 * This is a command line tool that can be used to purge expired tokens
 * from the OAuth database. It requires you specify a pocket client id
 * before running. Currently, access tokens created from pocket should
 * not be deleted even if expired.
 *
 * Example usage:
 *
 * node purge_expired_tokens.js --config dev --pocket-id dcdb5ae7add825d2 --token-count 10000 --delay-seconds 1
 *
