Export ONLY Page Types

I am attempting to create a zip file artifact containing all the Page types for a site. I want to do this programatically and am looking to build a utility that uses the Kentico API directly.I see a way to export a site or to export objects using ExportProvider.ExportSite or ExportProvider.ExportObject.If I use ExportSite I am assuming there is a way to setup a SiteExportSettings defining the PageTypes to exportIf I use ExportObject I am guessing that I would need to iterate a list of PageTypes then run ExportObject for each.I am not seeing a PageTypeProvider which would allow me to get the PageTypes.Any help or example code would be greatly appreciated. Thanks Kellyl
