A successor to SeText and StructuredText, reStructured Text is another approach to ASCII representation of rich formatted text that is meant to be readable. It is intended to solve a similar problem to what TextFormattingRules solves, but has a different lineage. It is used by some versions of Zope, and by the Plone content-editing package, which has a wiki style option now. reST, as it's also known, is also used to document Python source for some projects. MoinMoin supports using reStructuredText as wiki markup.
