I understand better how difficult a task you have set yourself!

(But I worry that comparing with 'expected' output is combining/confusing testing with documentation?)

Is/could it be possible to change the syntax coloring with change to a (possibly external) CSS files?

A jamfile to run all of these examples would still be really good.


PS I'd also point out that one could add the examples to Doxygen-syntax comments.
For anyone starting on documenting a new library, this might be easier? But you didn't start from there...
