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.
CouchRest's lighweight is designed to make a simple base for application and framework-specific object oriented APIs.
The core of Couchrest is Heroku’s excellent REST Client Ruby HTTP wrapper. REST Client takes all the nastyness of Net::HTTP and gives is a pretty face, while still giving you more control than Open-URI. I recommend it anytime you’re interfacing with a well-defined web service.
The most complete documentation is the spec/ directory. To validate your CouchRest install, from the project root directory run `rake`, or `autotest` (requires RSpec and optionally ZenTest for autotest support).
