  A review is given of attempts to bridge the gap between everyday particle and
nuclear physics - involving many quarks - and the basic underlying theory of
QCD that can only be evaluated exactly for few quark systems. Even the latter
requires the original theory of QCD to be discretised to give Lattice QCD - but
this modification can still yield exact results for the original theory. These
LQCD results can then be considered on a similar footing to experimental data -
namely as cornerstones that must be fitted by phenomenological models. In this
way, the hope is that "QCD inspired" models can become more and more "QCD
based" models, by fixing - in the few-quark case where LQCD can be carried out
- the form of these models in such a way that they can be extended to
multi-quark systems.
