Mike, thanks for the code. This is just what I need and works well from the command line. However, I'm a bit of a SAGE and linux newbie and I'm unsure about the best way of integrating this with SAGE. I checked the programming guide, but I only have some basic Python experience and have never done anything with C++ before. If it matters, I'm using Ubuntu 8.04 and have SAGE 3.0.2.
