29 * @class AIAutoReplyPlugin
30 * @brief Provides AutoReply functionality for the state system
32 * This class implements the state system behavior for auto-reply. If auto-reply status is active on an account,
33 * initial messages recieved on that account will be replied to automatically. Subsequent messages will not receive
34 * a reply unless the chat window is closed.
36 * This is the expected behavior on certain protocols such as AIM, and considered a convenience on other protocols.
38 @implementation AIAutoReplyPlugin
41 * @brief Initialize the auto-reply system
43 * Initialize the auto-reply system to monitor account status. When an account auto-reply flag is set we begin to
44 * monitor chat messaging and auto-reply as necessary.
