 Apart from the denotational semantics our contract language is also
-equipped with a reduction semantics, which advances a contract by one
-time unit. We write $c \cRed \rho \tau c'$, to denote that $c$ is
-advanced to $c'$ in the environment $\rho$, where $\tau \in
-\type{Trans}$ indicates the transfers that are necessary (and
-sufficient) in order to advance $c$ to $c'$.
