-class Session:
-    """
-    This class represents a TLS session.
-
-    TLS distinguishes between connections and sessions.  A new
-    handshake creates both a connection and a session.  Data is
-    transmitted over the connection.
-
-    The session contains a more permanent record of the handshake.  The
-    session can be inspected to determine handshake results.  The
-    session can also be used to create a new connection through
-    "session resumption". If the client and server both support this,
-    they can create a new connection based on an old session without
-    the overhead of a full handshake.
-
-    The session for a L{tlslite.TLSConnection.TLSConnection} can be
-    retrieved from the connection's 'session' attribute.
