running under Perl version 5.44.0.

Usage: hackos2 [-OPTIONS [-MORE_OPTIONS]] [--] [PROGRAM_ARG1 ...]

The following single-character options are accepted:
	With arguments: -c -d -f -n -p -t -u -v -x -w

For more details run
    perldoc -F /usr/bin/hackos2
  [Now continuing due to backward compatibility and excessive paranoia.
   See 'perldoc Getopt::Std' about $Getopt::Std::STANDARD_HELP_VERSION.]
Usage:
      HACKOS2 [-c hex] [-d directory] [-f fsSelection] [-p hex] [-q]
              [-t num] [-u hex] [-w width] <infile> <outfile>

    Hacks the OS/2 table of a ttf file copying from infile to outfile.

Options:
      -c      change codepage information (a 64 bit hex number)
      -d      specifies output directory for processing multiple files. In which
              case <outfile> is not used and <infile> may be a list including
              wildcards.
      -f      fsSelection value (16 bit hex) (e.g. 4240 for Thai fonts)
      -n      sets usFirstCharIndex given a hex value
      -p      change panose info
                  (10 bytes of hex in reverse order: 0A090807060504030201)
      -q      Quiet mode (do not list names as they are processed)
      -t      Sets fsType (embedding) information (decimal)
      -u      change unicode info (a 128 bit hex number)
      -v      sets vendor tag to the first 4 chars of the string
      -w      set average char width (decimal)
      -x      sets usLastCharIndex given a hex value

    For example, to convert a Win3.1 ANSI font to Win95 use the following:

      hackos2 -c01 -u03 old.ttf new.ttf

    or for a Symbol font use:

      hackos2 -c80000000 -u0 old.ttf new.ttf

    Or to revert:

      hackos2 -cnone other.ttf new.ttf
