+# OVERVIEW
+# --------
+#
+#   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
+#
+# USAGE
+# -----
+#
+#   update-schema-id
+#     --version VERSION   # -v VERSION (required)
+#     --date DATE         # -d DATE
+#     --dry-run           # -n
+#     --quiet             # -q
+#     --help              # -h
+#
+# EXAMPLE
+# -------
+#
+#   ./scripts/update-schema-id -v 3.1
+#
+#   If the above command line is executed on May 7, 2024, the following
+#   external commands are invoked by the script.
+#
+#     ex -s -c '/^$id:/s/^.*$/$id: '\''https:\/\/spec.openapis.org\/oas\/3.1\/schema\/2024-05-07'\''/' \
