          Use own package for starting timetagger web application.

          The ${literalExpression ''pkgs.timetagger''} package only provides a
          "run.py" script for the actual package
          ${literalExpression ''pkgs.python3Packages.timetagger''}.

          If you want to provide a "run.py" script for starting timetagger
          yourself, you can do so with this option.
          If you do so, the 'bindAddr' and 'port' options are ignored.
