Extract all streams

*Imported Issue from a former Bitbucket user*

Hi, is it possible to add extraction of all streams ($name.stream) when run? maybe with an optional argument to use it thanks

Start by locating the command entry point and the existing extraction path used when the tool is run. Clarify how stream names are discovered and how an optional argument should select all $name.stream files; done means the behavior is specified and covered for both default and opt-in runs.
