		## Transform Stream Usage

		Like the `crypto.Hash` class, `adler32.Hash` extends the `stream.Transform` class. You can use the stream `.write()` and
		`.read()` methods in place of the deprecated `.update()` and `.digest()` methods. See the
		[Node.js stream module](http://nodejs.org/api/stream.html) documentation for more information about streaming.
		`.read()` methods in place of the legacy `.update()` and `.digest()` methods.

		var hash = new adler32.Hash({
		encoding: 'hex' // Sets the type of data returned by the read() method. Defaults to 'buffer'.
		});

		// Write data to the stream in multiple chunks.
		hash.write('foo');
		hash.write('bar');

		// This is important! No data will be available for reading until end() is called.
		hash.end();

		// Read should return a hexidecimal formatted string due to the encoding option being set to 'hex'.
		var hex_digest = hash.read();

		See the [Node.js stream module](http://nodejs.org/api/stream.html) documentation for more information about streaming.
