Hi Jonas,

I understood that I can add/manage aspects at runtime and associate them to
pointcuts. I don't need to reload classes for that, right? Now, what do I
need to do to add pointcuts at runtime without going through the
configuration file? How do you see that could be implemented? I have  been
looking at the definition package, but I must admit I got lost quick ;-) I
need a little help to get me started.

Thanks,
-- Vincent
