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. * * END OF TERMS AND CONDITIONS * * APPENDIX: How to apply the Apache License to your work. * * 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.
