We offer a Maple package {\tt Poincare\_Series} for calculating the Poincar\'e series for the algebras of invariants/covariants of binary forms, for the algebras of joint invariants/covariants of several binary forms, for the kernel of Weitzenb\"ock derivations and for the multivariate Poincar\'e series of algebras of joint invariants/covariants of several binary forms.
