[NTG-context] framed with titles

Hi, I'm trying to generate a frame with a title. My first idea is something like (ASCII Art): +- Title -------------+ | Text text text text | | more and more text | +----------------------+ A frame with title breaking the top line . But I am not picky and something like beamer floating boxes (theorem, proof, ...) for latex is good for me too. In wiki, the frames doesn't have title and I'm not sure about if I have to fight with overlays, with MP and this is out of my league. Questions: * what is the way for implement a title in the frame? * Could you write a minimal example witch allows me to complete it for my needs? Thanks. Javier M. Mora
