`void NSLog(NSString *format,...'
     ) Writes to stderr an error message of the form:

     <EFBFBD> \i time processName processID format\i0 <EFBFBD>. The format argument
     to `NSLog()' is a format string in the style of the standard C
     function `printf()', followed by an arbitrary number of arguments
     that match conversion specifications (such as %s or %d) in the
     format string. (You can pass an object in the list of arguments by
     specifying % in the format string<EFBFBD>this conversion specification
     gets replaced by the string that the object's description method
     returns.)

void
NSLogv(NSString* format, va_list args)
{
  fprintf(stderr, "", );
  vfprintf(stderr, [[NSString stringWithFormat:format
		     arguments:args] cString]);
}
