Trademarks. This License does not grant permission to use the trade+      names, trademarks, service marks, or product names of the Licensor,+      except as required for reasonable and customary use in describing the+      origin of the Work and reproducing the content of the NOTICE file.++   7.

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.
