Dear petsc developers.

While I was applying the preconditioner in contact with the FEM code, I had
some questions.

How can I apply the AMG PC and the multilevel Schwarz PC in the FEM code?
Purpose is to compare which PC is better in the FEM code with contact

In my case, the Jacobi PC could be easily applied as shown in the example
below. However, AMG and multilevel have too many options.

ex) ./app -ksp_type gmres -pc_type jacobi -ksp_view
