Help:

   -h              - show this message
   -o {output}     - specify a file or directory for the PDF output
   -x              - open pdf when finished

Examples:

   pdf -o /path/to/output.pdf ~/path/to/input.doc
   pdf -o ~/my_pdf_directory *.ppt
   pdf input.rtf

Note: Runs significantly faster when OpenOffice is running.
