Sphinx's doctest support is INGENIOUS. If I ever had to write a book
(please, no!) then I would write it all in Sphinx. For example, you
can do this in Sphinx:
I highly recommend that everyone use this approach when publishing
doctested code. It's just way too distracting to read setup/teardown
code when it only exists so that your code can be tested. Example
code is crucial for explaining how things work and it's even more
crucial that it be concise and not contrived.
