DESCRIPTION

13       Libqrencode  is a library for encoding data in a QR Code symbol, a kind
14       of 2D symbology that can be scanned by handy terminals such as a mobile
15       phone  with  CCD.  The capacity of QR Code is up to 7000 digits or 4000
16       characters, and has high robustness.
17
18       Qrencode is a utility software using libqrencode to encode string  data
19       in a QR Code and save as a PNG image.
