+                    This variable lists packages BitBake uses when it builds
+                    an SDK installer, which is used to extract and set up a
+                    cross-development environment.
+                    The packages specified by this variable are part of the
+                    toolchain set that runs on the
+                    <link linkend='var-SDKMACHINE'><filename>SDKMACHINE</filename></link>.
+                    When you build an SDK installer using BitBake, a set of
+                    default tasks apply.
+                    The tasks you specify here are added to those defaults.
