Ok - I just thought it was kind of odd that it has some data members and stuff - but then doesn't do anything by default.
We use the command-line options for PETSc... but we set them programmatically. Gives us the most flexibility because there are thousands of them and they are always changing. Thanks for the reply - I was just making sure I wasn't missing anything.
