[petsc-dev] AD support in PETSc?

[Stefano Zampini]

Should the references to ADIFOR listed below be removed? It seems PETSc
does no longer provide support for automatic differentiation. I never used
AD support in PETSc, but I was considering adding some reverse mode support
to compute the transpose of the Jacobian matrices in adjoint computations.
May ask why was it removed?
