No intellectual achievement today is a result of a single person's work. Everything one does is based on work and knowledge and experience of innumerous other people. Moreover, in many cases other people are actively involved, with their ides, suggestions, critic and improvements in a person's work.
This tool is no exception. It is based on the concept by Uwe Oestermeier, who kindly provided his own tool as a sample. Simon Wiest and Clemens Jürgens further extended the tool and brought in some very useful new ideas. The tool was developed at the Department of Computer Architecture, headed by Prof. Andreas Zell, at the University of Tübingen, and the funding was provided mainly by the German state of Baden-Württemberg.
