Thanks. Feature-wish: Write an extension manual.

How? The extensions can be installed and used even without any
paymentlib extension. The version of the paymentlib can only be
suggested. In tt_products 2.6.0 there will be also a version check for
the Payment Library, but inside of the code. If the installed version
number of the Payment Library is too low, nothing will happen. Or maybe
an error message should be displayed. Other installed extension might
rely on a lower version of the Payment Library.
