Yes, the previous version caught the ":" in the drive letter specification.

Yes, it works. I had thought of testing for "if OS == win" sort of stuff 
instead of testing for the presence of ";" or ":". But it appears that 
Python has the foresight to provide os.pathsep. I learnt a bit more and 
love Python a bit more. :-)

You deserve much thanks for developing such a nice package.

An afterthought: perhaps an EPS backend instead of/additional to a PS 
backend would be more convenient for inclusion into publications. I 
know very little about postscript programming so I don't know what's the 
effort involved, though.
