 * The limits of the query can be set with the `MINOFFSET` and `MAXOFFSET` tags directly after the `PAGESIZE` tag. The resulting query will ask about the statements in the interval [`MINOFFSET`, `MAXOFFSET`]. Note that `MINOFFSET` must be smaller than `MAXOFFSET`! If both `SOURCE` and `TARGET` are restricted, a warning is generated.
