 Fields on $n$-manifolds will be enriched over $\cS$.
 Good examples to keep in mind are $\cS = \Set$ or $\cS = \Vect$.

 One of the advantages of string diagrams over pasting diagrams is that one has more
 flexibility in slicing them up in various ways.
 In addition, string diagrams are traditional in quantum topology.
-The diagrams predate by many years the terms ``string diagram" and ``quantum topology", e.g. \cite{MR0281657,MR776784} % both penrose

 In this subsection we briefly review the construction of a TQFT from a system of fields and local relations.
 As usual, see \cite{kw:tqft} for more details.

 maps $\lf(\bd W)\to \c$.
