Hello,
  I'm doing some experiments trying to use the DMD front-end as a library to generate code (Why3ML) that can be used in a formal verification tool. However, documentation is a little sparse. I've looked through the examples in dmd/src/examples, and they were a fine starting point but now I'm getting to the point where I need to snag function arguments, types, and contracts out of the AST.

  Can anybody point me to some good examples of other projects that use the DMD front-end that I might be able to reference?

Thanks,
  Doc
