or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate

that such additional attribution notices cannot be construed
as modifying the License.
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.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. 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

## CouchRest - CouchDB, close to the metal == CouchRest - CouchDB, close to the metal
CouchRest is based on [CouchDB's couch.js test library](http://svn.apache.org/repos/asf/incubator/couchdb/trunk/share/www/script/couch.js), which I find to be concise, clear, and well designed. CouchRest lightly wraps CouchDB's HTTP API, managing JSON serialization, and remembering the URI-paths to CouchDB's API endpoints so you don't have to.

The core of Couchrest is Herokus excellent REST Client Ruby HTTP wrapper.
