This is a shim of ns-package-graph that makes it work against the local package directory.
By no means do I intend to take credit, I just hijacked the package and dynamically modify it for my own use.
npm install -g https://github.com/remy/package-graph.git
package-graph [options]
The difference between this and the original ns-package-graph is (obviously) it's running from your locally installed packages, but it shows you the logical tree, not the tree from disk (though this is simple to add at some point).
I've only tested basic support for this, and I'm not totally sure that tweaking the --child and --group options works or not.
Pretty simple. I include the ns-package-graph as a dependency, but instead of using require, I used proxyquire and I intercept the nsolid-cli load.
I return my own object with a run method that walks the local dependencies and then massages the data into the format that the ns-package-graph wants.
