-
-Commands:
- help Displays this message.
- lookup [thing] Look up something in the Pokédex.
-
-System commands:
- load Load Pokédex data into a database from CSV files.
- dump Dump Pokédex data from a database into CSV files.
- reindex Rebuilds the lookup index from the database.
- setup Combines load and reindex.
- status No effect, but prints which engine, index, and csv
- directory would be used for other commands.
-
-Global options:
- -e|--engine=URI By default, all commands try to use a SQLite database
- in the pokedex install directory. Use this option (or
- a POKEDEX_DB_ENGINE environment variable) to specify an
- alternate database.
- -i|--index=DIR By default, all commands try to put the lookup index in
- the pokedex install directory. Use this option (or a
- POKEDEX_INDEX_DIR environment variable) to specify an
- alternate loction.
- -q|--quiet Don't print system output. This is the default for
- non-system commands and setup.
- -v|--verbose Print system output. This is the default for system
- commands, except setup.
-
-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.
- -D|--drop-tables With load, drop all tables before loading data.
-
- Additionally, load and dump accept a list of table names (possibly with
- wildcards) and/or csv fileames as an argument list.
