The demand for precision predictions in the field of high-energy physics has dramatically increased over the past years. To facilitate higher-order computations we aim to devise a package that automatizes as many steps as possible. The package is designed to integrate FeynRules, a Mathematica package, with QGRAF, a Fortran program for
generating Feynman diagrams, with the toolchains in the computer algebra system FORM, often used in loop computation. So the idea is to have a package where given a Lagrangian and process under investigation it can compute the amplitude and thereby also amplitude square and eventually gives you the integrand which needs to be solved further using the loop integral techniques.
