        Downloads all dependencies defined in `Podfile` and creates an Xcode
        Pods library project in `./Pods`.

        The Xcode project file should be specified in your `Podfile` like this:

            project 'path/to/XcodeProject.xcodeproj'

        If no project is specified, then a search for an Xcode project will
        be made. If more than one Xcode project is found, the command will
        raise an error.

        This will configure the project to reference the Pods static library,
        add a build configuration file, and add a post build script to copy
        Pod resources.
