+==========
+
+package for building REST-style Web Services using Google Go
+
+REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
+
+- GET = Retrieve a representation of a resource
+- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
+- PUT = Create if you are sending the full content of the specified resource (URI).
+- PUT = Update if you are updating the full content of the specified resource.
+- DELETE = Delete if you are requesting the server to delete the resource
+- PATCH = Update partial content of a resource
+- OPTIONS = Get information about the communication options for the request URI
+    
+### Example
+
+```Go
+ws := new(restful.WebService)
+ws.
+	Path("/users").
+	Consumes(restful.MIME_XML, restful.MIME_JSON).
+	Produces(restful.MIME_JSON, restful.MIME_XML)
+
+ws.Route(ws.GET("/{user-id}").To(u.findUser).
+	Doc("get a user").
+	Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
+	Writes(User{}))		
+...
+	
+func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+	id := request.PathParameter("user-id")
+	...
+}
+```
+

+		
+### Features
+
+- Routes for request → function mapping with path parameter (e.g. {id}) support
+- Configurable router:
+	- Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions (See RouterJSR311 which is used by default)
+	- Fast routing algorithm that allows static elements, regular expressions and dynamic parameters in the URL path (e.g. /meetings/{id} or /static/{subpath:*}, See CurlyRouter)
+- Request API for reading structs from JSON/XML and accesing parameters (path,query,header)
+- Response API for writing structs to JSON/XML and setting headers
+- Filters for intercepting the request → response flow on Service or Route level
+- Request-scoped variables using attributes
+- Containers for WebServices on different HTTP endpoints
+- Content encoding (gzip,deflate) of request and response payloads
+- Automatic responses on OPTIONS (using a filter)
+- Automatic CORS request handling (using a filter)
+- API declaration for Swagger UI (see swagger package)
+- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
+- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
+- Configurable (trace) logging
+- Customizable encoding using EntityReaderWriter registration
+- Customizable gzip/deflate readers and writers using CompressorProvider registration
