Cleaning build directory in setup.py

build, distutils, python

Solution

For pre-deletion, just delete it with `distutils.dir_util.remove_tree` before calling setup.

For post-delete, I assume you only want to post-delete after selected commands. Subclass the respective command, override its run method (to invoke remove_tree after calling the base run), and pass the new command into the cmdclass dictionary of setup.
