pdf vs epub documentaion - duplicating chapters
https://readthedocs.org/projects/mailmanclient/downloads/pdf/latest/ and https://readthedocs.org/projects/mailmanclient/downloads/epub/latest/ contain both 37 pages.
However the pdf variant has a lot of nearly empty pages, but the epub says everything until page 20 (Index with no entries) and then page 21 starts again with NEWS for mailmanclient, followed by empty API reference section adn Developing MailmanClient section, followed again by Example Usage section. So the epub version includes the "Example usage" section twice. Previouls generated epub documentation of mailmanclient had even more pages and generated more sections twice.
