Internal Program Version: entrypoints  0.3

Entry points are a way for Python packages to advertise objects with
some common interface. The most common examples are console_scripts
entry points, which define shell commands by identifying a Python
function to run.

Groups of entry points, such as console_scripts, point to objects with
similar interfaces. An application might use a group to find its
plugins, or multiple groups if it has different kinds of plugins.
