If you don't you might find an answer [here] (http://silex.sensiolabs.org/doc/master/web_servers.html)

Create a bin directory and put the backend binary in it. To build the backend see [athorrent-backend] (https://github.com/Athorcis/athorrent-backend)

And make sure the athorrent directory and all its subdirectories and files are owned by the user who run the webserver.
