Someone can correct me if I'm wrong, but I believe all the current documentation for FIRST C++ is on the WPI FIRST Forge site. For setting up Windriver, check out the C++ Getting Started Guide on
http://firstforge.wpi.edu/sf/docman/..._documentation
P.S. I tried to post this twice already, but it somehow is getting removed. I'm not getting any message, so I'm trying one more time. My bad if I'm not supposed to be resubmitting or if it shows up several times.
