title: Mass PDF form fill
body: <p>I need to fill in a single PDF template multiple times and concat the results. When I say multiple, I mean up to a few hundred times, potentially over one thousand.</p>
  
  <p>I can do this with <code>pdftk fill_form</code>, one by one, and then use <code>pdftk cat</code>. We can parallelize this fairly easily.</p>
  
  <p><strong>I'm curious if this is the only option, or if there is a piece of software (Linux + OSX, command line) that will allow me to say "take this template, and these sets of fields, fill out this form, and concat the files" so I can avoid doing every one individually.</strong> Then again, if something does exist, but it's not any faster than just doing the <code>fork</code> parallelization method, then it's probably not worth it.</p>
