 9 | ## Usage
10 | 
11 | ``` js
12 | var log = require('single-line-stream')
13 | var fs = require('fs')
14 | 
15 | fs.createReadStream('/dev/urandom', {highWaterMark:16, encoding:'hex'})
16 |   .pipe(log())
17 |   .pipe(process.stdout)
18 | ```
19 | 
20 | The above example will print out a random hex string that updates inplace in your
21 | terminal.
