man pages not available when installed with pipx

Description

When installed via pipx install bpython, the man pages for bpython are not available (even the .rst files don't seem to be present).

I took a look at pipx's documentation and they linked to (pycowsay) as an example. From what I can tell the only difference is pycowsay has the man pages built and included in the repo, whereas bpython just has the .rst files.
