However, in accepting such obligations, You may act only&#xA;   on Your own behalf and on Your sole responsibility, not on behalf&#xA;   of any other Contributor, and only if You agree to indemnify,&#xA;   defend, and hold each Contributor harmless for any liability&#xA;   incurred by, or claims asserted against, such Contributor by reason&#xA;   of your accepting any such warranty or additional liability.&#xA;&#xA;END OF TERMS AND CONDITIONS&#xA;&#xA;APPENDIX: How to apply the Apache License to your work.&#xA;&#xA;   To apply the Apache License to your work, attach the following&#xA;   boilerplate notice, with the fields enclosed by brackets &#34;[]&#34;&#xA;   replaced with your own identifying information.
