# Patching is needed here for the following reasons:
# * `sphinx-build` in nixpkgs is not a Python file but a wrapper shell script
# * importing the `constants` package from Kitty has a side effect that it
#   creates the user configuration directory. This package gets imported
#   while sphinx scans the code for documentation strings.
#
 # You can set these variables from the command line.
