# -*- python -*-

# This example can be used to name a mode you want to use,
# and load the script, without having the use Blueshift's -c
# option and give a pathname. You will only need to give a
# filename. In this example, those modes are installed in
# the directory `$XDG_CONFIG_HOME/blueshift-modes`, and the
# default mode is named `default`.
