Hi, User installing the SDK need a understandable log if something goes wrong and they may not be familiar with ant. The log is not just for our use IMO.
Not all users would be willing to contact the dev list for help if something goes wrong with the installer (for starter they are unlikely to be signed up it). A useful stat would be to record failed installs in google analytics - so we know what % of people are having issues and possibly do something about it. Thanks, Justin
