-            This list is a place holder of content existed from previous work
-            on the manual.
-            Some or all of it probably needs integrated into the subsections
-            that make up this section.
-            For now, I have just provided a short glossary-like description
-            for each variable.
-            Ultimately, this list goes away.
+            These checksums are stored in
+            <link linkend='var-STAMP'><filename>STAMP</filename></link>.
+            You can examine the checksums using the following BitBake command:
+            <literallayout class='monospaced'>
+     $ bitbake-dumpsigs
+            </literallayout>
+            This command returns the signature data in a readable format
+            that allows you to examine the inputs used when the
+            OpenEmbedded build system generates signatures.
+            For example, using <filename>bitbake-dumpsigs</filename>
+            allows you to examine the <filename>do_compile</filename>
+            task's “sigdata” for a C application (e.g.
+            <filename>bash</filename>).
+            Running the command also reveals that the “CC” variable is part of
+            the inputs that are hashed.
+            Any changes to this variable would invalidate the stamp and
+            cause the <filename>do_compile</filename> task to run.
