Aside:

The essence of coolness: Bruce Eckel’s [_Python 3 Patterns & Idioms_][book] is available as a fork-able [repo on Bitbucket][repo].

I am already pretty well committed to using [Scrivener][] for the current book, but maybe the next book will use some infrastructure like this. (Assuming publishers will allow such things.)
