--   Haskell bindings for libqrencode. Libqrencode is a C library for
--   encoding data in a QR Code symbol, a kind of 2D symbology that can be
--   scanned by handy terminals such as a mobile phone with CCD. The
--   capacity of QR Code is up to 7000 digits or 4000 characters, and is
--   highly robust.
