10Introduction
11------------
12
13The features of the package `NumericalSgps` include
14
15- defining numerical semigroups;
16- computing several properties of numerical semigroups, namely: multiplicity, Frobenius number, (minimal) system of generators, Apéry set, gaps, fundamental gaps, etc.;
17- perform several operations on numerical semigroups and ideals, namely: intersection, quotient by an integer, decompose into irreducible semigroups, add a special gap, ...;
18-computing and testing membership to relevant families of numerical semigroups.

20There is a manual in the sub-directory `doc` written using the GAP package
21gapdoc which describes the available functions in detail. The pdf, html
22versions of the manual are also available there.
