Now made obsolete by rst2slide that ships with docutils, py2slide was a short and sweet slide generator based on reST, focusing on slide reuse. This is no longer available, but if you ask me I'll give you a copy. There is no reason not to use docutils instead.
While attending a Computer Architecture course at IC-Unicamp, I decided to create a tool to aid the teacher. After the course was finished I never had the time (or will) to work on it. So it is available for anybody that might have both. Note that this is a weekend's draft implementation.
