@/*description:
{
It parses an object design (the syntax conforms to \samp{CWML}, an object modelling language
that \CodeWorker\ proposes by default) and generates a class diagram as a \samp{png} picture.
\GraphViz\ is an open source graph drawing software, called here for building the class
diagram. It requires the description of the graph, generated in \samp{classDiagram.txt}
by the script \samp{classDiagramGraphviz.cwt}.\\
This example cannot work without \GraphViz\ installed on the Web server.
Note that one saves the object design in a virtual file (function \samp{createVirtualTemporaryFile()}).
It avoids saving the design of the client in a temporary physical file before parsing it.
