The project wms2GO is designed to build a local executable WebGIS application out of pre-defined or manual selected WMS (OGC WebMapServices) of free map extract. Thus it is possible to use this application on a mobile device (e.g. a laptop) without any network access.
Manuals for Installation and Setup have been added to the SVN. You can find them here:

At the moment, they are only available in german, but this may change...
