I agree. But I am not sure if all of this need to be addressed at the
first shot at a tool. I spend some time reading docs for bbv2 and mpc
now, so soon I will have better understanding of formats and semantics.

I guess this can be done in two steps
1. Translates Jamfiles to mpc files (as OCI is now offering
2. MPC generate workspace/project files (as supported by in existing MPC)
This may be an ok solution.
