+                    A list of aliases by which a particular recipe can be
+                    known.

+                    <filename><link linkend='var-PN'>PN</link></filename>

+                    list.
+                    If a recipe uses <filename>PROVIDES</filename>, the
+                    additional aliases are synonyms for the recipe and can
+                    be useful satisfying dependencies of other recipes during
+                    the build as specified by

+                    Consider the following example

+                    The <filename>PROVIDES</filename> statement results in
+                    the "libav" recipe also being known as "libpostproc".
