 header files of the client interfaces are installed into
       <TT
CLASS="VARNAME"
>includedir</TT
> and are namespace-clean. The
       internal header files and the server header files are installed
       into private directories under <TT
CLASS="VARNAME"
>includedir</TT
>. See
       the documentation of each interface for information about how to
       access its header files. Finally, a private subdirectory will
       also be created, if appropriate, under <TT
CLASS="VARNAME"
>libdir</TT
>
