Wish: documentation and slidedeck in one directory structure

[inktvis75]

It is maybe already possible, but I have no idea how to do it.

What I want is a directory structure like this:

conf.py
...
source/workbook.rst
source/slides.rst
source/workbook/introduction.rst
source/slides.rst/introduction.rst

of course, the content of the introduction.rst is different. If I do a make html or make latexpdf, it should compile workbook.rst and if I execute a make slides, it should create the slide-deck

maybe similar to latex_documents ?
