Arduino 0017 now available.

Awesome! Compiler errors in multi-tab sketches and .h files are now correctly reported and located!

Where is a tutorial that shows how to use .h files for #defines and other functions, how to use multi-tab sketches? I couldn't find such info (I might be blind or I'm missing something) besides library tutorial. I do not wish to create libraries for everything... How you guys do it? I mean I want to separate the executional layer from the logic layer, how do I do that?
