System options: -d|--directory=DIR By default, load and dump will use the CSV files in the pokedex install directory. Use this option to specify a different directory. Load options: -D|--drop-tables Drop all tables before loading data. -S|--safe Disable engine-specific optimizations. -r|--recursive Load (and drop) all dependent tables.
