[XeTeX] Checking if a font exists

[Alan Munn]

Wow, I never imagined my question would produce such a flurry of  
responses (and since I was without internet access for a mere 18  
hours, I've not been able to respond.)  Thanks to everyone for their  
suggestions; as others have noted, Jonathan's approach is certainly  
the kind that I would prefer to use, especially since I have no  
knowledge of how Windows machines work...

Thanks again to everyone.

Alan
