+        The library package (<filename>lib_package</filename>) class
+        supports recipes that build libraries and produce executable
+        binaries, where those binaries should not be installed by default
+        along with the library.
+        Instead, the binaries are added to a separate
+        <filename>${</filename><link linkend='var-PN'><filename>PN</filename></link><filename>}-bin</filename>
+        package to make their installation optional.
