+JSGI 0.3 Adapter for Node
+
+To use provide a JSGI application (can be application stack) to the start 
+function:
+
+require("jsgi-node").start(function(request){
+    var requestBody = request.input.read().decodeToString("UTF-8");
+    return {
+        status:200,
+        headers:{},
+        body:["echo: " + requestBody]
+    };
+});
+
+This adapter should conform to the JSGI 0.3 (with promises) for full 
+asynchronous support. For example:
+
+var posix = require("posix");
+require("jsgi-node").start(function(request){
+   var promise = new process.Promise();
+   posix.cat("jsgi-node.js").addCallback(function(body){
+       promise.emitSuccess({
+	       status: 200,
+		   headers: {},
+		   body: [body]
+	   });
+   });
+   return promise;
+});
