Yes. With preference given to the drscheme ones.

No, the "don't save any compiled files for anything in the collects

I'll leave this one to Matthew to try to explain. I think you're
probably wrong, but I'm not sure precisely why. It is a big hairy

can handle setting various parameters and loading the libraries into
drscheme) this line of inquiry won't go anywhere.
