File `build.py` in project root interferes with PEP517 frontends

[reneeotten]

The presence of a file called build.py causes issues for downstream packagers (in this case MacPorts). The documented way to generate a .whl is python -m build; that doesn't work as the local file takes precedence over the module. Can this be resolved, for example, by renaming the file? Thanks!

See: https://github.com/macports/macports-ports/pull/29395/ and https://trac.macports.org/ticket/64425 (different Python package, same problem).
