the Plug-in Framework</title><shortdesc>Clients of a plug-in framework use the C++ APIs provided by the

framework for interaction with the framework. Client calls to the interface

definition are translated directly through <apiname>REComSession</apiname> into

loading and unloading of the correct implementation library together with

construction and destruction of an appropriate interface implementation. </shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>
