NAME

       qr - script to create QR codes at the command line

SYNOPSIS

       qr [--help] [--factory=FACTORY] [--optimize=OPTIMIZE] [--error-correction=LEVEL] [data]

DESCRIPTION

       This  script  uses  the  python  qrcode  module.  It  can take data from stdin or from the
       commandline and generate a QR code.  Normally it will output the QR code as ascii  art  to
       the  terminal. If the output is piped to a file, it will output the image (default type of
       PNG).

OPTIONS

        -h, --help
           Show a help message.

        --factory=FACTORY
           Full python path to the image factory class to create the image with. You can use  the
           following  shortcuts  to  the  built-in  image  factory  classes: pil (default), png (
           default if pillow is not installed), svg, svg-fragment, svg-path.

        --optimize=OPTIMIZE
           Optimize the data by looking for chunks of at least this many  characters  that  could
           use a more efficient encoding method. Use 0 to turn off chunk optimization.

        --error-correction=LEVEL
           The  error correction level to use. Choices are L (7%), M (15%, default), Q (25%), and
           H (30%).

        data
           The data from which the QR code will be generated.
