Arguments:

* `asset`: The target asset name. `[file]` is replaced with the original asset. `[path]` is replaced with the path of the original asset and `[query]` with the query. Defaults to `"[path].gz[query]"`.
* `filename`: A `function(asset)` which receives the asset name (after processing `asset` option) and returns the new asset name. Defaults to `false`.
* `algorithm`: Can be a `function(buf, callback)` or a string. For a string the algorithm is taken from `zlib` (or zopfli for `zopfli`). Defaults to `"gzip"`.
* `test`: All assets matching this RegExp are processed. Defaults to every asset.
* `threshold`: Only assets bigger than this size are processed. In bytes. Defaults to `0`.
