When it launches, it - looks around for .saver bundles (in the current directory, and then in - the standard directories) and puts up a pair of windows that allow you - to select the saver to run. This is less clicking than running them - through System Preferences. This is the "SaverTester.app" program. - - Second, it can be used to transform any screen saver into a standalone - program. Just put one (and only one) .saver bundle into the app - bundle's Contents/Resources/ directory, and it will load and run that - saver at start-up (without the saver-selection menu or other chrome). - This is how the "Phosphor.app" and "Apple2.app" programs work. - - Third, it is the scaffolding which turns a set of screen savers into - a single iPhone / iPad program. In that case, all of the savers are - linked in to this executable, since iOS does not allow dynamic loading - of bundles that have executable code in them.
