+PyScaffold is a project generator for bootstrapping Python packages,
+ready to be shared on PyPI and installable via :ref:`pip`.
+It relies on a set of sane default configurations for established tools
+(such as :ref:`setuptools`, pytest_ and Sphinx_) to provide a productive
+environment so developers can start coding right away.
+PyScaffold can also be used with existing projects to make packaging
+easier.
