I respect your point of view. I also know german so I understood what you are talking about. You believe that having a util for everything is wrong. You want focus here is my focus:

I want to make XOOPS as easy as possible for everyone ! And yes this app will not be perfect but I wanna implement many features that are done manually by now.
Answer please to a simple question. How much time spend to apply a hack such as autologin ?
Ok you say a few its quite simple you have one hack only so you dont have to think about it.
Lets say you wanna update xoops, then some hacked files will be overwritten, so you loose your hack.
You should apply it again but with new files downloaded from the developer of the hack.
Then apply it, again a few more minute.
Now think if you have 3 hacks or a php developer who hacked XOOPS to death !!!!
When a patch is released the developer punches its head against the WALL.
But fortunately we have demokracy so you are free to use whatever you wish.

I'd certainly be interested in seeing the finished work. I can see uses for it, and the auto-login hack, as you said, is an interesting example.

an interesting idea, it looks like a powerful tool which will simplify the progress of upgrade and hack. but i dont think its a good idea that insert hack tags into the source code. can we borrow some concepts from version control system?
