+==== Textual descriptions for the libraries ====
+The libmvw.so should contain classes for the connection and query
+to the database.
+So that each application can individual access the database and it should be easy to design one commandline version and one GUI version.
+The Scripts in the database should extend every function of the library. (prehook_class_function, posthook_class_function)
+All details should be hidden between an Interface class, which
+ should be the only one accessible from the application.
+(NO direct connection to the database, except: the user has the
+right for that (admin_db)).
