unit UPlatformMacOSX;
// Note on directories (by eddie):
// We use subfolders of the application directory on tha mac, because:
// 1. Installation on the mac works as follows: Extract and copy an application
// and if you don't like or need the application anymore you move the folder
// to the trash - and you're done.
// 2. If we would use subfolders of the home directory we would have to spread our
// files to many directories - these directories are defined by Apple, but the
// average user doesn't know them, beacuse he or she doesn't need to know them.
// But for UltraStar the user must at least know the songs directory...
//
// Creating a subfolder directly under the home directory is not acceptable.
