> We can make the output of {{-listCachePools}} prettier by doing the same
> kinds of things as {{ls -l}} does. We probably need to find (or write) some
> code to properly line up columns to avoid ragged-looking output. Finally,
> column headers will be necessary here to let people know what they're looking
> at. Ideally, we'd implement a format-string type argument like {{--format=}}
> for ls.
