Hypergeometric function theory and Feynman Integral calculus go hand in hand. A series of
recent investigations that culminated in the construction of several Mathematica packages that are
based on Mellin-Barnes techniques, Method of Regions, hypergeometric function theory, etc., is
reviewed in this talk to encourage the community to explore the use of these packages. Twoloop integrals appearing in chiral perturbation theory are a typical example that will be used for
purposes of illustration.
