Hi Wolf,
Well I managed to sort it out last weekend.
I have added a --docker-entry-point option which can be invoked
multiple times to provide the docker EntryPoint value in exec form.
I have left the --entry-point behaviour alone except the
--docker-entry-point takes precedence.
I still have the docs to update, and to test the some of the different
cases, but it all seems to work.
Thanks again,
Graham
