It would be very handy to have an option to generate a list of the included packages into a suitably named text file and their licence files (usually Licen[sc]e.txt in the top directory of the package) - Possibly by producing a single text file with each package name, (ideally with the URL as well), as a header followed by the content of the respective licence file. It might be nice if the header included the version used as well, possibly optionally.
