A Quieter NSLog

void QuietLog (NSString *format, ...)
{
    // get a reference to the arguments on the stack that follow
    // the format paramter
    va_list argList;
    va_start (argList, format);
    // NSString luckily provides us with this handy method which
    // will do all the work for us, including %@
    NSString *string;
    string = [[NSString alloc] initWithFormat: format
                              arguments: argList];
    va_end  (argList);
    // send it to standard out.
    printf ("%s\n", [string UTF8String]);
    [string release];
} // QuietLog
