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.
The **entrypoints** module contains functions to find and load entry points.
You can install it from PyPI with ``pip install entrypoints``.
To advertise entry points when distributing a package, see
`entry_points in the Python Packaging User Guide
<https://packaging.python.org/en/latest/distributing.html#entry-points>`_.

entrypoints API
===============
.. module:: entrypoints
High-level API
--------------
.. autofunction:: get_single
.. autofunction:: get_group_named
.. autofunction:: get_group_all
These functions will all use ``sys.path`` by default if you don't specify the
*path* parameter. This is normally what you want, so you shouldn't need to
pass *path*.
EntryPoint objects
------------------
.. autoclass:: EntryPoint
.. attribute:: name
The name identifying this entry point
.. attribute:: module_name
The name of an importable module to which it refers
.. attribute:: object_name
The dotted object name within the module, or *None* if the entry point
refers to a module itself.
.. attribute:: extras
Extra setuptools features related to this entry point as a list, or *None*
.. attribute:: distro
The distribution which advertised this entry point -
a :class:`Distribution` instance or None
.. automethod:: load
.. automethod:: from_string
.. autoclass:: Distribution
.. attribute:: name
The name of this distribution
.. attribute:: version
The version of this distribution, as a string
Exceptions
----------
