import class in a exported GP app?

[MSandro]

Hi, I am working on a import script for my projects. My attention here is the download and import of classes in favor of a very modular and easily updatable applications. Since an exported app unfortunately does not start a ProjectEditor and Scripter, I came across several problems: The biggest of these is the fact that I do not know how to import a class into an exported project. Is this posible, and if yes, why?
