This would make testing out modules and script packs much easier. Today if you are developing script packs and modules you end up creating packages and then having to drop them in a place that is in your package sources. You then go and install them in the modules folder.

With this change you could just build the package, and then using scriptcs -install just specify the nupkg directly. it will then copy it into either the local packages folder or the global one (depending on if you use -g) and install all the dependencies.
