Subject: hsum, qsum and CAOP updated

Wolfram Koepf's Maple packages hsum6.mpl and qsum6.mpl for
(q-)hypergeometric
summation (see OP-SF NET 8.2 #13, March 2001)
have now been updated in order to let them work correctly with Maple 9
(and earlier Maple versions, certainly down to Maple 7).
The new versions are renamed hsum9.mpl and qsum9.mpl, respectively.
The Maple help database maple.hdb for these packages has remained
unchanged.
The three files can be downloaded from

Rene Swarttouw's 1996 package CAOP for online calculations in Maple
of formulas for orthogonal polynomials belonging to the Askey scheme
is maintained since 2001 by Tom Koornwinder (ee OP-SF NET 8.6 #14,
November 2001). Since then the URL of the CAOP webpage has changed into

http://amstel.science.uva.nl:7090/CAOP/

Recently, missing plot files have been added to CAOP (work by Wolfram
Koepf
and Rene Swarttouw). Also, CAOP is now running in Maple 9 with the
package hsum9.
Extensions with computations for q-hypergeometric orthogonal
polynomaials
are expected later this year.
