[GiNaC-list] 'full' differentiation?

is there an easy way to get 'full' differentiation, ie, of all
variables, instead of only the main variable?  Example: Given symbols x,u,
diff(x/u, x) would then produce (u-u'x)/u^2. At the moment, I'm
abusing psi to get the effect but that is certainly not the best way.
