+# Pre-commit hook for verifying that generated library modules match
+# their EXPECTED content. Library modules are generated from fragments
+# under the 'roles/lib_(openshift|utils)/src/' directories.
+#
+# If the attempted commit modified files under the
+# 'roles/lib_(openshift|utils)/' directories this script will run the
+# 'generate.py --verify' command.
+#
+# This script will NOT RUN if module source fragments are modified but
+# not part of the commit. I.e., you can still make commits if you
+# modified module fragments AND other files but are not comitting the
+# the module fragments.
+
+# Did the commit modify any source module files?
