GUI for launching grids. Early version, but should work fine.
Will execute all OpenSim services redirect their input/output/errors to the selected "GUI module". This version has following "GUI modules": * Windows Forms * Windows Service (doesn't work yet) * Console * TCP daemon This means that OpenSim can now run in a single console for those who want that. Console functionallity is not too rich yet, but code/framework is there... more to come. :)
