+        When building a recipe, the OpenEmbedded build system performs
+        various QA checks on the output to ensure that common issues are
+        detected and reported.
+        Sometimes when you create a new recipe to build new software,
+        it will build with no problems.
+        When this is not the case, or when you have QA issues building any
+        software, it could take a little time to resolve them.

+    <para>
+        While it is tempting to ignore a QA message or even to
+        disable QA checks, it is best to try and resolve any
+        reported QA issues.
+        This chapter provides a list of the QA messages and brief explanations
+        of the issues you could encounter so that you can properly resolve
+        problems.

+
+    <para>
+        The next section provides a list of all QA error and warning
+        messages based on a default configuration.
+        Each entry provides the message or error form along with an
+        explanation.

+This section uses the <para><code> construct to enable permalinks for the
+various QA issue and warning messages.  The file templates/qa-code-permalinks.xsl
+is used to locate the construct and generate the permalink.  This solution
+leverages the fact that right now this section in the ref-manual is the only
+place is all the YP docs that uses the <para><code> construct.  If, in the
+future, that construct were to appear in the ref-manual, a generic permalink
+would be generated for the text between <code></code>.  If a better solution
+can be found then it should be implemented.  I can't find one at the moment.

+                    It is common for upstream software projects to default to
+                    stripping debug symbols for output binaries.
+                    In order for debugging to work on the target using
+                    <filename>-dbg</filename> packages, this stripping must be
+                    disabled.

+                    Depending on the build system used by the software being
+                    built, disabling this stripping could be as easy as
+                    specifying an additional configure option.
+                    If not, disabling stripping might involve patching
+                    the build scripts.
+                    In the latter case, look for references to "strip" or
+                    "STRIP", or the "-s" or "-S" command-line options being
+                    specified on the linker command line (possibly
+                    through the compiler command line if preceded with "-Wl,").
+                    <note>
+                        Disabling stripping here does not mean that the final
+                        packaged binaries will be unstripped.
+                        Once the OpenEmbedded build system splits out debug
+                        symbols to the <filename>-dbg</filename> package,
+                        it will then strip the symbols from the binaries.
