where positional can be:

Address syntax can be:

    - `protocol://user@address:port:wrkdir` for protocols such as Sftp, Scp, Ftp
    - `s3://bucket-name@region:profile:/wrkdir` for Aws S3 protocol
    - `\\\\<server>[:port]\\<share>[\\path]` for SMB (on Windows)
    - `smb://[user@]<server>[:port]</share>[/path]` for SMB (on other systems)
