/**
 * Display command line usage:
 *
 * Usage: ./dompdf.php [options] html_file
 *
 * html_file can be a filename, a url if fopen_wrappers are enabled, or the '-'
 * character to read from standard input.
 *
 * Options:
 *  -h             Show this message
 *  -l             list available paper sizes
 *  -p size        paper size; something like 'letter', 'A4', 'legal', etc.  The default is
 *                 'letter'
 *  -o orientation either 'portrait' or 'landscape'.  Default is 'portrait'.
 *  -b path        set the 'document root' of the html_file.  Relative urls (for
 *                 stylesheets) are resolved using this directory.  Default is the
 *                 directory of html_file.
 *  -f file        the output filename.  Default is the input [html_file].pdf.
 *  -v             verbose: display html parsing warnings and file not found errors.
 *  -d             very verbose: display oodles of debugging output: every frame in the
 *                 tree is printed to stdout.
 *  -t             comma separated list of debugging types (page-break,reflow,split)
 *  -r             write the render time to the log file
