This needs both better documentation and (for #3) a better wrapper around the aws S3 cp command. Notable issues:

1) It's super unclear what path you start in, to know how to grab the source

2) there's no documentation around targeting source file(s) (i.e. which methods of globbing are supported? shell with question-marks? apache-style *?, etc)

3.) the target destination - you're unable to rewrite the path - it seems to always take the full existing path of the source and try to append it onto the target

Request is to expose all of the functionality of the S3 cp command in the plugin, and to better document the plugin.
