Wayfinder can work through a Command Line Interface, just head to the www folder and execute your commands from there. Thanks to a symlink included in the project, you can invoke Wayfinder from the command line like this:
php Wayfinder
Just like the browser, the CLI will default to using the / route or you can specify your own by passing a URI as an argument:
php Wayfinder /user/profile/cafu
Routes are Wayfinder is handled the same way by both browsers and the CLI.
