 Purpose:
 A library for computing invariants of curves
 Author:
 Peter Chini, chini@rhrk.unikl.de
 Overview:
 This library provides a collection of procedures for computing invariants
of curve singularities. Invariants that can be computed are:
 the delta invariant
 the multiplicity of the conductor: the length of Normalization(R)/C,
where C denotes the conductor
 the Deligne number
 the colength of derivations along the normalization  the length of
Der(Normalization(R/I)) / R/I
In addition, it is possible to compute the conductor of a ring S = R/I,
where R is a (localized) polynomial ring.
 Theory:
 Computing the Deligne number of curve singularities and an algorithmic framework for
