Wikiup is a parser for text input files with a very simple and minimal set of syntax rules. It produces HTML output.
The advantage of using such kind of parser, rather than writing HTML directly, is that the source file will never lead to logical errors that might prevent it from being viewed. In a wiki system, when a syntax error occurs, the result might not be as expected, but there will always be a result.
Furthermore, a file with simple wiki syntax is much easier to read and modify than a verbose markup version of a document
