+#!/usr/bin/env python3
+#
+# for python3.5 or higher
+#-----------------------------------
+# Within Marlin project MarlinFirmware/Configurations, this program visits all folders
+# under .../config/examples/*, processing each Configuration.h, Configuration_adv.h,
+# _Bootscreen.h, and _Statusscreen.h, to insert:
+#    #define CONFIG_EXAMPLES_DIR "examples/<style>/<vendor>/<model>"
+# ... or similar path leading to this file.
+#
+# Warning: The program modifies files in place, so be sure to back them up first if needed.
+# Can be run multiple times if needed. Only modifies files which don't have
+# correct #define CONFIG_EXAMPLES_DIR line.
+#
+# Invocation:
+#-------------
+# 1. Change directory to your MarlinFirmware/Configurations working copy
+# 2. python3 config-labels.py
+#
+#-----------------------------------
+# 2020-05-10 GMW original
+# 2020-06-05 SRL style tweaks
