Thanks! The patch is located at:
http://www.rtems.org/ftp/pub/rtems/people/chrisj/examples-v2-waf.diff
I haven't tried it, but if the patched examples-v2-waf makes executables, it might be feasible to port simple applications using this method...

There needs to be a publically available tutorial for how to maintain a Waf-based build-system (I think its inadvisable that only a few people should have keys to the build-system kingdom)...

http://www.rtems.org/ftp/pub/rtems/people/chrisj/rtems-waf/ looks promising, I'll give it a try next weekend!

I'll be probably work helping with on porting rtems-testing to python, for a few weekends, to learn more about both...
Thanks for showing us this!
