1.  Invoke the IDL compiler to compile the interface definition file
        test.idl and keep the generated C source modules.  Only server
        files are generated.  The server stub default filename is
        overridden by creating a file named test_ss.c for the server
        stub module.

             $ idl test.idl -keep c_source -client none -sstub test_ss.c

    2.  Invoke the IDL compiler to compile the interface definition file
        test.idl, but do not run the C preprocessor.  The manager entry
        point vector is not defined in the generated server stub module.
        The IDL compiler searches the parent directory of the current
        directory for any IDL files that test.idl could import.  The
        generated output files are located in the output subdirectory
        under the current directory.

             $ idl test.idl -no_cpp -no_mepv -I.. -out [.output]
