+"""
+This script automates the creation of a release branch for the NGO package.
+
+It performs the following steps:
+1. Creates a new release branch named 'release/<version>'.
+2. Executes the release.py script that prepares branch for release by
+updating changelog and ValidationExceptions.
+3. Commits all changes made by the script.
+4. Pushes the new branch to the remote repository.
