-    <title>Application Development Using the Yocto Project</title>
-    <para>
-        The Yocto Project supports several methods of application development through which 
-        you can create user-space software designed to run on an embedded device that uses
-        a Yocto Project image, which was developed with the OpenEmbedded build system. 
-        This flexibility allows you to choose the method that works best for you.  
-        This chapter describes each development method.

-        <title>Development Within Yocto Project for a Package that Uses an External SCM</title>
-
-        <para>
-            If you're working on a recipe that pulls from an external Source Code Manager (SCM), it 
-            is possible to have the OpenEmbedded build system notice new changes added to the 
-            SCM and then build the package that depends on them using the latest version. 
-            This only works for SCMs from which it is possible to get a sensible revision number for changes.
-            Currently, you can do this with Apache Subversion (SVN), Git, and Bazaar (BZR) repositories.

-        <para>
-            To enable this behavior, simply add the following to the <filename>local.conf</filename>
-            configuration file found in the 
-            <ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>build directory</ulink>:
-            <literallayout class='monospaced'>
-     SRCREV_pn-&lt;PN&gt; = "${AUTOREV}"
-            </literallayout>
-            where <filename>PN</filename> 
-            is the name of the package for which you want to enable automatic source 
-            revision updating.
