Troff character widths???

[Jerold J. Colwell]

I'm trying to extract plain troff character widths from the
files in /usr/lib/font.  Does anyone know the format of these
files, or at least a reference to point me in the right
direction?  Any help would be greatly appreciated.

Please e-mail any suggestions.

Jerry
