$ npm install --save decompress-tarbz2
```
## Usage
```js
var Decompress = require('decompress');
var tarbz2 = require('decompress-tarbz2');
const decompress = require('decompress');
const decompressTarbz = require('decompress-tarbz2');
var decompress = new Decompress()
.src('foo.tar.bz2')
.dest('dest')
.use(tarbz2({strip: 1}));
decompress.run(function (err, files) {
if (err) {
throw err;
}
console.log('Files extracted successfully!');
decompress('unicorn.tar.gz', 'dist', {
