Nice work Chris .. doesn't work on all my PDF's, though:

    j@w1x8-dev:~/Documents/PDF Documents {}
    $ pdfx xhyve\ –\ Lightweight\ Virtualization\ on\ OS\ X\ Based\ on\ bhyve\ _\ pagetable.pdf
    Traceback (most recent call last):
      File "/usr/local/bin/pdfx", line 9, in <module>
    load_entry_point('pdfx==1.0.1', 'console_scripts', 'pdfx')()

If you want some sample PDF's on which it is borked, just let me know .. in the meantime I'm using pdf_scraper for most of these ..
