The authors wish to thank the contributors of the package. A full list with the help received is available in Appendix C. We are also in debt with H. Schönemann, C. Söeger and M. Barakat for their fruitful advices concerning SingularInterface, Singular, Normaliz, NormalizInterface and GradedModules.
The maintainers want to thank the organizers of GAPDays in their several editions.
The authors also thank the Centro de Servicios de Informática y Redes de Comunicaciones (CSIRC), Universidad de Granada, for providing the computing time, specially Rafael Arco Arredondo for installing this package and the extra software needed in alhambra.ugr.es, and Santiago Melchor Ferrer for helping in job submission to the cluster.
The first and second authors warmly thank María Burgos for her support and help.
