      git-vendor is a wrapper around git-subtree commands for checking out and updating vendored dependencies.

      By default git-vendor conforms to the pattern used for vendoring golang dependencies:
        * Dependencies are stored under vendor/ directory in the repo.
        * Dependencies are stored under the fully qualified project path.
            e.g. https://github.com/brettlangdon/forge will be stored under vendor/github.com/brettlangdon/forge.
