The program needs a Java environment.

C.a.R. free and open source. It is also a Sourceforge project. The main author of the program is Rene Grothmann a mathematician at the University of Eichstätt, Germany. Other projects have been derived from the main source, e.g., CarMetal with a different GUI. English is one of the two main language of C.a.R. But the user interface has been translated into many other languages, and a full documentation is available in German.
