         <para>
-            Welcome to the Yocto Project Development Manual!
-            This manual gives you an idea of how to use the Yocto Project to develop embedded Linux
-            images and user-space applications to run on targeted devices.
-            Reading this manual gives you an overview of image, kernel, and user-space application development
-            using the Yocto Project.
-            Because much of the information in this manual is general, it contains many references to other
-            sources where you can find more detail.
-            For example, detailed information on Git, repositories and open source in general
-            can be found in many places.
-            Another example is how to get set up to use the Yocto Project, which our Yocto Project
-            Quick Start covers.
+            Yocto bundles a number of tracing and profiling tools - this 'HOWTO'
+            describes their basic usage and shows by example how to make use
+            of them to examine application and system behavior.
         </para>
 
         <para>
-            The Yocto Project Development Manual, however, does provide detailed examples
-            on how to change the kernel source code, reconfigure the kernel, and develop
-            an application using the popular <trademark class='trade'>Eclipse</trademark> IDE.
+            The tools presented are for the most part completely open-ended and
+            have quite good and/or extensive documentation of their own which
+            can be used to solve just about any problem you might come across
+            in Linux.
+            Each section that describes a particular tool has links to that
+            tool's documentation and website.

-        <title>What this Manual Provides</title>
+        <para>
+            The purpose of this 'HOWTO' is to present a set of common and
+            generally useful tracing and profiling idioms along with their
+            application (as appropriate) to each tool, in the context of a
+            general-purpose 'drill-down' methodology that can be applied
+            to solving a large number (90%?) of problems.
+            For help with more advanced usages and problems, please see
+            the documentation and/or websites listed for each tool.

+            Most of the tools are available only in 'sdk' images or in images
+            built after adding 'tools-profile' to your local.conf.
+            So, in order to be able to access all of the tools described here,
+            please first build and boot an 'sdk' image e.g.
+            <literallayout class='monospaced'>
+     $ bitbake core-image-sato-sdk
+            </literallayout>
+            or alternatively by adding 'tools-profile' to the
+            EXTRA_IMAGE_FEATURES line in your local.conf:
+            <literallayout class='monospaced'>
+      EXTRA_IMAGE_FEATURES = "debug-tweaks tools-profile"
+            </literallayout>
+            If you use the 'tools-profile' method, you don't need to build an
+            sdk image - the tracing and profiling tools will be included in
+            non-sdk images as well e.g.:
+            <literallayout class='monospaced'>
+     $ bitbake core-image-sato
+            </literallayout>
+            <note><para>
+                By default, the Yocto build system strips symbols from the
+                binaries it packages, which makes it difficult to use some
+                of the tools.
+                </para><para>You can prevent that by putting the following
+                in your local.conf when you build the image:
+                </para>
+            </note>
+            <literallayout class='monospaced'>
+     INHIBIT_PACKAGE_STRIP = "1"
+            </literallayout>
+            The above setting will noticeably increase the size of your image.
         </para>

-    <section id='other-information'>
-        <title>Other Information</title>
+        <para>
+            If you've already build a stripped image, you can generate
+            debug packages (xxx-dbg) which you can manually install as
+            needed.
