Default convergence test used in PETSc

Hi

I am trying to determine the default convergence test used by PETSc.
Your pdf user's guide states the default test is based on the decrease
of the residual norm relative to the right-hand-side while your html
documentation for KSPDefaultConverged() seems to imply that the default
test is based on the decrease of the residual norm relative to the
initial residual norm. Can you tell me which is actually the default?

Regards

Stephen
