* `Env.MultiMap` returns the contents of an Env as `map[string][]string` * `Env.InitMultiMap` initializes the contents of an Env from a `map[string][]string` This makes it easier to import and export an Env to other formats (specifically `beam/data` messages) Docker-DCO-1.1-Signed-off-by: Solomon Hykes <solomon@docker.com> (github: shykes)
