usage: xmlto [OPTION]... FORMAT XML
OPTIONs are:
  -v              verbose output (-vv for very verbose)
  -x stylesheet   use the specified stylesheet instead of choosing one
  -m fragment     use the XSL fragment to customize the stylesheet
  -o directory    put output in the specified directory instead of
                  the current working directory
  -p postprocopts pass option to postprocessor
  --extensions    turn on stylesheet extensions for this tool chain
  --noautosize    do not autodetect paper size via locales or paperconf
  --noclean       temp files are not deleted automatically
                  (good for diagnostics)
  --noextensions  do not use passivetex/fop extensions
  --profile       use profiling stylesheet
  --searchpath    colon-separated list of fallback directories
  --skip-validation
                  do not attempt to validate the input before processing
  --stringparam paramname=paramvalue
                  pass a named parameter to the stylesheet from the
                  command line
  --with-fop      use fop for formatting (if fop available)
  --with-dblatex  use dblatex for formatting (if dblatex available)

Available FORMATs depend on the type of the XML file (which is
determined automatically).
