The latest version of MCREPOGEN was released, including multiple bug fixes, tools for analyzing the structure of existing repositories and improved documentation. A summary of the newest features follows:

- Create and document tools for analyzing existing repositories. An example
  of analyzing the Bazaar project is included.

- Use Sphinx for the documentation. With sphinx installed, type ``make html``
  in the ``doc/`` directory to build HTML versions of the documentation.

- Add a ``--show-config`` feature that prints the complete configuration used,
  including all default parameter values, without doing any simulation

- Fix a bug with non-existent configuration files, or those that are missing
  sections.

- Stop using setuptools for distribution as it is unnecessary

- Add more tests
