The <em>Hypergeometric</em> operator provides simplifications for the 
generalized hypergeometric functions. 
The <em>Hypergeometric</em> operator is included in the package specfn2.

</TT></PRE><P>The special case where the length of the first list is equal to 2 
and 
the length of the second list is equal to 1 is often called 
``the hypergeometric function'' (notated as 2F1(a1,a2,b;x)).
