1.0.1 `pfp_omega'
-----------------

pfp_omega(P)
     :  It returns the Gauss-Manin connection Omega  for the
     generalized hypergeometric function   P F P-1 (aa1,aa2, ...; cc1,
     cc2, ...;x) .

   Description:

     Define a vector valued function Y of which elements are
     generalized hypergeometric function f_1=F and  f_2=xdf_1/dx, f3=xd
     f_2/dx, ...   It satisfies  dY/dx= Omega Y.   Generalized
     hypergeometric function is defined by the series  p F p-1(aa1,aa2,
     ...; cc1, cc2, ...;x) =  sum(k=0,infty; (aa1)_k (aa2)_k .../(
     (1)_k (cc1)_k (cc2)_k ... ) x^k)


   Example:
      pfp_omega(3);
