arduino fake keyboard shield schematic?

[blackbeard]

i've seen a circuit online that allows the arduino to interface with with a computer as if it were a usb keyboard. the source code was easy enough to find but the schematic for the shield (which looks brutally simple) is really hard to find. does anyone have this schematic or know how to connect it? so far the only source i've found for the schematic is a book called "practical arduino" which will set me back $30! here's the info i've found on it so far

"Both d+ and d- ports must be wired to the same pin"

Looks like they are using the V-USB style of USB interfacing. See here:

Download the source code zip file and inside there is an image file of the schematic.
