Kupu is a 'document-centric' open source client-side editor for Mozilla, Netscape and Internet Explorer that makes editing a web page similar to editing a Word document. Inspired by Maik Jablonski's Epoz editor, it was written by Paul Everitt, Guido Wesdorp and Philipp von Weitershausen (and several other contributors) to improve the JavaScript code and architecture, pluggability, standards support, support for webservers other than Zope (which was the original target platform for Epoz), configurability and a lot of other issues.
