# This script loads scripts so you can see a list of all the warnings that
# are generated by your scripts.
# 	* Sets all ERROR warnings to WARN
#	* Loads all scripts in "res" and all subdirectories (by default)
#	* If you specify a path after the script it will load that path instead
#
# You must run this script with the -d option or errors/warnings are not
# printed by Godot.

# Example:
# 	godot -d -s scratch/demo_generate_all_warnings.gd
#	godot -d -s scratch/demo_generate_all_warnings.gd res://addons/my_addon
