Thanks for the hint, I had a look at it but was a bit set back by the 
complexity of most projects.
I'll have another look to see whether I can find a small project where I 
can understand what to do.
Do you think it'll be easier to grasp than the toolbox_skeleton?
Because without tutorial- or beginner-oriented comments, I could not 
understand where to start and what to do to adapt it to my problem...
