+usage: pokedex {command} [options...]
+Run `pokedex setup` first, or nothing will work!
+
+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.
+    setup               Loads Pokédex data into the right place and creates a
+                        lookup index in the right place.  No options or output.
+                        This will blow away the default database and index!
+
+Options:
+    -d|--directory      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.
+    -e|--engine=URI     By default, all commands try to use a SQLite database
+                        in the pokedex install directory.  Use this option to
+                        specify an alternate database.
+    -q|--quiet          Turn off any unnecessary status output from dump/load.
