  For many years, theorists have calculated formulas for useful quantities in
general gauge-Yukawa theories. However, these cookbooks are often very
difficult to use since the general notation is far removed from practical model
building.
  In this paper, we present the structure delta which allows us to use a
surprisingly convenient notation that bridges the gap between general
gauge-Yukawa theories and specific models. This is particularly useful for the
computation of beta functions, but can also be extended to handle spontaneous
symmetry breaking, the effective potential and a variety of other quantities.
We will introduce it using the standard model of particle physics and a toy
model with an SU(N_c) gauge symmetry.
