install entry points in a dedicated binary package

[PICCA Frederic-Emmanuel]

Hello,

I am modernizing the binoculars package. I switch it to pyproject.toml and now 
I need to update the packaging.

I would like your advices in order to replace this d/rules

export DH_VERBOSE=1
export PYBUILD_NAME=binoculars
export PYBUILD_AFTER_INSTALL=rm -rf {destdir}/usr/bin/

%:
        dh $@ --with python3,sphinxdoc --buildsystem=pybuild

override_dh_auto_test:
        dh_auto_test -- --system=custom --test-args='{interpreter} -m unittest 
discover -s tests -t {dir} -v'

override_dh_install:
        dh_numpy3
        dh_install

        # install scripts into binoculars                                       
                                                                                
                                                                                
                                       
        python3 setup.py install_scripts -d debian/binoculars/usr/bin

override_dh_sphinxdoc:
ifeq (,$(findstring nodocs, $(DEB_BUILD_OPTIONS)))
        PYTHONPATH=. http_proxy='127.0.0.1:9' sphinx-build -N -bhtml doc/source 
build/html # HTML generator                                                     
                                                                                
                                       
        dh_installdocs -p binoculars-doc "build/html"
        dh_sphinxdoc -O--buildsystem=pybuild
endif

with the something fonctionnaly equivalent which install the entry points only 
in the binoculars package.

replace this combination

export PYBUILD_AFTER_INSTALL=rm -rf {destdir}/usr/bin/

...
# install scripts into binoculars                                               
                                                                                
                                                                                
                               
python3 setup.py install_scripts -d debian/binoculars/usr/bin
