% print an afm file on the standard output
% usage is `fontname printafm' eg `/Times-Roman printafm'

% From the `dvitops' distribution, which included this notice:
% dvitops is not copyrighted; you can do with it exactly as you please.
% I would, however, ask that if you make improvements or modifications,
% you ask me before distributing them to others.

% Altered by d.love@dl.ac.uk to produce input for Rokicki's afm2tfm,
% which groks the format of the Adobe AFMs.

% Modified by L. Peter Deutsch 9/14/93:
%   uses Ghostscript's =only procedure to replace 'buf cvs print'.
% Modified by L. Peter Deutsch 9/6/95:
%   uses Ghostscript's .shellarguments facility to accept the font name
%     on the command line.

% Altered my master@iaas.msu.ru to work with fonts of more than 256 glyphs
% and avoid FSType output. Also print a comment with UniqueID of the font.
