Add post-clean command to python setup.py

问题

From resources online, I've learned that the following will add a "post-install" hook if included in setup.py:

from  setuptools  import  setup
from  setuptools.command.install  import  install  as  _install
class  install(_install):
     def  run(self):
         _install.run(self)
         # Do something magical
setup(cmdclass={'install': install})

What I'd like to do, though, is create equivalent behavior after a setup.py clean is executed. Specifically, I'd like setup.py clean to remove the .egg-INFO directory created during the execution of setup.py egg_info.
