I'm not sure. I've never used that.

The macro just needs a couple of objects and a couple of vectors to tell it 
how the object is positioned and oriented. The main object is a shell that 
it can trim to shape to form the hairline object. This can actually just be 
a slice of the main object or just the difference between two spheres to 
give a shell that fairly closely maps to the skull. It uses trace to 
randomly find hair starting positions on this object. The other object is 
the real anatomy object that it uses to trace the hairs down over. It 
follows some simple rules to respond to gravity, curl and stuff, then it 
uses trace to make sure it doesn't penetrate the surface of the anatomy 
object.

It's the same basic hair macro that I used to generate a couple of 
animations back in 2006.
