+##   o USE_LEGACY= (default)
+##       - bridge logic: support existing behavior.
+##       - helmlint.sh contains hardcoded branch='origin/opencord'
+##   o TODO:
+##       - infer values from repository checkout on disk.
+##       - parameterize helmlint.sh
+##       - use simple flags to toggle behavior:
+##           MASTER_BRANCH=1  || --branch master (default)
+##           LOCAL_BRANCH=1   || --branch local)
+##           MY_BRANCH=1      || --branch local
+##       - Better yet: when branch name is known simply pass it:
+##           % make lint-helm BRANCH=alt-branch-name
