1. F4

	array.c, gr.c (still experimental)

2. Weyl algebra

	dist.c, distm.c : product of monomials (weyl_mul*)
	Q.c : coefficients of the expansion of D^k*x^l (mkwc, mkwcm)

    Note that the current implementation and specification are too ad hoc.

	If ctrl("do_weyl",1) is executed, then all monomial operations are
	done in Weyl algebra. If the length of the exponent of a monomial
	is n=2m, then it is regarded as an element of Q<x1,...,xm,Dx1,...,Dxm>.
	If the length is n=2m+1, then it is a regarded as an element of
	Q[h]<x1,...,xm,Dx1,...,Dxm>, where h is the homogenization variable.
	The order specification is the same as in the commutative case, so
	one should use matrix order to realize natural orderings in Weyl
	algebra. Negative waits have not yet been supported.
