The source map options for the grunt-contrib suite.

Type: boolean
Default: false

Set to true to create a source map. The source map will be created alongside the destination file, and share the same file name with the .map extension appended to it.

Type: string function
Default: undefined

To customize the name or location of the generated source map, pass a string to indicate where to write the source map to. If a function is provided, the uglify destination is passed as the argument and the return value will be used as the file name.

Should this be split out into sourceMapName and sourceMapDir options?

Type: string
Default: "Embed"

Determines the type of source map that is generated. The default value, embed, places the content of the sources directly into the map. link will reference the original sources in the map as links. inline will store the entire map as a data URI in the destination file.
