regrid broken?

s.regrid(u)

gives:

You cannot pass a transient Variable to the regridder but you need to pass a grid as documented
here.

I am still working on publishing the API documentation. You can find the regrid function here

import cdms2
import vcs
f=cdms2.open(vcs.sample_data+"/clt.nc")
s=f("clt")
u=f("u")
s.regrid(u.getGrid())
