 /** Bootstrapping native UNO.
+
+    Bootstrapping requires the existence of many libraries which are contained
+    in an office installation. To find and load these libraries the Windows
+    registry keys HKEY_CURRENT_USER\Software\OpenOffice.org\UNO\InstallPath
+    and HKEY_LOCAL_MACHINE\Software\OpenOffice.org\UNO\InstallPath are examined.
+    These contain the paths to the program folder of the office which was
+    installed most recently. Please note that the office's setup either
+    writes the key in HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE dependent on
+    whether the user chooses a user installation or an installation for all
+    users.
