  # * dparse2 is a "Temp fork for Python 2 support", but pdfminer requires
  # Python 3, so it's "fine" to leave dparse2 unpackaged and use the "normal"
  # version
  # * ftfy was pinned for similar reasons (to support Python 2), but rather than
  # packaging an older version, I figured it would be better to remove the
  # erroneous (at least for our usage) version bound
  # * bitarray's version bound appears to be unnecessary for similar reasons
