+# This script is used to prepare the patch release by generating patches for automatic releases.

+# The release driver should also ensure that the patches are generated successfully and the PR is created successfully.

+# What this script does:
+#   - Checks out a new release branch, 'release/patch/$currentDate'
+#   - Runs the script to generate patches for automatic releases
