  46  * Display command line usage:
  47  *
  48  * Usage: ./dompdf.php [options] html_file
  49  *
  50  * html_file can be a filename, a url if fopen_wrappers are enabled, or the '-'
  51  * character to read from standard input.
  52  *
  53  * Options:
  54  *  -h             Show this message
  55  *  -l             list available paper sizes
  56  *  -p size        paper size; something like 'letter', 'A4', 'legal', etc.  The default is
  57  *                 'letter'
  58  *  -o orientation either 'portrait' or 'landscape'.  Default is 'portrait'.
  59  *  -b path        set the 'document root' of the html_file.  Relative urls (for
  60  *                 stylesheets) are resolved using this directory.  Default is the
  61  *                 directory of html_file.
  62  *  -f file        the output filename.  Default is the input [html_file].pdf.
  63  *  -v             verbose: display html parsing warnings and file not found errors.
  64  *  -d             very verbose: display oodles of debugging output: every frame in the
  65  *                 tree is printed to stdout.
