1153:   Logically Collective on the communicator passed in `PetscOptionsBegin()`

1155:   Input Parameters:
1156: + opt  - option name
1157: . text - short string that describes the option
1158: - man  - manual page with additional information on option

1160:   Output Parameters:
1161: + viewer - the viewer
1162: . format - the PetscViewerFormat requested by the user, pass `NULL` if not needed
1163: - set    - `PETSC_TRUE` if found, else `PETSC_FALSE`

1165:   Level: beginner

1167:   Notes:
1168:   Must be between a `PetscOptionsBegin()` and a `PetscOptionsEnd()`
