Thanks, that's really helpful. For Visual Studio, can I get away with installing the Express Version or even just Visual C++ 2008 if its just being used as a compiler? Or does it draw on the .NET framework or parts of Visual Studio other than the compiler itself in order to make Sage work with Windows? What are the other Windows development tools needed . . . just Python 2.6 or 7zip & G95 that are listed in the Sage for Windows Wiki? My concern with licensing was that somehow some code from Visual Studio would get used in Sage and my programs would use Sage's code and then if I wanted to do anything remotely commercial I would have to pay $1000 license for Visual Studio. But I think its more like Visual Studio enables the open source Sage code to get along with the Windows environment. Another question about getting rid of Visual Studio once Sage is installed . . . once Visual Studio is gone, will I still be able to install extra packages to Sage? Won't extra packages be Python code that will get installed through Sage's iPython shell? What if there are extra packages that are in c or c++ . . . once Sage is installed will it handle the compilation of c or c++ code like it does the Pyhton code?
