In general, the Debian tooling installs the package and so the upstream 
build system should generate the entry points scripts no matter which 
approach is used.

There are some differences to be aware of:

If the pybuild 'distutils' plugin is used (i.e. with a setup.py 
project), then the entry points will be created at the "install" step 
and should land in debian/*/usr/bin; you may need to move them into the 
right binary package.

If the pybuild 'pyproject' plugin is used (i.e. with a pyproject.toml 
project), then the entry points will be created in the "build" step. 
They will land in the pybuild {home_dir}/scripts directory and be 
available to the "test" target in PATH for any cli tests that are in the 
test suite. They will get copied into debian/*/usr/bin during the 
"install" step and you may need to move them into the right binary package.

The main things that the packager needs to be aware of are:

* the packaging needs to move the entry points scripts into the correct 
binary package; that might be a debian/package.install file or it might 
be a mv in debian/rules.

* make sure there's a tight enough dependency between the package that 
contains the entry points scripts and the package that contains the 
modules; the entry points scripts include exact versioning on the 
upstream version of the module and if the binary packages don't have 
dependencies that enforce that requirement, the entry points script can 
fail at run time for the user. («python3-foo (= ${binary:Version})» 
should be ok for packages that are only arch:all).
