build questions

[Daniel Goertzen]

Hello everyone.  I'm trying to learn the Erlang build system with hopes 
of cleaning things up a bit and making cross compiling easier.  I have a 
number of questions:

1. Are OSE and VxWorks still well supported targets?
2. Can someone tell me about shared and hybrid emulators?
3. Are purify, quantify, and purecov still used?
4. Is anybody actively working on the build system right now?

Any other advice?

Thanks,
Dan.
