Where can I find these too. I would like to avoid any classes that are compiler
specific. We want to be as portable as possible.

That is the aim. We can probably use a lot of the code from the Whisper
framework to get a lot our back end functions for Windows and Mac. Uli you made
at one stage some classes for the high level API if I remember correctly. Are
you still working on this? If so I would like to review it.

Yay more Australians helping with OpenCard =).
As soon as I can afford to buy VirtualPC I would like to contribute some PC
code. Then we can test it with CodeWarrior and Visual C++ on Windows.
Dylan, do you have a Mac? It would be good if you could look at the mac
executables so we can make sure everything is working the same.
