A function for computing generating functions

Hi,

I noticed that people usually compute generating functions
made of a fraction of two polynomials from the initial terms
of the sequence with the help of the LLL algorithm when
implemented (for instance with Pari/GP). Since Maxima
doesn't have this algorithm, I imaginated another way to
do the same thing and found a very efficient method with
some special kind of continued fractions.

Please, if you are intesrested by generating functions,
have a look at http://tbaruchel.free.fr/ggf.mac

Of course, I would be very honorated if this file can be
archived somewhere or distributed with other contributions
in Maxima sources.

Regards,
