Just added a VC++ project that uses the SolarSim library. The MultipleRun project can be accessed via anonymous CVS. It includes configuration files for running the World Solar Challenge route.
Finally, I have got around to adding some source code for solar vehicle simulation. The library will build to a set of dlls that can be used for simulation of a race.
Unfortunately I've still got to move some example code into the project before you can really see how to use it.
I have used Doxygen to add documentation to all the source code, so if you are interested you can have a look at the code.
I will try and release a build of the libraries soon...
