We present a method to compute the Laurent expansion of the two-loop sunriseintegral with equal non-zero masses to arbitrary order in the dimensionalregularisation $\varepsilon$. This is done by introducing a class of functions(generalisations of multiple polylogarithms to include the elliptic case) andby showing that all integrations can be carried out within this class offunctions.

The iterated structure of the all-order result for the two-loop sunrise integral
