[petsc-users] Hypre through Petsc: BoomerAMG options

Hei!
I was going through the Petsc user archives when I came across a
discussion with Barry Smith regarding use of BoomerAMG through Petsc
(http://lists.mcs.anl.gov/pipermail/petsc-users/2006-October/000692.html).

What I did understand from that is some of the Hypre options cannot
be accessed through Petsc. But options like Pilut are available as
preconditioners or solvers depnding on ksptype.
I am trying to use ILU smoothening to BoomerAMG (Hypre's manual lists the
smoothers available and the function calls). The questions that remain
after going through that discussion are:

1.  Can a smoothening option in hypre's boomerAMG could be chosen at all
using Petsc?
2.  Could the function calls phrases used in Hypre itself be somehow
employed in the Petsc code?

Would be really grateful for any advice. Since I am using an IDE to build
the code, non-command line option tricks would also be of great help.
