  We present MaRTIn, an extendable all-in-one package for calculating
amplitudes up to two loops in an expansion in external momenta or using the
method of infrared rearrangement. Renormalizable and non-renormalizable models
can be supplied by the user; an implementation of the Standard Model is
included in the package. In this manual, we discuss the scope and functionality
of the software, and give instructions of its use.
