Looking at the basic functionality:

<<...>>= starts a code block. Further uses of it will just append. No
delimiter for end (it ends when you start another code/doc block). 

It can be referenced using <<...>> (without the = symbol). The location
of the reference is not relevant. 

So by default, no overwriting or ordering. 

However, noweb is extensible, and Achim linked to the syntax one can use
to extend it. I haven't read those details. 

Hope that helps.
