I probably wasn't explicit enough. At the core of this function is a Python script that calls python-ly (which can be installed through pip). What I'm thinking about is integrating this script in the doc build process, which should definitely be worth the effort and "cost" IMO. > >> But I'm stuck with the problem of getting to the highlighted HTML out of >> the function and back into the book.

I'll comment on that as soon as I have something to show.
