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).

image with. You can use the following shortcuts to the
built-in image factory classes: pil (default), pymaging,
svg, svg-fragment, svg-path.

-
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.
