We present methods for the numerical evaluation of the master integrals that appear in the calculation of scattering amplitudes at higher order in perturbative quantum field theory. We follow the general strategy of solving first-order ordinary differential equations through series expansion. We have collected these procedures in an open source computer program that we dub \Line{}. Boundary conditions can be provided by the user or computed internally using the method of expansion by regions. Illustrative examples are also given.
