Usage: {$_SERVER["argv"][0]} [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 '$default_paper_size'
 -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 printed to stdout.
 -t             Comma separated list of debugging types (page-break,reflow,split)
