<p>The common interfaces have been defined in the new abstract classes
that form the core of TAO's pluggable protocol framework, e.g.,
<tt>TAO_Connector</tt>,
<tt>TAO_Acceptor</tt>,
<tt>TAO_Profile</tt>
and <tt>TAO_Transport</tt>. Two new mechanisms for keeping track of supported
transport protocols are the
<tt>TAO_Connector_Registry</tt> and
<tt>TAO_Acceptor_Registry</tt>,
which are essentially Abstract Factories that produce the right types of
connector, acceptors, and transports.
