Wikir converts reStructuredText documents to various Wiki formats. Currently, Google Code Wiki Syntax is the target, but compatibility with Moin Moin Wiki Syntax and Trac Wiki Syntax is maintained when possible.

How to create quick, good-looking presentation slide shows with Docutils [1]/reStructuredText [2] and S5 [3]. This document serves both as a user manual and as a usage example of the s5_html.py writer and the rst2s5.py front end.

Create your document in plain text -- a format that can be read and written anywhere, anytime, on any computer. Organize your thoughts by what they mean, not how they look on the page. Your writing tool shouldn't distract you with a laundry list of choices that have nothing to do with meaning. Style your work in a way that flows naturally from the organization of your ideas. You've composed naturally without the distraction of styling, now let the styling follow naturally from your composition. Share your work - in plain text that can be read and edited anywhere, in HTML, the universal language of the web, or in PDF, a format created for documents you want to print out and hold in your hands.
