Very nice!

I tried parsing the "DFUnit TestRunner.src" project from "DFUnit Example Workspace" https://github.com/olaeld/DFUnit

It seems the following line raises an "Illegal characters in path" exception:
Use "DFUnit Precompile.pkg"

Would you consider open sourcing your project? By putting it on GitHub, for example, it would be easier for the rest of us to contribute.
