echo <<<EOD
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)
