             The items below are features you can use with
-            <link linkend='var-DISTRO_FEATURES'><filename>DISTRO_FEATURES</filename></link>.
-            Features do not have a one-to-one correspondence to packages, and they can
-            go beyond simply controlling the installation of a package or packages.
-            Sometimes a feature can influence how certain recipes are built.
-            For example, a feature might determine whether a particular configure option
-            is specified within <filename>do_configure</filename> for a particular
-            recipe.

+            In most cases, the presence or absence of a feature translates to

+            <filename>do_configure</filename> for the recipes that optionally
+            support the feature.
