Hi there - author of `jc` here. I originally intended to have auto-detection but put that on the backburner to focus on creating parsers, especially after introducing the magic syntax.

I did implement auto-detection for `/proc` file parsers so you can just do:

    $ cat /proc/foo | jc --proc

or

    $ jc /proc/foo

But you can specify each procfile parser directly if you want to as well.
