What is "wine module code" ? I tried grepping the wine source code for cedega and cxoffice but found nothing. Please point me in the good direction.
I think whats meant here is one of the 3 wine flavors installed in the package manager. You don't find any trace of cedega or crossover in wine itself. However, inside crossover you will find a wine binary in crossover_install_dir/bin/wine, which you can use like normal wine to run a .exe in the default bottle in crossover. There are some additional environment variables to configure crossover specific things like the bottle to run the app in. No idea about cedega, but I'd expect it to work simmilarly.
