% This is a PostScript program for making an AFM file from
% PFB / PFA and (optionally) PFM files.
%
% Written in BOP s.c., Gda\'nsk, Poland
% e-mail contact: B.Jackowski@GUST.ORG.PL
% version 0.5 (18 XII 1997)
% version 0.55 (11 III 1998) -- unlimited number of chars in a font
% version 1.00 (27 III 1998) -- scanning PFM subdirectory added,
% code improved; version sent to LPD
% version 1.01 (1 II 2000) -- message changed
% Usage:
% gs [-dNODISPLAY] -- pf2afm.ps disk_font_name
%
% The result is written to the file disk_font_name.afm, provided such
% a file does not exist; otherwise program quits.
%
% The font can be either *.pfa or *.pfb; if no extension is supplied,
% first disk_font_name.pfb is examined, then disk_font_name.pfa.
% Moreover, if there is a *.pfm file in the same directory or in the
% subdirectory PFM, i.e., disk_font_name.pfm or PFM/disk_font_name.pfm,
% kern pairs from it are extracted, as well as additional font
% parameters, usually absent from Type 1 fonts.
% Tribute:
% The program is based on James Clark's <jjc@jclark.uucp> printafm.ps
% (with alterations by d.love@dl.ac.uk and L. Peter Deutsch) from
% Ghostscript 5.10 distribution.
