title: Multilingual flask application
body: <p>Is there a preferred way to make a Flask application multilingual? Ideally, the solution would enable to <code>@app.route</code> the same view to use different urls for each languages, like <code>@app.route(en='/staff/', fr='/equipe/)</code>. I'm pretty confident I could hack something like that together, but an existing library would sure save me some time. Thanks.</p>
