-The command line flags are grouped into `Edit/Create`, `Find/List` and `Help` actions. The first group of actions allows you to work with password databases and perform create/edit as well as encrypt/decrypt actions. The second set of actions allows you to work with an active decrypted database and view/search/list entries.
