Just a small update: 542 classes are successfully generated (and buildable). 132+ are left to go.
I've ran into a few issues where the interface files (from which the xml is built) are not in sync with the code. So there might be missing types definitions, or wrong types in methods, etc. But these can be worked around by adding extra type definitions in the generator (IOW there's no need to manually touch the .cpp files by hand). So wxc won't be done by this week, but it's progressing pretty good so far. Stay tuned..
