# This script is a simple wrapper which prefixes each i3status line with custom
# information. It is based on:
# https://github.com/i3/i3status/blob/master/contrib/wrapper.py
#
# In ~/.i3status.conf, add the following line:
#     output_format = "i3bar"
# in the 'general' section.
# Then, in ~/.config/i3/config or ~/.config/sway/config add:
#     status_command i3status | my-i3status.py
# in the 'bar' section.  Make sure my-i3status.py is in $PATH.
