TODO. In the meantime, you can just run dir within the iam directory and probably find your way around.
Remember that you can often cd into objects to find more related objects within. The hierarchy looks like this:
-- iam
|-- policies
|-- my-policy # Policy name
|-- roles
|-- my-role # Role name
|-- policies
|-- my-embedded-policy #name of an embedded policy
|-- my-attached-policy #name of an attached policy
|-- statements
|-- my-policy-statement-sid #sid of a statement within one of the policies associated with the role
