Hi,
This is a very simple patch which will allow Tasks to determine the
version of Ant they are being run in.
This is especially useful for knowing which methods on Project are
available.
e.g.
public void log(String message, Throwable throwable, int
msgLevel) et al
are only available @since 1.7.
Cheers,
Nick Pellow
