matrix.py is a little launcher tool that knows about the GridInfo
protocol. it expects the grid coordinates to be passed as a commandline argument either as a "matrix:" or as an "opensim:" style URI: matrix://osgrid.org:8002/ you can also provide region/X/Y/Z: matrix://osgrid.org:8002/Wright%20Plaza/128/50/75 and it also understands avatar names and passwords: matrix://mr%20smart:secretpassword@osgrid.org:8002/Wright%20Plaza/128/50/75 when you run it the first time, it will complain about a missing .matrixcfg file --- this is needed so that it can remember where your secondlife client lives on your box. to generate that file, simply run matrix.py --secondlife path-to-your-secondlife-client-executable
