      TTX -- From OpenType To XML And Back
  
      If an input file is a TrueType or OpenType font file, it will be
         decompiled to a TTX file (an XML-based text format).
      If an input file is a TTX file, it will be compiled to whatever 
         format the data is in, a TrueType or OpenType/CFF font file.
  
      Output files are created so they are unique: an existing file is
         never overwritten.
  
      General options:
      -h Help: print this message.
      --version: show version and exit.
      -d <outputfolder> Specify a directory where the output files are
         to be created.
      -o <outputfile> Specify a file to write the output to. A special
         value of - would use the standard output.
      -f Overwrite existing output file(s), ie. don't append numbers.
      -v Verbose: more messages will be written to stdout about what
         is being done.
      -q Quiet: No messages will be written to stdout about what
         is being done.
      -a allow virtual glyphs ID's on compile or decompile.
  
      Dump options:
      -l List table info: instead of dumping to a TTX file, list some
         minimal info about each table.
      -t <table> Specify a table to dump. Multiple -t options
         are allowed. When no -t option is specified, all tables
         will be dumped.
      -x <table> Specify a table to exclude from the dump. Multiple
         -x options are allowed. -t and -x are mutually exclusive.
      -s Split tables: save the TTX data into separate TTX files per
         table and write one small TTX file that contains references
         to the individual table dumps. This file can be used as
         input to ttx, as long as the table files are in the
         same directory.
      -g Split glyf table: Save the glyf data into separate TTX files
         per glyph and write a small TTX for the glyf table which
         contains references to the individual TTGlyph elements.
         NOTE: specifying -g implies -s (no need for -s together with -g)
      -i Do NOT disassemble TT instructions: when this option is given,
         all TrueType programs (glyph programs, the font program and the
         pre-program) will be written to the TTX file as hex data
         instead of assembly. This saves some time and makes the TTX
         file smaller.
      -z <format> Specify a bitmap data export option for EBDT:
         {'raw', 'row', 'bitwise', 'extfile'} or for the CBDT:
         {'raw', 'extfile'} Each option does one of the following:
           -z raw
              * export the bitmap data as a hex dump
           -z row
              * export each row as hex data
           -z bitwise
              * export each row as binary in an ASCII art style
           -z extfile
              * export the data as external files with XML references
         If no export format is specified 'raw' format is used.
      -e Don't ignore decompilation errors, but show a full traceback
         and abort.
      -y <number> Select font number for TrueType Collection (.ttc/.otc),
         starting from 0.
      --unicodedata <UnicodeData.txt> Use custom database file to write
         character names in the comments of the cmap TTX output.
      --newline <value> Control how line endings are written in the XML
         file. It can be 'LF', 'CR', or 'CRLF'. If not specified, the
         default platform-specific line endings are used.
  
      Compile options:
      -m Merge with TrueType-input-file: specify a TrueType or OpenType
         font file to be merged with the TTX file. This option is only
         valid when at most one TTX file is specified.
      -b Don't recalc glyph bounding boxes: use the values in the TTX
         file as-is.
      --recalc-timestamp Set font 'modified' timestamp to current time.
         By default, the modification time of the TTX file will be used.
      --no-recalc-timestamp Keep the original font 'modified' timestamp.
      --flavor <type> Specify flavor of output font file. May be 'woff'
        or 'woff2'. Note that WOFF2 requires the Brotli Python extension,
        available at https://github.com/google/brotli
      --with-zopfli Use Zopfli instead of Zlib to compress WOFF. The Python
        extension is available at https://pypi.python.org/pypi/zopfli
