The MATHEMATICA package HYP consists of the files hyp.m, summatio.m, summatio.mgl, transfor.m, transfor.mgl, transfor.mli, contig.m. In addition there is the file output. There is also the possibility to use Gosper's and Zeilberger's algorithms within the package HYP. To be able to do so you need Peter Paule's and Markus Schorn's MATHEMATICA implementation of these algorithms which is available via e-mail request to peter.paule@risc.uni-linz.ac.at. Copy all the files in your MATHEMATICA input directory. The file hyp.m should be loaded at the very beginning of your MATHEMATICA session. The package should work with any version of MATHEMATICA with the exception of Gosper's and Zeilberger's algorithms which require at least MATHEMATICA 2.0. For further help consult the manual (file hypm.ps) and the tutorial (file hyp_hypq.ps). If you want to be informed about updates of this package send an e-mail to kratt@pap.univie.ac.at.
