+                shows the contents of the selected Linux control group
+                hierarchy in a tree. If arguments are specified shows
+                all member processes of the specified control groups
+                plus all their subgroups and their members. The
+                control groups may either be specified by their full
+                file paths or are assumed in the systemd control group
+                hierarchy. If no argument is specified and the current
+                working directory is beneath the control group mount
+                point <filename>/cgroup</filename> shows the contents
+                of the control group the working directory refers
+                to. Otherwise the full systemd control group hierarchy
+                is shown.</para>
