		Pass `false` to skip mangling names.

		- `output`

		Pass an object if you wish to specify additional [output
		options](http://lisperator.net/uglifyjs/codegen). The defaults are
		optimized for best compression.

		- `compress`

		Pass an object to specify custom [compressor
		options](http://lisperator.net/uglifyjs/compress). Pass `false` to skip
		compression completely.

		- `preserveComments`

		A convenience option for `options.output.comments`. Defaults to preserving no
		comments.

		- `all`

		Preserve all comments in code blocks

		- `some`

		Preserve comments that start with a bang (`!`) or include a Closure
		Compiler directive (`@preserve`, `@license`, `@cc_on`)

		- `function`

		Specify your own comment preservation function. You will be passed the
		current node and the current comment and are expected to return either
		`true` or `false`.

		You can also pass the `uglify` function any of the options [listed
		here](https://github.com/mishoo/UglifyJS2#the-simple-way) to modify
		UglifyJS's behavior.


		### Source Maps

		You can have UglifyJS’s generated source maps emitted on the stream by passing
		`true` for the `outSourceMap` option. The file object’s path will be based on
		the input file’s, with ‘.map’ appended.

		Input source maps are no supported by this plugin at this time.
