This Site is created with a rubyscript. The source is a file directory with HTML-Documents. This directory structure and the meta-tags in the HTML files are used to create the web site with its navigation.
The structure of the site can be influeneced by control files, path and file names. There is no detailed user documentation about the programm. Please check the german documentation ;-) or the API-documentation.
It is possible to adapt the programm. So I made a version for the VCD Baden-Württemberg (an ecologic orientated club for traffic affairs). To make it easy for other VCD-webmasters, I "compiled" the programm with rubyscript2exe and wrote a VCD-specific documentation.
