API

copy : (from : String, to : String, [filter : Regex | String -> Boolean = () => true]) -> Promise Error Any Recursively copies files and directories from from to to, where only candidate paths for which filter returns true are copied. If filter is a Regex, filter.test will be used as the predicate. If the operation is successful, the Promise will resolve.

copy checks to see if to is or will be a child of from, and will throw an error if so. This prevents a directory from recursively specifying itself as a candidate path.
