 We think of this map as being associated to a surgery which cuts $M$ out of $M\cup_E R$ and
 replaces it with $N$, yielding $N\cup_E R$.
+(This is a more general notion of surgery that usual --- $M$ and $N$ can be any manifolds
+which share a common boundary.)

 By the `blob cochains' of a manifold $X$, we mean the $A_\infty$ maps of $\bc_*(X)$ as a $\bc_*(\bdy X)$ $A_\infty$-module.
