Sounds like a good idea. I guess we also put the options manager in there, right? |
Yeah exactly. Also whatever clever ideas happen with the appctx. |

A lot of users have been cargo-culting Firedrake's PETSc code for a long time (especially the options manager). This is even happening outside of the Firedrake user base. I (and others) think that it therefore makes some sense to have an external mini package that can store this sort of thing.
I have started this process off by writing petsctools. At the moment it does just the thing I want which is to warn users if their PETSc and petsc4py versions do not match. Also if
PETSC_DIRis set but does not match what petsc4py thinks then an exception is raised.If people are happy I will move petsctools into the firedrakeproject organisation and make a release.
