+
+
+Parso is a Python parser that supports error recovery and round-trip parsing.
+
+Parso has been battle-tested by jedi_. It was pulled out of jedi to be useful
+for other projects as well.
+
+Parso is very simplistic. It consists of a small API to parse Python and
+analyse the parsing tree.
+
+
+Ressources
+==========
+
+- `PyPI <https://pypi.python.org/pypi/parso>`_
+- `Docs <https://parso.readthedocs.org/en/latest/>`_
+- Uses `semantic versioning <http://semver.org/>`_
+
+Installation
+============
+
+    pip install parso
+
+
+Testing
+=======
+
+The test suite depends on ``tox`` and ``pytest``::
+
+    pip install tox pytest
+
+To run the tests for all supported Python versions::
+
+    tox
+
+If you want to test only a specific Python version (e.g. Python 2.7), it's as
+easy as ::
+
+    tox -e py27
+
+Tests are also run automatically on `Travis CI
+<https://travis-ci.org/davidhalter/parso/>`_.
