+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/toml-lang/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.

-/*
-Package restful , a lean package for creating REST-style WebServices without magic.
-
-WebServices and Routes
-
-A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
-Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
-WebServices must be added to a container (see below) in order to handler Http requests from a server.
-
-A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
-This package has the logic to find the best matching Route and if found, call its Function.
-
-	ws := new(restful.WebService)
-	ws.
-		Path("/users").
-		Consumes(restful.MIME_JSON, restful.MIME_XML).
-		Produces(restful.MIME_JSON, restful.MIME_XML)
-
-	ws.Route(ws.GET("/{user-id}").To(u.findUser))  // u is a UserResource
-
-	...
-
-	// GET http://localhost:8080/users/1
-	func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
-		id := request.PathParameter("user-id")
-		...
-	}
-
-The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
-
-See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
-
-Regular expression matching Routes
-
-A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
-For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
-Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
-This feature requires the use of a CurlyRouter.
-
-Containers
-
-A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
-Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
-The Default container of go-restful uses the http.DefaultServeMux.
-You can create your own Container and create a new http.Server for that particular container.
-
-	container := restful.NewContainer()
-	server := &http.Server{Addr: ":8081", Handler: container}
-
-Filters
-
-A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
-You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
-In the restful package there are three hooks into the request,response flow where filters can be added.
-Each filter must define a FilterFunction:
-
-	func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
-
-Use the following statement to pass the request,response pair to the next filter or RouteFunction
-
-	chain.ProcessFilter(req, resp)
-
-Container Filters
-
-These are processed before any registered WebService.
-
-	// install a (global) filter for the default container (processed before any webservice)
-	restful.Filter(globalLogging)
-
-WebService Filters
-
-These are processed before any Route of a WebService.
-
-	// install a webservice filter (processed before any route)
-	ws.Filter(webserviceLogging).Filter(measureTime)
-
-
-Route Filters
-
-These are processed before calling the function associated with the Route.
-
-	// install 2 chained route filters (processed before calling findUser)
-	ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
-
-See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
-
-Response Encoding
-
-Two encodings are supported: gzip and deflate. To enable this for all responses:
-
-	restful.DefaultContainer.EnableContentEncoding(true)
-
-If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
-Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
-
-See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
-
-OPTIONS support
-
-By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
-
-	Filter(OPTIONSFilter())
-
-CORS
-
-By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
-
-	cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
-	Filter(cors.Filter)
-
-Error Handling
-
-Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
-For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
-
-	400: Bad Request
-
-If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
-
-	404: Not Found
-
-Despite a valid URI, the resource requested may not be available
-
-	500: Internal Server Error
-
-If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
-
-	405: Method Not Allowed
-
-The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
-
-	406: Not Acceptable
-
-The request does not have or has an unknown Accept Header set for this operation.
-
-	415: Unsupported Media Type
-
-The request does not have or has an unknown Content-Type Header set for this operation.
-
-ServiceError
-
-In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
-
-Performance options
-
-This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
-
-	restful.DefaultContainer.DoNotRecover(false)
-
-DoNotRecover controls whether panics will be caught to return HTTP 500.
-If set to false, the container will recover from panics.
-Default value is true
-
-	restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
-
-If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
-Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
-
-Trouble shooting
-
-This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
-Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
-
-	restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
-
-Logging
-
-The restful.SetLogger() method allows you to override the logger used by the package. By default restful
-uses the standard library `log` package and logs to stdout. Different logging packages are supported as
-long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
-preferred package is simple.
