+* ``setuptools`` is a (largely) drop-in replacement for ``distutils`` first
+  published in 2004. It's most notable addition over the unmodified

+  command to ``distutils``/``setuptools``. This produces a cross platform
+  binary packaging format (called "wheels" or "wheel files" and defined in
+  :pep:`427`) that allows Python libraries, even those including binary
+  extensions, to be installed on a system without needing to be built
+  locally.
