+//! The following is a proposal for quests in Veloren. A server side quest system would maintain
+//! the necessary conditions for the quests. Players would be given a `Quests` component which
+//! would store current quests. Each quest consists of a name and a vector of quest conditions.
+//! These conditions are popped off the vector until it is empty. At that point the quest is
+//! complete. Here is a sample quest:
+//!
+//! ```
+//! Quest {
+//!     name: "Escort Bob safely to Thead for Joe",
+//!     conditions: [
+//!         Find(RtSimEntity(3, "Bob"), QuestLocation {
+//!                                         kind: Site("Scrin"),
+//!                                         location: None,
+//!                                     }),
+//!         Escort(RtSimEntity(3, "Bob"), QuestLocation {
+//!                                         kind: Site("Thead"),
+//!                                         location: None,
+//!                                     }),
+//!         CollectReward(QuestItem{
+//!                             item_definition_id: "common.items.utility.coins",
+//!                             quantity: 1000,
+//!                         }),
+//!     ],
+//! }
+//! ```
+//!
+//! The quest must be completed in order. Failure would be monitored by the server side quest
+//! system. (Eg. escort conditions would fail if the escorted entity died.)
