want and nant

I have been using the want build tool to manage a resonable size delphi project.
However I have taken over support of some related C# code.
I am investigating porting the delphi specific tasks (delphi compiler, the resource compiler and dunit) to nant. So far the hardest part has been getting each of them to build in the IDE.
Once this is done I will be able to create a unified build tool.
