+# Python script to convert a Godot project using Spine .json skeleton files to use the new
+# extension .spine-json instead.
+#
+# Usage: python convert.py path/to/godot/project
+#
+# Note: ensure you have created a backup of your Godot project before running this script.
+#
+# The script will traverse all .json, .tscn, and .tres files in the directory recursively.
+#
+# For each .json file, it will rename the file to .spine-json and remove the .json.import file.
+# Upon reloading the the project in Godot, the file will be re-imported and the a .spine-json.import
+# file will be created in place of the .json.import file.
+#
+# For each .tscn or .tres file, it will replace the .json suffix in external resources of type
+# SpineSkeletonFileResource with the new suffix .spine-json.
