Every command gets long help and examples, descriptions in imperative sentence case, and a warn-only TestCommandsDocumented over bonfire.CheckDocs. The plugin logs through a diary component logger instead of the process default logger. Requires SummerCMS v0.4.0; command names and flags unchanged. user:token:create and user:token:list gain --json, user:backfill-handles a progress bar; planning IDs leave the descriptions.
