*q*-holonomic sequences and power series. The package is intended as a

*q*-analogue of the Maple package gfun and the Mathematica package GeneratingFunctions. It provides commands for addition, multiplication, and substitution of these objects, for converting between various representations (

*q*-differential equations,

*q*-recurrence equations,

*q*-shift equations),...
