+    If you install Python packages via "pypy3 setup.py install", easy_install_pypy3,
+    pip_pypy3, any provided scripts will go into the install-scripts folder above,

+    so you don't overwrite tools from CPython.
+
+    Setuptools has been installed, so easy_install is available.

+        #{scripts_folder}/pip install --upgrade setuptools
