+                    When a recipe inherits the
+                    <link linkend='ref-classes-extrausers'><filename>extrausers</filename></link>
+                    class, this variable provides image level user and group
+                    operations.
+                    This is a more global method of providing user and group
+                    configuration as compared to using the
+                    <link linkend='ref-classes-useradd'><filename>useradd</filename></link>
+                    class, which ties user and group configurations to a
+                    specific recipe.

+                    The set list of commands you can configure using the

+                    <filename>extrausers</filename> class.
+                    These commands map to the normal Unix commands of the same
+                    names:
