+                Build history collects similar information on the contents
+                of SDKs (for example, <filename>meta-toolchain</filename>
+                or <filename>bitbake -c populate_sdk imagename</filename>)
+                to that which it collects for images.
+                The files produced for each SDK are as follows:

+                        owner, group, size, and symlink information.
+                        This includes both the host and target parts
+                        of the SDK.
