The ŤType-o-graphť project has been written as a PHP function aimed to parse simple text and give "Rich HTML" as an output, e.g. add quotes instead of inch sings ('), clue short words using <nobr> tags and so on.
Wiki Text Formatting Engine (WTF Engine) converts simple text into HTML. It will run on any platform using a variety of languages such as PHP, Perl, JavaScript and VB Script. It is intended to be a library used in other software packages.
