+                Yes - you can easily do this.
+                When you use BitBake to build an image, all the build output goes into the 
+                directory created when you source the <filename>oe-init-build-env</filename>
+                setup file.
+                By default, this <ulink url='&YOCTO_DOCS_DEV_URL;#yocto-project-build-directory'>Yocto
+                Project Build Directory</ulink> is named <filename>build</filename> but can be named
+                anything you want.

+                Within the Yocto Project Build Directory is the <filename>tmp</filename>
+                directory. 
+                To remove all the build output yet preserve any source code or downloaded files
+                from previous builds, simply remove the <filename>tmp</filename> directory.
