+This plugin provides a clean minimal set of command line options that are added to pytest. For
+further control of coverage specify a coverage config file.
+For example if tests are contained within the directory tree being measured the tests may be
+excluded if desired by using a .coveragerc file with the omit option set::
+ py.test --cov-config .coveragerc
+Where the .coveragerc file contains file globs::
+For full details refer to the `coverage config file`_ documentation.
+.. _`coverage config file`: http://nedbatchelder.com/code/coverage/config.html
+Note that this plugin controls some options and setting the option in the config file will have no
+effect. These include specifying source to be measured (source option) and all data file handling
+(data_file and parallel options).
