We present a new software package in the computer algebra system Risa/Asir NT92, named PGB, for computing parametric Gröbner bases in various domains and related objects. A parametric Gröbner basis is a Gröbner basis for a polynomial ideal with parametric coefficients. One can download the package PGB from the following website. http://www.risc.uni-linz.ac.at/research/compalg/software/
