+Start an active filesystem translator that is not attached to any parent
+filesystem node, but rather is accessible only as the root filesystem
+of a new subprocess.
+
+The @var{node} argument is used only to give the underlying node port
+to the translator.  The active translator control port is used only by
+settrans itself to get a root directory port, for which it supplies a
+null @code{..} port.  It then works like @kbd{chroot @var{x}
+@var{command} [@var{args}@dots{}]} where @var{x} is the (nameless)
+root directory of the new active translator.

 Create @var{node} as a zero-length file if it doesn't already exist.
