Since <A HREF="../Sys/PetscOptionsInsert.html#PetscOptionsInsert">PetscOptionsInsert</A>() is automatically called by <A HREF="../Sys/PetscInitialize.html#PetscInitialize">PetscInitialize</A>(),
the user does not typically need to call this routine. <A HREF="../Sys/PetscOptionsInsert.html#PetscOptionsInsert">PetscOptionsInsert</A>()
can be called several times, adding additional entries into the database.
