Forked it to change output behavior (WIP). If a single table name is provided, current behavior creates multiple files: table0 (all tables before), table01 (the expected table), table02 (all tables after). (My) Expected behavior is to only get table02. This is particularly useful in case trying to extract a table from a large SQL document, so no time (and resources) is wasted for the unwanted tables.
