  ----- File:        type1afm.c 
  ----- Author:      Rainer Menzner (Rainer.Menzner@web.de)
  ----- Date:        2002-11-27
  ----- Description: This file is part of t1lib. The program type1afm 
                     extracts metrics information from Type 1 font files
                 and dumps it to  afm files.

                     their rasterizer freely available.
                 Also thanks to Piet Tutelaers for his ps2pk, from
                 which I took the rasterizer sources in a format
                 independent from X11.
                     Thanks to all people who make free software living!
