.SH NAME
tftopl \- convert TeX font metric (tfm) files to property lists
.SH SYNOPSIS

.RI [ pl_name [ \fB.pl\fP ]]

.SH DESCRIPTION
This manual page is not meant to be exhaustive.  The complete
documentation for this version of \*(TX can be found in the info file
or manual
.IR "Web2C: A TeX implementation" .
.PP
The
.B tftopl
program translates a (program-oriented) font metric file to a
(human-oriented) property list file.  Thus, you can edit the contents of
the TFM files, if the font designer has not done his or her job
properly, or if you're encountering strange difficulties, or if you're
just curious.  It also serves as a TFM-file validating program, i.e., if
no error messages are given, the input file is correct.
.PP
The
.I pl_name
is extended with
.B .pl
if it lacks a suffix.
If
.I pl_name
is not given, standard output is used. Likewise, 
.I tfm_name
is extended with
.B .tfm
if it lacks a suffix.  Also, path searching is done for the TFM file
using the environment variable TEXFONTS.  If that is not set, 
.B tftopl
uses the system default.
.PP
See
.BR tex (1)
for the details of the searching.

.SH OPTIONS
.TP
.BI \-charcode-format= format
The argument
.I format
specifies how character codes are output in the PL file.  By
default, only letters and digits are output using the
.B C
integer code (i.e., in ASCII); the others are output in octal.  (Unless
the font's coding scheme starts with
.B "TeX math sy"
or
.BR "TeX math ex" ,
in which case all character codes are output in octal.)  If
.I format
is
.BR ascii ,
all character codes that correspond to graphic characters, besides the
left and right parentheses, are output in ASCII.  Finally, if
.I format
is
.BR octal ,
all character codes are output in octal.
.PP
.TP
.B \-verbose
Without this option,
.B tftopl
operates silently.  With it, a banner and progress report are printed on
.IR stdout .
