+            Several varflags are useful for controlling how signatures are
+            calculated for variables.
+            For more information on this process, see the

+                    Specifies a space-separated list of additional
+                    variables to add to a variable's dependencies
+                    for the purposes of calculating its signature.
+                    Adding variables to this list is useful, for example, when
+                    a function refers to a variable in a manner that
+                    does not allow BitBake to automatically determine
+                    that the variable is referred to.

+                    If set, instructs BitBake to ignore the actual
