+This program converts bitmap fonts to a homegrown outline format, bezier
+(BZR).  The program `bzrto' converts that format to something usable for
+typesetting.
+
+We used two main sources in writing the program:

+  title = "Phoenix: An Interactive Curve Design System Based on the
+           Automatic Fitting of Hand-Sketched Curves",

+
+We had access to the code for Phoenix, thanks to Philip, but none of our
+code is based on his (mostly because his task was allow interactive
+sketching, and ours to fit bitmap characters, and the two require
+different data structures).  The general outline of the fitting
+algorithm does come from Phoenix.
+
+We also found this article helpful:
