## In this chapter functions are provided to perform simplicial blowups as
## well as the resolution of isolated singularities of certain types of
## combinatorial <M>4</M>-manifolds. As of today singularities where the
## link is homeomorphic to <M>\mathbb{R}P^3</M>, <M>S^2 \times S^1</M>,
## <M>S^2 \dtimes S^1</M> and the lens spaces <M>L(k,1)</M> are supported.
## In addition, the program provides the possibility to hand over additional
## types of mapping cylinders to cover other types of singularities.<P/>
##
## Please note that the program is based on a heuristic algorithm using
## bistellar moves. Hence, the search for a suitable sequence of bistellar
## moves to perform the blowup does not always terminate. However,
## especially in the case of ordinary double points (singularities of type
## <M>\mathbb{R}P^3</M>), a lot of blowups have already been successful.
