TSIL: a program for the calculation of two-loop self-energy integrals. Nature of problem: Numerical evaluation of dimensionally regulated Feynman integrals needed in two-loop self-energy calculations in relativistic quantum field theory in four dimensions. Solution method: Analytical evaluation in terms of polylogarithms when possible, otherwise through Runge-Kutta solution of differential equations (Source: http://cpc.cs.qub.ac.uk/summaries/)
