+      This package provides an API for querying the distutils metadata
+      written in the PKG-INFO file inside a source distriubtion (an sdist)
+      or a binary distribution (e.g., created by running bdist_egg). It can
+      also query the EGG-INFO directory of an installed distribution, and the
+      *.egg-info stored in a “development checkout” (e.g, created by running
+      setup.py develop).
