qGeneratingFunctions
Short Description
The qGeneratingFunctions.m package by
Christoph Koutschan
provides commands for manipulating univariate q-holonomic sequences
and power series: closure properties, conversion between q-difference
and q-differential equations, guessing.

A Note on Encoded Files
This package contains one or more Mathematica input files which are encoded. Those files
cannot be read or modified directly as plain text, but can be loaded into
Mathematica just like any normal input file (i.e., with
<<"file" or
Get["file"]).
There is no need (and also no way) to decode them by using additional software
or a special key.
If loading an encoded file causes a syntax error, open it with a
text editor and remove any blank lines at the beginning (for some
reason your Mac could have inserted them silently...).
The Package
The package is contained in the Mathematica input file
and is accompanied by the Mathematica notebook
The current version is compatible with all Mathematica
versions between 5.2 and 8.0.
It might not run properly on earlier versions.

The theoretical background of qGeneratingFunctions is described in

The examples presented there are collected in the Mathematica notebook
demo.nb .
To use the implementation it is sufficient to study the notebook.
