+# This script is executed at the start and end of each run-level
+# transition.  It is the first 'stop' script and the last 'start'
+# script.
+#
+# 'stop'  sets the correct colour power LED to flash between the
+#         two colours of the previous and next runlevel.
+# 'start' sets the LED to steady
+#
+# 'red'   is the initial setting on kernel boot
+#
+# 'amber' is used for run levels S (from /linuxrc), 0 (halt),
+#         1 (single user) and 6 (reboot).  halt and reboot do not
+#         terminate therefore the LED remains flashing until the
+#         kernel terminates.
+#
+# 'green' is used for run levels 2-5 - the normal user run levels.
+#
+# colours are 'g' (green), 'r' (red) or 'gr' (amber).
