-     * Components are fluid systems which provide the
-     *  thermodynamic relations for the liquid and gas phase of a single
-     *  chemical species or a fixed mixture of species. Their main purpose
-     *  is to provide a convenient way to access these quantities from
-     *  full-fledged fluid systems. Components are not supposed to be used
-     *  by models directly.

+     * chemical species or a _fixed_ mixture of species.
+     * Fluid systems use components to compute thermodynamic quantities of phases.
