With package-merge you merge multiple files into one package.json file.

package-merge package.a.json package.b.json package.c.json > package.json

On the command line it exits when there is no strategy to merge the values. In the API you can provide custom handling via callback.

package-deps

With package-deps you get the dependencies of all the project files passed in. With the -d option this also includes the devDependencies. On the command line clashing versions will be reported and the last version wins.
