Where are Pin Definitions in the Joystick library?

I trying to build a custom joystick (just x-y and 1 button) and using the Joystick library created by Matthew Heironimus.

So far I've been unable to locate what pins the pots should be tied to. I've not found anything in the .h and none of the examples show this.

Any ideas where they are shown or how to define them using this lib? :o

The library doesn't use any pin numbers. If you want a pin to provide input you have to read from the pin and call a libarry function to set the joystick position based on that input. Sadly, none of the 'example' sketches do that. They just move the controls in a fixed pattern.
