This SVG image is a modified export of a sketch or diagram created with Gnome Dia.
When changes are neccessary, other sketches or diagrams in the same look are demanded, copy the following source code from the article's source code between <!-- and -->. Paste it to a plain text editor and save file. Open with or drop it into Gnome Dia. (Hint: Dia saves GZippedXML code.) Within the license it would be nice to return your new diagram source code to public.
