-#           Stream-lined code of update process.
+#           Stream-lined code of update process: massive refactoring.
+#           Added functionality: If WAIT button is not active, then an existing
+#           customer repository will be repaired, or a not existing repository
+#           will be cloned. The process stops then.
+#           However, if the WAIT button is active, the at least the commands in
+#           opkg_commands will be executed. Changed files in the customer
+#           repository will be worked on: tariff-files will be synced with the
+#           local filesystem, json-files will be downloaded to firmware.
+#           The device-controller firmware will be handled in a later version.
+
+# PLANNED TODOS:
+#   1:  Das Repository wird repariert bwz. neu geklont. Unabhaengig vom WAIT.
+#   2:  Wenn der WAIT-Button aktiv ist, dann wird ein Repository repariert (neu
+#       geklont), aber zusaetzlich werden alle verfuegbaren Dateien als neu
+#       angesehen und die entsprechenden Aktionen durchgefuehrt: tariff-files
+#       spiegeln, json-files laden und dc laden. Also VORSICHT: das repository
+#       muss in diesem fall wirklich in ordnung sein.
+#   3:  Wurde keine Datei geaendert, kein initiales Clone und der WAIT-button
+#       nicht aktiv, so (passiert natuerlich nichts) kann man davon ausgehen,
+#       dass es sich um ein automatisches Update handelt. Dann koennte man im
+#       ISMAS eine entsprechende Meldung anzeigen als Teil von SEND-LAST-VERSION.
+#       Wenn der WAIT-button aktiv ist, dann werden zumindest die opkg-commands
+#       ausgefuehrt.
+#   4:  rsync: immer alle Dateien soiegeln (bis auf opkg-commands)
+#   5:  Falls das Tool mal abstuerzt, dann einen Signal-Handler (fuer TERM)
+#       installieren, sodass zumnidest SEND-LASt-VERSION mit rausgeht.
+#   6:  rsync: explizites Binary, nicht das in busybox enthaltene.
