== Docstrings ==
* Python provides a docstrings to document classes and functions. If the class is a class used by others (such as the
RelLib classes), the docstrings should follow the [http://epydoc.sourceforge.net/manual-epytext.html epydoc] format. This allows us to extract [http://www.gramps-project.org/docs/ API] documentation. Classes that are not core reusable classes do not have to follow this format, but should be documented using docstrings.
