Kludget Package

The most basic Kludget package is a ZIP archive that contains just two files. An HTML file and a configuration file (kludget.xml).

A widget package may also contain a menu.xml file that defines its context menu. And a preference.xml file that defines options for the preference window.

That package may also of course, contain widget resources such as images, css, javascript, xml.
