       If you need to generate a QR picture using command line tool. I would
       recommend libqrencode.
       
       .Bd -literal -offset indent
       qrencode -o file.png 'some text'
       .Ed
       
       It's also possible to display the QR code inside the terminal with
       the following command.
       
       .Bd -literal -offset indent
       qrencode -t ANSI256 'some text'
