+#
+#   For the version 3.1 and higher:
+#
+#     This script updates the schema IDs in the following YAML files:
+#
+#       schemas/v{major}.{minor}/schema.yaml
+#       schemas/v{major}.{minor}/schema-base.yaml
+#
+#     and generates the following JSON files from the updated YAML files:
+#
+#       schemas/v{major}.{minor}/schema.json
+#       schemas/v{major}.{minor}/schema-base.json
+#
+#   For the version 3.0:
+#
+#     This script updates the schema ID in the following YAML file:
+#
+#       schemas/v{major}.{minor}/schema.yaml
+#
+#     and generates the following JSON file from the updated YAML file:
+#
+#       schemas/v{major}.{minor}/schema.json
+#
+#   For versions older than 3.0:
+#
+#     This script does not support versions older than 3.0.
