{
int processIdentifier = [[NSProcessInfo processInfo] processIdentifier];
NSString *myPath = [NSString stringWithFormat:@"%s",
[[[NSBundle mainBundle] executablePath] fileSystemRepresentation]];
[NSTask launchedTaskWithLaunchPath:myPath arguments:[NSArray
arrayWithObject:[NSString stringWithFormat:@"%d",
processIdentifier]]];
[NSApp terminate:self];
}
