The contents * of the NOTICE file are for informational purposes only and * do not modify the License. You may add Your own attribution * notices within Derivative Works that You distribute, alongside * or as an addendum to the NOTICE text from the Work, provided * that such additional attribution notices cannot be construed * as modifying the License. * <p/> * You may add Your own copyright statement to Your modifications and * may provide additional or different license terms and conditions * for use, reproduction, or distribution of Your modifications, or * for any such Derivative Works as a whole, provided Your use, * reproduction, and distribution of the Work otherwise complies with * the conditions stated in this License. * <p/> * 5.

Accepting Warranty or Additional Liability. While redistributing * the Work or Derivative Works thereof, You may choose to offer, * and charge a fee for, acceptance of support, warranty, indemnity, * or other liability obligations and/or rights consistent with this * License. However, in accepting such obligations, You may act only * on Your own behalf and on Your sole responsibility, not on behalf * of any other Contributor, and only if You agree to indemnify, * defend, and hold each Contributor harmless for any liability * incurred by, or claims asserted against, such Contributor by reason * of your accepting any such warranty or additional liability. * <p/> * END OF TERMS AND CONDITIONS * <p/> * APPENDIX: How to apply the Apache License to your work. * <p/> * To apply the Apache License to your work, attach the following * boilerplate notice, with the fields enclosed by brackets "{}" * replaced with your own identifying information.
