//
// To register your internal calls, call rc.Add(path, function). Your
// function should take and return a Param. It can also return an
// error. Use rc.NewError to wrap an existing error along with an
// http response type if another response other than 500 internal
// error is required on error.
