The Java Wikipedia API (Bliki engine) is a parser library for converting Wikipedia/Mediawiki syntax to HTML. It supports wiki tags for bold, italic, headers, nowiki, source, table of contents, tables, lists, categories, footnotes (references), images, syntax highlighting of source code fragments, templates, and template parser functions.
CMME (Content Management Made Easy) is a Web content management system that aims to be easy to use, doesn't have many requirements, and is still reasonably flexible. It doesn't need a database, doesn't have extensive administrative needs, and works more or less like a wiki. New pages can be made on the fly, rather than through an administrative page.
