           SHORT="Common back-end to Atlas"
cat << EOF
Eris is designed to simplify client development (and promote code reuse) by providing a common system to deal with the back-end Atlas tasks. Notably, Eris encapsulates most of the work in getting Atlas entities available on your client, logging into a server, and managing updates from the server. Once the entities are made available locally, Eris also manages updating them as required. Thus it can be considered as a session layer above Atlas, providing persistent (for an entire gaming session) objects as opposed to transient Atlas ones. It handles the client-side implementation of the meta-server protocol, and querying game servers; out-of-game (OOG) operations (via the Lobby and Rooms), and most important in-game (IG) operations such as entity creation, movement and updates.
