//
// Throughout this parse module, we return E_NOINTERFACE
// to indicate invalid command line syntax/parameters.
// This is to explicitly distinguish from E_INVALIDARG that may
// be returned by the CLI dll: we wish to distinguish a syntax error
// detected by the parser from a syntax error detected  by the CLI dll
// because in the latter case we do not print the usage for the interface.
// Whereas for errors detected by the parser, we *do* print the usage.
// This rule needs to be strictly adhered to
