# Description
# -----------
# Command line interface for the GUT unit testing tool. Allows you to run tests
# from the command line instead of running a scene. Place this script along with
# gut.gd into your scripts directory at the root of your project. Once there you
# can run this script (from the root of your project) using the following command:
# godot -s -d test/gut/gut_cmdln.gd
#
# See the readme for a list of options and examples. You can also use the -gh
# option to get more information about how to use the command line interface.
#
# Version 6.8.2
