-
-Like many open source projects, we need a contributor license agreement
-from you before we can merge in your changes.
-
-In summary, by submitting your code, you are granting us a right to use
-that code under the terms of this Agreement, including providing it to
-others. You are also certifying that you wrote it, and that you are
-allowed to license it to us. You are not giving up your copyright in
-your work. The license does not change your rights to use your own
-contributions for any other purpose.
-
-Contributor License Agreements are important because they define the
-chain of ownership of a piece of software. Some companies won't allow
-the use of free software without clear agreements around code ownership.
-That's why many open source projects collect similar agreements from
-contributors. The CLA here is based on the Apache CLA.
-
-To signify your agreement to these terms, add the following line to the
-bottom of your commit message. Use your real name and an actual e-mail
-address.

-Alternatively you can use the git command line to automatically add this
