I'd assume Greg uses it in his Windows builds, for example?

    Ya, I need to be able to generate executables via makefiles that detect
    failures from fluid via exit codes; Windows apps invoked from a Makefile
    immediately run 'in the background' and don't ever return exit codes
    indicating failures from code generation (-c flag).

    Also, on headless machines there's no way to see the record of failure
    in the error logs of non-console apps. For instance a permission problem
    reading the .fl file, or a write problem for the .cxx/.h files due to
    code directory permissions or network file access issues.
