+/**
+ * Mock ProPresenter looks API, for developing the ProPresenter Look module
+ * without the real thing.
+ *
+ *   node tools/pp-looks-mock.js [port]        (default 1601)
+ *     --every <seconds>   how often the live look changes (default 8)
+ *     --password <pw>     demand ?password=<pw> like a locked ProPresenter
+ *     --no-list           answer 404 for /v1/looks (an older ProPresenter)
+ *
+ * Point the module at host 127.0.0.1 and this port. Every few changes the
+ * live look is "modified by hand", so it matches no saved look.
