+        The <filename>distutils3</filename> class supports recipes for Python
+        version 3.x extensions, which are simple.
+        These recipes usually only need to point to the source's archive and
+        then inherit the proper class.
+        Building is split into two methods depending on which method the
+        module authors used.
