[XeTeX] IM Fell Type and XeTeX

Sat Feb 14 22:43:04 CET 2009

Well, I guess that Igino Marini has settled these questions for us.

Of course he has the right to impose whatever restrictions he likes, 
consistent with copyright law, and his reasons for doing so seem valid 
enough. My own preference is not to use products licensed in this way. 
Too bad: I was thinking of using this nice font family.
