Tutorial 1 (Basic Usage of AqBanking)
[Tutorials]

This tutorial simply creates an instance of AqBanking, initializes and deinitializes it.

You must either choose a frontend to be used with AqBanking or create one yourself by implementing the user interface callbacks of AqBanking.

However, for simplicity reasons we use the console frontend CBanking which implements these callbacks for you.

There are other frontends, e.g. G2Banking for GTK2/Gnome, QBanking for QT3 or KDE3 or KBanking for KDE3.
