Too late, I already did.  ;)  Check externals/build/src.  What do you  
mean by helper files?

I totally agree, keep it flexible and open.  [a-zA-Z0-9_] sounds good  
to me.

It would be nice to have filenames and setup functions treated  
separately, so that filenames would remain human-readable.   Filenames  
would only need to substitute:

["/\*?<>|:]

Here's a little breakdown of the relevant filesystems:
