  The library provides a set of C++/Python functions for computing cross
sections of ultraperipheral collisions of high energy particles under the
equivalent photons approximation. Cross sections are represented through
multiple integrals over the phase space. The integrals are calculated through
recurrent application of algorithms for one dimensional integration. The paper
contains an introduction to the theory of ultraperipheral collisions, discusses
the library approach and provides a few examples of calculations.
