// TODO: Fix this for some web servers

// If your script lives in the web root folder use a / or leave it empty

// Do not forget to edit the basepath in .htaccess if you are on apache
// Route::run('/api/v1');

// Enable case sensitive mode and trailing slashes by setting both to true
// Route::run('/', true, true);
