pyproject build (hatchling) with entry-points

[Gabriel Wicki <gabriel@erlikon.ch>]

Hi there!

I have created a Python application that seems to build just fine (using
a pyproject.toml file and the hatchling build system, by invoking
`python3 -m build`), including script entrypoints and everything.

Unfortunately I am not as lucky with my Guix packaging attempts.  My
Python project creates a wheel and a tar.gz dist file with the
corresponding entry_points.txt file, but the pyproject-build-system's
create-entrypoints phase does not seem to pick it up.  Making the guix
build fail I see that no entry_points.txt makes its way into the build
process.  Am I doing it wrongly?  Am I missing something?  Is this a
known issue?

Thanks for any and all pointers leading me further down the path
