dvibit is a program allowing one to preview a DVI file on a BBN BitGraph
terminal.

To install dvibit:

- decide where to put the font bit maps and copy the contents of
  ./fonts to that location.  Update the Makefile definition for
  FONTAREA to point to that location.  Don't forget the trailing
  '/'.  The bitmaps are in ./pxl118.
- make dvibit
- put the executable somewhere reasonable.
