Usage: %s [options] <source uri> [<stylesheet uri>]...
Options:
  -i                Ignore stylesheet processing instructions in the

  -v                Validate the input file as it is being parsed.
  -D<name>=<value>  Bind a top-level parameter, overriding any binding in
                     the stylesheet.
  -o<filename>      Specify a filename for the output.  This file will be
                     overwritten if present.

Note: if you use "-" as the name of the source document, the source will
instead be read from standard input.
