|

* Decompress `data` with inflate/ungzip and `options`. Autodetect

* format via wrapper header by default. That's why we don't provide

* - windowBits
|

*
|

* [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)

* for more information.
|

*
|

* Sugar (options):
|

*
|
||||
* - `raw` (Boolean) - say that we work with raw stream, if you don't wish to specify

* negative windowBits implicitly.
|

* - `to` (String) - if equal to 'string', then result will be converted

|

* chunk length can differ from `chunkSize`, depending on content.
