Comment:
Apply trac4539_libplural.patch
It turned out that the old patch did not apply, since meanwhile the
libsingular options are dealt with in a different way. I have rebased the
patch, and also adopted the new option syntax.
However, not all is good. Here is one error that I just found:
{{{
sage: A.<x,y,z> = FreeAlgebra(QQ, 3)
sage: H = A.g_algebra({y*x:x*y-z, z*x:x*z+2*x, z*y:y*z-2*y})
sage: H.inject_variables()
Defining x, y, z
sage: I = H.ideal([y^2, x^2, z^2-H.one_element()],coerce=False)
sage: G = vector(I.gens()); G

So, there remains work to do!
