tftopl [OPTIONS] tfm_name[.tfm] [pl_name[.pl]]
This manual page is not meant to be exhaustive. The complete documen-
tation for this version of TeX can be found in the info file or manual
Web2C: A TeX implementation.
The 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.
The pl_name is extended with .pl if it lacks a suffix. If pl_name is
not given, standard output is used. Likewise, tfm_name is extended with
.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,
tftopl uses the system default.
See tex(1) for the details of the searching.
The argument format specifies how character codes are output in
the PL file. By default, only letters and digits are output
using the C integer code (i.e., in ASCII); the others are output
in octal. (Unless the font's coding scheme starts with TeX math
sy or TeX math ex, in which case all character codes are output
in octal.) If format is ascii, all character codes that corre-
spond to graphic characters, besides the left and right paren-
theses, are output in ASCII. Finally, if format is octal, all
character codes are output in octal.
Without this option, tftopl operates silently. With it, a ban-
ner and progress report are printed on stdout.
