BOUML is a free UML tool box (under development) allowing you to specify and generate code in C++, Java and Idl. BOUML is extensible, and the external tools (named plug-outs) may be developed in C++ or Java, using BOUML for their definition as any other program. The code generators and reverses are ones of the pre-defined plug-outs included in the BOUML distribution. WWW: http://bouml.free.fr/
