+# DISCLAIMER
+# ----------
+# Author: Sihao Liu
+#
+# This is a status line script for the CLI tool that happens to include
+# an RLCR status field tied to the Humanize plugin. It is included in
+# this repository solely for community sharing purposes.
+#
+# Provided AS-IS -- it serves as a reference and template only.
+# Only the final field (RLCR) is related to this repository; the rest
+# is generic session information. Future updates to the Humanize plugin
+# will generally not involve changes to this script.
