search for: vingetes

I'm working on the next release of coxme (ready to start some testing), and have written major chunks of it using noweb -- very similar to Sweave except I'm generating code and documentation for the code rather than vingetes. The question: I have directory with .Rnw objects and a Makefile therein that generates most of the .R files. I don't see any guidance in the documentation on where this should preferably be placed in the package tree. Thanks for any pointers (or opinions) Terry T
