Type: stream

If supplied, the new instance will automatically be piped to this stream.

Low Level API

A low-level non-stream based API is available. It has only two methods.

`js
var createTracker = require('last-line-stream/tracker');
var tracker = createTracker();

// append some text.
tracker.update(someString);

// Find the complete last line of all the text appended.
tracker.lastLine();
``
