As its name (Dynamic Page Lister) implies, DPL is a report generator for MediaWikis. This is the most important extension we provide. The name of this website (dpldemo) is derived from the idea to demonstrate the many uses of DPL. DPL is a true monster in terms of functionality. Although there is a detailed DPL manual most people will find it easier to look for an existing DPL example which is similar to their needs.
