-tox plugins
-===========
-
-.. versionadded:: 2.0
-
-With tox-2.0 a few aspects of tox running can be experimentally modified
-by writing hook functions.  We expect the list of hook function to grow
-over time.
-
-writing a setuptools entrypoints plugin
----------------------------------------
-
-If you have a ``tox_MYPLUGIN.py`` module you could use the following
-rough ``setup.py`` to make it into a package which you can upload to the
-Python packaging index::
-
-    # content of setup.py
-    from setuptools import setup
-
-    if __name__ == "__main__":
-        setup(
-            name='tox-MYPLUGIN',
-            description='tox plugin decsription',
-            license="MIT license",
-            version='0.1',
-            py_modules=['tox_MYPLUGIN'],
-            entry_points={'tox': ['MYPLUGIN = tox_MYPLUGIN']},
-            install_requires=['tox>=2.0'],
-        )
-
-You can then install the plugin to develop it via::
-
-    pip install -e .
-
-and later publish it.
-
-The ``entry_points`` part allows tox to see your plugin during startup.
-
-
-Writing hook implementations
-----------------------------
-
-A plugin module needs can define one or more hook implementation functions::
-
-    from tox import hookimpl
-
-    @hookimpl
-    def tox_addoption(parser):
-        # add your own command line options
-
-
-    @hookimpl
-    def tox_configure(config):
-        # post process tox configuration after cmdline/ini file have
-        # been parsed
-
-If you put this into a module and make it pypi-installable with the ``tox``
-entry point you'll get your code executed as part of a tox run.
-
-
-
-tox hook specifications
-----------------------------
-
-.. automodule:: tox.hookspecs
