Hi, Thank you for your interest, I'll add some comments inline below. It's true that the Analysis Framework documentation may be a bit too basic (and a little bit outdated at that). It should be updated and present a more concrete example, say, using an event request instead of doing nothing.

Hi Marc-André, I think it's a very good idea. I recently had to add a dependency to the tmf project, I added it to the target definition, but had (and still have) no idea where to put that dependency for maven and the build still fails :( Using the target definition seems an easier way and if

Hi Bernd, Thanks for the comments. I think we're getting there. Note that I don't expect (or want) the first patch on the topic to fully respond adequately to every point, but just to be satisfying enough to get the concepts in TMF and start being used by actual analysis. It will improve a
