+% 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:
+% $Id: pf2afm.ps 6300 2005-12-28 19:56:24Z giles $
+% 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.
