scan_naive_kernel.cu etc in CUDA 3.x? SDK example scan kernels in CUDA 2.3 cant find in CUDA 3

Does anyone know where the example CUDA C kernels for scan_naive etc have been moved to?
All I have been able to find so far is that scan_naive scan_workefficient and scan_best have been
“consolidated”. The version of scan_naive_kernel.cu I have came from CUDA 2.3 (which was wipped
when I upgraded to CUDA 3:-(

                        Thank you

To answer my own question the new code is in

/opt/cuda/sdk/C/src/scan

(at least for CUDA 3.1)
