.TH GFTYPE 1 "7 Jan 92"
.SH NAME
gftype - translate a generic font file for humans to read
.SH SYNTAX
.B gftype
[-m] [-i] gf_file_name [output_file_name]
.SH DESCRIPTION
The
.I gftype
program
translates a GF (generic font) file output by, for example, 
.BR mf (1),
to a file that humans can read.
It also serves as a GF file-validating
program (i.e., if
.I gftype
can read it, it's correct) and as an example of a GF-reading
program for other software that wants to read GF files.
.PP
The
.I gf_file_name
on the command line must be complete. Because
the resolution is part of the extension, it would not make
sense to add on a default extension as is done with TeX or
DVI-reading software. If no
.I output_file_name
is specified, the output goes to
.IR stdout .
.SH OPTIONS
The output file includes a symbolic listing of the GF commands, if
.I -m
is given on the command line, 
and bitmap images of the characters, if
.I -i
is specified.
.SH ENVIRONMENT
.I gftype
looks for
.I gf_file_name
first in the current directory.  If it is not present there, it uses the
environment variable GFFONTS.  If that is not set, it uses the variable
TEXFONTS.  If this is not set, it uses the system defaults:
.br
TEXFONTS:
.BR /usr/local/lib/tex/fonts/tfm:. ,
.br

technical report, available from the TeX Users Group.
Paul Richards originally ported it to Unix.
