Phonegap/Cordova provides a command line script to generate a XCode project. We could "wrap" that script to aid in the "getting started" experience.
The script is described in this Getting Started Guide:
http://docs.phonegap.com/en/2.0.0/guide_getting-started_ios_index.md.html#Getting%20Started%20with%20iOS
./create <project_folder_path> <package_name> <project_name> then press "Enter"

Note: the package_name is important later in the development phases - when the end-user wishes to place his app on an actual device.
