title: wkhtmltopdf: Is it possible to merge PDF files?
body: <p>Using this library <a href="https://code.google.com/p/wkhtmltopdf/" rel="noreferrer">wkhtmltopdf</a>, is it possible to merge 2 pdf files. I need to generate a report and merge the report with some attached documents. </p>
  
  <p>Generation of report is done, converting from HTML to PDF. But I need to merge the resulting PDF with some other PDFs</p>
