 		     END OF TERMS AND CONDITIONS
 
-	    How to Apply These Terms to Your New Programs
+Note:
+Individual files contain the following tag instead of the full license text.
 
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
+    SPDX-License-Identifier: GPL-2.0-only
 
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

+                intent of the change.
+                In particular, when you append a value to a variable that
+                has a default value, the resulting value might not be what
+                you expect.
+                In this case, the value you provide might replace the value
+                rather than append to the default value.
+            </para>
+
+            <para>
+                If after you have changed a variable's value and something
+                unexplained occurs, you can use BitBake to check the actual
+                value of the suspect variable.
+                You can make these checks for both configuration and recipe
+                level changes:
+                <itemizedlist>
+                    <listitem><para>
+                        For configuration changes, use the following:
+                        <literallayout class='monospaced'>
+     $ bitbake -e
+                        </literallayout>
+                        This command displays variable values after the
+                        configuration files (i.e. <filename>local.conf</filename>,
+                        <filename>bblayers.conf</filename>,
+                        <filename>bitbake.conf</filename> and so forth) have
+                        been parsed.
+                        <note>
+                            Variables that are exported to the environment are
+                            preceded by the string "export" in the command's
+                            output.
+                        </note>
+                        </para></listitem>
+                    <listitem><para>
+                        For recipe changes, use the following:
+                        <literallayout class='monospaced'>
+     $ bitbake <replaceable>recipe</replaceable> -e | grep VARIABLE="
+                        </literallayout>
+                        This command checks to see if the variable actually
+                        makes it into a specific recipe.
+                        </para></listitem>
