-        The Yocto Project presents the kernel as a fully patched, history-clean git
-        repository. 
-        The git tree represents the selected features, board support,
-        and configurations extensively tested by Yocto Project. 
-        The Yocto Project kernel allows the end user to leverage community
-        best practices to seamlessly manage the development, build and debug cycles.
+        Recall that earlier we talked about how to use an existing toolchain 
+        tarball that had been installed into <filename>/opt/poky</filename>, 
+        which is outside of the Poky build environment 
+        (see <xref linkend='using-an-existing-toolchain-tarball'>
+        “Using an Existing Toolchain Tarball”)</xref>.  
+        And, that sourcing your architecture-specific environment setup script 
+        initializes a suitable development environment.  
+        This setup occurs by adding the compiler, QEMU scripts, QEMU binary, 
+        a special version of <filename>pkgconfig</filename> and other useful 
+        utilities to the <filename>PATH</filename> variable.
+        Variables to assist pkgconfig and autotools are also defined so that, 
+        for example, <filename>configure.sh</filename> can find pre-generated 
+        test results for tests that need target hardware on which to run.  
+        These conditions allow you to easily use the toolchain outside of the 
+        Poky build environment on both autotools-based projects and 
+        makefile-based projects.

-        This manual describes the Yocto Project kernel by providing information
-        on its history, organization, benefits, and use.
-        The manual consists of two sections:
-        <itemizedlist>
-            <listitem><para>Concepts - Describes concepts behind the kernel.
-                You will understand how the kernel is organized and why it is organized in 
-                the way it is.  You will understand the benefits of the kernel's organization 
-                and the mechanisms used to work with the kernel and how to apply it in your 
-                design process.</para></listitem>
-            <listitem><para>Using the Kernel - Describes best practices and "how-to" information
-                that lets you put the kernel to practical use.  Some examples are "How to Build a 
-                Project Specific Tree", "How to Examine Changes in a Branch", and "Saving Kernel
-                Modifications."</para></listitem>
-        </itemizedlist>
+        For an autotools-based project you can use the cross-toolchain by just 
+        passing the appropriate host option to <filename>configure.sh</filename>.
+        The host option you use is derived from the name of the environment setup 
+        script in <filename>/opt/poky</filename> resulting from unpacking the 
+        cross-toolchain tarball.
+        For example, the host option for an ARM-based target that uses the GNU EABI 
+        is <filename>armv5te-poky-linux-gnueabi</filename>.
+        Note that the name of the script is 
+        <filename>environment-setup-armv5te-poky-linux-gnueabi</filename>.
+        Thus, the following command works:
+        <literallayout class='monospaced'>
+     $ configure &dash;&dash;host-armv5te-poky-linux-gnueabi &dash;&dash;with-libtool-sysroot=&lt;sysroot-dir&gt;
+        </literallayout>
     </para>

+    <para>
+        For a makefile-based project you use the cross-toolchain by making sure 
+        the tools are used.  
+        You can do this as follows:
+        <literallayout class='monospaced'>
+     CC=arm-poky-linux-gnueabi-gcc
+     LD=arm-poky-linux-gnueabi-ld
+     CFLAGS=”${CFLAGS} &dash;&dash;sysroot=&lt;sysroot-dir&gt;”
+     CXXFLAGS=”${CXXFLAGS} &dash;&dash;sysroot=&lt;sysroot-dir&gt;”
+        </literallayout>
