+# Some notes:
+#   -The switch processing/argument handling is very basic.
+#   -This script assumes session names start with "Session" when listing
+#    sessions. This is settable via a variable.
+#
+# Possible actions:
+#   -h : Show help screen
+#   -l : List current consolekit sessions
+#   -u : Unlock specified session (one parameter required - the session name)
+#   -a : Attempt to unlock all sessions
+
+# Return code documentation
+#
+#  0: Script executed normally
+#  1: Root access is not present for script
+#  2: No arguments passed
+#  3: Multiple actions requested, can only do one at a time
+#  4: Argument passed was not recognized
+#  5: Multiple arguments passed for unlock single session, only one needed
+#  6: The argument required for unlocksession() is missing (internal error)
