+        The C/C++ Compiler Cache (<filename>ccache</filename>) class enables
+        this cache for the build.
+        This class is used to give a minor performance boost during the build.
+        However, using the class can lead to unexpected side-effects.
+        Thus, it is recommended that you do not use this class.
+        See <ulink url='http://ccache.samba.org/'></ulink> for information on
+        the C/C++ Compiler Cache.
