+apply-release-changes.py - Cross-platform script to replace main with a specified release version in YML files
+
+This script performs two replacements in YML files in .github/workflows/:
+1. Replaces @main with @release/VERSION
+2. Replaces 'test-infra-ref: main' with 'test-infra-ref: release/VERSION'
+
+Usage:
+  python apply-release-changes.py VERSION
+
+Example:
+  python apply-release-changes.py 2.7
