+# Um TrustBridge zu installieren:
+# 1. Prüfen Sie ob Sie dieser Datei genügend vertrauen, um ihr die Kontrolle
+#    über diesen Rechner zu übergeben. Beispielsweise durch Vergleich mit
+#    einer starken Prüfsumme aus einer zweiten, unabhängigen Quelle.
+# 2. Öffnen Sie eine Kommandozeile, z.B. klicken Sie auf das "Terminal"-Symbol.
+# 3. Wechseln Sie in das Verzeichnis, in welchem diese Datei gespeichert ist.
+#    Geben Sie Z.B. in die Kommandozeile ein: cd ~/Schreibtisch
+# 4. Starten Sie die Anwendung auf der Kommandozeile, beispielsweise
+#    als Installation nur für den aktuellen Nutzer, indem Sie eingeben:
+#    	bash TrustBridge-1.0.0-i386.sh
+#    Tipp: Die Tab-Taste nach dem "Tr" ergänzt oft den ganzen Namen.
+#
+# NB: Wir konnten kein übliches .deb Paket verwenden, da wir Ihnen
+# auch die Installation als reiner Nutzer ohne Admin-Rechte ermöglichen.
+#
+# To install TrustBridge:
+# 1. Verify that you trust this specific file far enough, that you are willing
+#    to hand over the control of your computer to it. For example compare
+#    a strong checksum of the file to one from a second, independent source.
+# 2. Open a command line, e.g. click on the "Terminal"-Symbol.
+# 3. Change your working directory to where this file is stored.
+#    For example type "cd ~/Desktop" on your command line.
+# 4. Start the installation on the command line, e.g. for the current user
+#    only by typing something like "bash TrustBridge-1.0.0-i386.sh".
+#    Hint: If you press the tab-key after "Tr" it may complete the filename.
+#
+# N.B. We could not have used a .deb package, because the installation must
+# also work without without adminstrator priviledges.
+#
+#
+# Search the file for 'version()' to find the license information.

-#!/bin/bash
-# Um TrustBridge zu installieren:
-# 1. Prüfen Sie ob Sie dieser Datei genügend vertrauen, um ihr die Kontrolle
-#    über diesen Rechner zu übergeben. Beispielsweise durch Vergleich mit
-#    einer starken Prüfsumme aus einer zweiten, unabhängigen Quelle.
-# 2. Öffnen Sie eine Kommandozeile, z.B. klicken Sie auf das "Terminal"-Symbol.
-# 3. Wechseln Sie in das Verzeichnis, in welchem diese Datei gespeichert ist.
-#    Geben Sie Z.B. in die Kommandozeile ein: cd ~/Schreibtisch
-# 4. Starten Sie die Anwendung auf der Kommandozeile, beispielsweise
-#    als Installation nur für den aktuellen Nutzer, indem Sie eingeben:
-#    	bash TrustBridge-1.0.0-i386.sh
-#    Tipp: Die Tab-Taste nach dem "Tr" ergänzt oft den ganzen Namen.
-#
-# NB: Wir konnten kein übliches .deb Paket verwenden, da wir Ihnen
-# auch die Installation als reiner Nutzer ohne Admin-Rechte ermöglichen.
-#
-# To install TrustBridge:
-# 1. Verify that you trust this specific file far enough, that you are willing
-#    to hand over the control of your computer to it. For example compare
-#    a strong checksum of the file to one from a second, independent source.
-# 2. Open a command line, e.g. click on the "Terminal"-Symbol.
-# 3. Change your working directory to where this file is stored.
-#    For example type "cd ~/Desktop" on your command line.
-# 4. Start the installation on the command line, e.g. for the current user
-#    only by typing something like "bash TrustBridge-1.0.0-i386.sh".
-#    Hint: If you press the tab-key after "Tr" it may complete the filename.
-#
-# N.B. We could not have used a .deb package, because the installation must
-# also work without without adminstrator priviledges.
-#
-#
-# Search the file for 'version()' to find the license information.
