DPL is a powerful tool, allowing users to construct queries with specific constraints to display lists of certain pages, template arguments, and many other things, and define a (custom) display output for the data. Its syntax is necessarily complex, and incorrect use can substantially slow page loads. DPL is primarily used in Kirby Wiki within templates in the Database.
