+asyncronous IO and provides event-based APIs. It has three basic data
 structures:
 
 - `struct mg_mgr` is an event manager that holds all active connections
 - `struct mg_connection` describes a connection
 - `struct mbuf` describes data buffer (received or sent data)
 
-Connections could be either *listening*, *outbound* or *inbound*.  Outbound
-connections are created by `mg_connect()` call.  Listening connections are
-created by `mg_bind()` call.  Inbound connections are those accepted by a
-listening connection.  Each connection is described by `struct mg_connection`
