    // Photoshop Script to Create iPhone Icons from iTunesArtwork
    //
    // WARNING!!! In the rare case that there are name collisions, this script will
    // overwrite (delete perminently) files in the same folder in which the selected
    // iTunesArtwork file is located. Therefore, to be safe, before running the
    // script, it's best to make sure the selected iTuensArtwork file is the only
    // file in its containing folder.

    //
    // Install - Save Create Icons.jsx to:
