We mention them in the Extending & Embedding guide, and link out to
the page on packaging.python.org that describes them in more detail:
https://docs.python.org/3/extending/index.html#recommended-third-party-tools

Cheers,
Nick.

P.S. There are also a number of open issues at
https://github.com/pypa/python-packaging-user-guide/issues regarding
additional projects that should be mentioned in
