I don't think I'll ever be able to turn new features in a software as complex as yours that fast. I'm trying to compile Argyll 0.60 using the Microsoft Visual C++ Express. I'm trying to understand the various dependencies in your source and my c is very rusted. But I'm in no rush. This is fun. I looked at Jam. The thing is I'd like to step through your code, once compiled, to execute it for my own understanding but I don't think that can be done with Jam? Roger Breton
