<h4>1.1 <span class="Heading">What is the purpose of the this package?</span></h4>
<p>Normaliz <a href="chapBib.html#biBnormaliz">[BIRS18]</a> is a software for computations with rational cones and affine monoids. It pursues two main computational goals: finding the Hilbert basis, a minimal generating system of the monoid of lattice points of a cone; and counting elements degree-wise in a generating function, the Hilbert series. As a recent extension, Normaliz can handle unbounded polyhedra. The Hilbert basis computation can be considered as solving a linear diophantine system of inhomogeneous equations, inequalities and congruences.</p>
<p>This package encapsulates a libnormaliz cone and gives access to it in the <strong class="pkg">GAP</strong> environment. In this way <strong class="pkg">GAP</strong> can be used as interactive interface to libnormaliz.</p>
