The Atropa TextAnalyzer is a subproject of the Atropa Toolbox.
Tested on Firefox, Chrome, and Internet Explorer. It just works!
Full documentation is available in the source code or in somewhat organized HTML here. There is also a code analysis report if you are into that kind of thing.
Using Visual Studio or WebMatrix? Intellisense support is available from docs/vsdoc/OpenLayersAll.js. Other editors and IDE's may be able to use the javadoc style comments in the source code.
