  This instructs the node to move a child of the given directory to a
- different directory, both of which must be mutable. The child can also
- be renamed in the process. The to_dir parameter should contain the name
- of a subdirectory of the dircap from which the child is being moved
- (multiple levels of descent are supported), unless the file is to be
- moved to an unrelated directory. In the latter case, this can be
- specified by passing a target_type=uri argument and the target URI in
- to_dir=. If the target is the name of a subdirectory, this can be
- signified by passing target_type=name. A new name for the child can
- also be specified using the to_name= parameter.
