+                    Determines which recipe should be given preference for
+                    cases where multiple recipes provide the same item.
+                    Functionally,
+                    <filename>PREFERRED_PROVIDERS</filename> is identical to
+                    <link linkend='var-PREFERRED_PROVIDER'><filename>PREFERRED_PROVIDER</filename></link>.
+                    However, the <filename>PREFERRED_PROVIDERS</filename>
+                    variable lets you define preferences for multiple
+                    situations using the following form:
+                    <literallayout class='monospaced'>
+     PREFERRED_PROVIDERS = "xxx:yyy aaa:bbb ..."
+                    </literallayout>
+                    This form is a convenient replacement for the following:
+                    <literallayout class='monospaced'>
+     PREFERRED_PROVIDER_xxx = "yyy"
+     PREFERRED_PROVIDER_aaa = "bbb"
