layer against other layers that contain the same recipe - effectively
letting you control the precedence for the multiple layers.
The precedence established through this variable stands regardless of a
- recipe's version (<filename>PV</filename> variable).
+ recipe's version
+ (<link linkend='var-PV'><filename>PV</filename></link> variable).
For example, a layer that has a recipe with a higher <filename>PV</filename> value but for
which the <filename>BBFILE_PRIORITY</filename> is set to have a lower precedence still has a
lower precedence.</para>
