+#           too small when updating apism.
+#           Fix display of UPDATE_SUCCESS when opkg_command fails. Detected when
+#           updating apsim failed.
+# 1.3.11:   Integrate version of ATBUpdateTool in SendLastVersion-ISMAS-message.
+# 1.3.12:   Add command parameters for output of yocto-infos about ATBUpdateTool.
+#           Use 'git pull' instead of 'git fetch'.
+#           Use 'git clone --filter=blob:none' instead of 'git clone' to speed
+#           up cloning of customer repository.
+# 1.3.13:   Fix: if the customer repository is corrupted, remove it and re-clone
+#           the repository (without checking the ISMAS-trigger (WAIT-)button.
+# 1.3.14:   Add additional check for sanity of customer repository using
+#           "git fsck".
+#           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.
+# 1.3.15:   Bug fixes found during testing.
+#           Do not disable Exit-button during update-process.
+#           Removed worker-thread with an own event-loop: only the GUI thread
+#           has an event loop. Tested JSON-downloads several times successfully
+#           (using the slave lib where the CA helper tool was active as master).
+#           Turned previous worker-object into its own thread, but without any
+#           own event-loop (so it cannot block anything inside the CA-plugin).
+# 1.3.16:   Bug fixes found during testing.
+# 1.3.17:   Add ATBUpdateTool.ini and custom command line parser. Settings
+#           given in ATBUpdateTool.ini can be overwritten on the command-line.
+# 1.3.18:   Bug fixes found during testing.
+# 1.3.19:   Bug fixes found during testing.
+# 1.3.20:   Bug fixes found during testing.
+# 1.3.21:   Bug fixes found during testing:
+#           Fix directory of ATBUpdateTool.ini to be the working directory of
+#           the application rather than just ".".
+#           Check existance of etc-directory inside customer repository.
+#           Check for valid ISMAS trigger (button) 15x (=90s).
+#           NOTE: if the customer repository is cloned (or repaired and cloned
+#           again), and if the settings always-download-config=true and
+#           always-download-dc=true in the ATBUpdateTool.ini file, the download
+#           the printer-json files and the device controller file, even without
+#           an activated ISMAS trigger (button). The tariff-files are rsynced to
+#           the local filesystem for such clone.
+#           Set new filename for device controller: dc2c.bin.
+# 1.3.22:   Bug fixes found during testing:
+#           Fix the path-names of the json-files and the device-controller.
+#           Set automatic download of json-file in ATBUpdateTool.ini file for
+#           a fresh clone of the repository.
+# 1.3.23:   Added a 'break' to prevent a possible endless loop when checking if
+#           the device is alive.
+#
+# NOTE:     The versioning info has to be shifted up by one version, i.e. what
+#           happened for 1.3.23 was actually done in 1.3.24.
+# 1.3.24
+#
+# 1.3._24_: Special version for szeged using a old dc-controller (4.42):
+#           Changes:
+#               (1) the ini-File now uses the libCAmaster.so.
+# 1.3._25_: Again special version for szeged, using interface.h, version 4.4.
+# 1.4.0   : Start with version at 1.4.0 (mainly to see a difference with Szeged)
+#           Set hash-value in EVENT-objects. Set location (project), version
+#           and info in send-last-version.
+#           If the customer repository does not exist, then do not check the
+#           ISMAS trigger, but proceed with the update procedure. Otherwise,
+#           check the ISMAS update-trigger as first step.
+#           If the current time is between 0.00 - 4.00 o'clock, then a wrong
+#           trigger-value will result in an UPDATE_STEP_NOT_NECESSARY.
+#           Move final processing to subclass UpdateProcessRunning.
+#           Disable EXIT-button for the whole update-process, except for the
+#           checking of the ISMAS-trigger-button (aka WAIT-button).
+# 1.4.1   : Sync files in the customer repository (under ./etc) as the very
+#           first step
+# 1.4.2   : Do not check if <repo_dir>/etc/psa_tariff and /etc/psa_tariff are
+#           the same after an rsync. They might be noy after a change of the
+#           customer-number.
+# 1.4.3   : Use global directory for device-controller interfaces.h-file.
+# 1.4.4   : Add additional debug messages when downloading json-files.
+#           Move rsyncing of the customer-repository after the actual fetching
+#           of the repository. Otherwise, the update of, for instance
+#           tariff-files, would always be a step behind.
+# 1.4.5   : In case a new branch has been created in a remote
+#           customer-repository (e.g. origin/zg1/zone101), then fetch/pull
+#           this branch before switching to this now locally existen branch.
+#         : Improve output of GUI/Console and messages sent to ISMAS.
+#         : Fix: do not send the json-files to dc in any case. Bug introduced
+#           when pulling new branch, but branch already existed locally.
+# 1.4.6   : No exit()-call if loading CA-plugin fails.
+#           Check m_hw (pointer to CA-(Slave)Plugin) before its use.
+#           Only exit() if firmware is configured to be possibly updated, but
+#           loading the CA-plugin failed.
+VERSION="1.4.7"
+# 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.
+#   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.
+#   7:  Versionen der Json-Files lassen sich auslesen.
+#       Problem: Einstellungen in den Json-Files lassen sich auch mittels
+#       Funktionen in der CD-Library ueberschreiben. Damit ist dann wieder nicht
+#       mehr so klar, was jetzt eigentlich aktiv ist.
+#   8:  m_alwaysDownloadConfig und m_alwaysDownloadDC: vorbereitet: man koennte
+#       es so arrangieren, dass der DC plus die Json-files im Repository immer
+#       runtergeladen werden, obwohl sich im Repository gar nicts veraendert
+#       hat. Eeventuell nuetzlich beim initialen Setuo eines PSA.
+#   9:  Das Kunden-Repository sollte immer gezogen werden, unabhaengig von der
+#       Stellung des WAIT-Button. Grund: es koennte sein, dass andernfalls ein
+#       PSA weit hiter anderen steht, und dann ploetzlich einmal alle vorher-
+#       gehenden Aenderungen anzieht, die gar nicht fuer ihn gemeint waren.
+#  11:  Das Edit-Fenster teilen um die Anzeige zu verbessern.
+#  12:  Bei einem Update muss immer ersichtlich sein, warum es ueberhaupt
+#       angestossen wurde. Steht kein "WAIT" im ISMAS-Trigger, dann kann man
+#       davon ausgehen, dass es sich um ein automatisches Update handelt.
+#       In jedem Fall wird bei einem automatischen Update, bei dem der WAIT-
+#       Button nicht gesetzt war, ein "OK" gesendet, falls sonst nichts weiter
+#       zu tun ist. Beachte aber: wir haben auch noch den Fall, dass eine SD-
+#       Karte gesteckt wird. In diesem Fall wird ein komplettes Update gefahren,
+#       und zwar explizit auch ohne WAIT-Button.
+#       Am Ende eines Updates steht im ISMAS entweder ein "OK" oder ein "FAIL".
+# 13:   SendLastVersion: fuer jedes erfolgreich installierte Paket eine
+#       Send-Last-Version-Nachricht an ISMAS. Dadurch entsteht im ISMAS eine
+#       History (Christian darueber informieren).
+# 14:   Installiert werden nur Dateien, die neu sind oder geaendert wurden.
+#       Nicht etwas Dateien, die geloescht wurden: sicherstellen, dass man hier
+#       immer direkt im repository arbeitet, nicht auf dem Filesystem.
+#       Ferner: der DeviceController heisst dc2c.bin, auch fuer die Jsons
+#       sind Dtandard-Namen vergeben. Alternativ: alle vorhandenen Jsons
+#       werden runtergeladen: Thomas ist eh fuer deren Inhalte verantworlich.
+#       WICHTIG: immer ueberpruefen, ob die Dateien im Customer-Repository
+#       wirklich die richtigen Dateien sind.
+# 15:   Der WAIT-Button laesst sich auf WAIT zuruecksetzen (etwa wenn git
+#       selber Probleme hatte).
+# 16:   Der Download-Thread sollte sowohl die auto-Variable auf false setzen
+#       als auch den cycle-Timer stoppen, damit sichergestellt ist, dass der
+#       Download des DC nicht gestoert wird.
