Apache License, Version 2.0

The 2.0 version of the Apache License, approved by the ASF in 2004, helps us achieve our goal of providing reliable and long-lived software products through collaborative, open-source software development.

All packages produced by the ASF are implicitly licensed under the Apache License, Version 2.0, unless otherwise explicitly stated.

How to apply the Apache License to your work

Include a copy of the Apache License, typically in a file called LICENSE, in your work, and consider also including a NOTICE file that references the License.

To apply the Apache License to specific files in your work, attach the following boilerplate declaration, replacing the fields enclosed by brackets “[]” with your own identifying information. (Don't include the brackets!) Enclose the text in the appropriate comment syntax for the file format. We also recommend that you include a file or class name and description of purpose on the same “printed page” as the copyright notice for easier identification within third-party archives.
