[Ves] VES on the Raspberry Pi

[John Donovan]

Hi Pat,
Thanks for the quick reply. I'll get those files in and compiling
later. The project I am involved in is in its early stages, but I am
happy to hack on the VES source code to improve support for the Pi and
submit pull requests or patches if that would be of help.

Regards,
John
