[petsc-dev] GAMG documentation very thin?

[Barry Smith]

   The manual page for    PCGAMG and the users manual seem very very thin are how to use PGGAMG, no mention of various useful options and no seeming mention of near null spaces etc that, as I understand it, care important for getting good convergence. Remember this is a library, not a framework?

Library, something you get and use. Framework, something you write a proposal with the authors of and then they may have some junior person help you use it until the grant runs low or they are working on another proposal.
