+/**
+ * Class for managing routes.
+ *
+ * Routes connect a URL path to a module that will handle requests to that
+ * path.
+ *
+ * For example by registering a route like this:
+ *
+ * ```php
+ * Route::register(
+ *     __DIR__ . '/Mod_Myroute.php',
+ *     'myroute'
+ * );
+ * ```
+ *
+ * Hubzilla will direct requests to the '/myroute' URL path to the 'Myroute'
+ * controller located in the '/Mod_Myroute.php' file in the same directory as
+ * the file this code was called from.
+ *
+ * Routes are stored persistently, so this function will typically be called from
+ * the `<addon>_load()` function if called from an addon. Accordingly, the route must
+ * be unregistered when no longer needed, like this:
+ *
+ * ```php
+ * Route::unregister(
+ *     __DIR__ . '/Mod_Myroute.php',
+ *     'myroute'
+ * );
+ * ```
+ *
+ * This will typically be called from the `<addon>_unload()` function in an addon.
