title: PDF processing library in Erlang
body: <p>I am looking for a PDF processing library written in Erlang, but I was unable to find any yet. <a href="http://www.sics.se/~joe/erlguten-2.1/erlguten.html" rel="noreferrer">ErlGuten</a>, the only library I found could only generate PDFs not process them.
  Anyone aware of such library?</p>
