Before making any changes to the program, please read the file Copyright in the dgd directory. I will not allow any code copyrighted by others to be part of DGD proper, and I reserve the right to modify any patches and bugfixes sent to me, to make them suit my particular style of indentation, variable and function naming, and commenting. I will definitely remove all comments of the form /* bar-bug fixed by foo */. If you don't like this, it suits me fine if you limit it to a bugreport, rather than a bugfix. People who want to make serious additions to the driver (for instance, networking kfuns) should write a separate package. If I like your package, I may decide to support it, and distribute it together with DGD. Such packages should ALWAYS have their own copyright.
