Jocks Client provide you a simple and free way to downloads jocks stream from Jocks Server running
all over the internet! You just need to know on what server you want to log on.
Run it like that :

        python jocks_client --function=<the_function_you_want_to_use> --args=<the specifications you want to use with the function>

This command will try to connect on a server located to localhost:11444 as default, you can of course choose the location of the server yourself :

        python jocks_client --host=<address of the server host> --port=<the port the server use to provide jocks> --function=<function> --arg=<args>

For more informations about the functions to use to manage your jocks stream, see the README file!

        Enjoy!
