Compound pathnames have been introduced for navigation, and command execution, in subordinate arks and other contexts.

In the top-level ark you a sub-ark, ark1.

Now you can enter that ark using the pathname /ark1//

This applies recursively. So if in ark1 you create ark1.1, then you can enter it with the pathname /ark1//ark1.1//

Once you have entered an ark, all the commands are processed in that ark. This includes help, which lists only the commands available in the ark you have entered.
