shuttle component MIA

I have a contour shuttle pro and would like to try the shuttle component to implement it. I found the doc on that component, but the component itself is not in the current 2.7.8 distro and not a hint of where to find it nor how to add add it to my install.

Here is the doc, it was just updated this month, so its not something obsolete.
linuxcnc.org/docs/devel/html/drivers/shuttle.html

Also, there is a sample hal file using the component on the current release BUT again, the component itself is not there.

Any help on finding the component and how to install it would be much appreciated. I am somewhat a novice on linux.

Thanks,
George

(PS, this component "shuttlexpress" document appears nearly identical, EXCEPT it does not support the shuttlepro model as the other missing component does)
