-Leveled execution logs for Go.
-
-This is an efficient pure Go implementation of leveled logs in the
-manner of the open source C++ package
-	http://code.google.com/p/google-glog
-
-By binding methods to booleans it is possible to use the log package
-without paying the expense of evaluating the arguments to the log.
-Through the -vmodule flag, the package also provides fine-grained
-control over logging at the file level.
-
-The comment from glog.go introduces the ideas:
-
-	Package glog implements logging analogous to the Google-internal
-	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
-	Error, Fatal, plus formatting variants such as Infof. It
-	also provides V-style logging controlled by the -v and
-	-vmodule=file=2 flags.
-	
-	Basic examples:
-	
-		glog.Info("Prepare to repel boarders")
-	
-		glog.Fatalf("Initialization failed: %s", err)
-	
-	See the documentation for the V function for an explanation
-	of these examples:
-	
-		if glog.V(2) {
-			glog.Info("Starting transaction...")
-		}
-	
-		glog.V(2).Infoln("Processed", nItems, "elements")
-
-
-The repository contains an open source version of the log package
-used inside Google. The master copy of the source lives inside
-Google, not here. The code in this repo is for export only and is not itself
-under development. Feature requests will be ignored.
-
-Send bug reports to [email protected].

-Package context stores values shared during a request lifetime.
-
-For example, a router can set variables extracted from the URL and later
-application handlers can access those values, or it can be used to store
-sessions values to be saved at the end of a request. There are several
-others common uses.
-
-The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
-
-	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
-
-Here's the basic usage: first define the keys that you will need. The key
-type is interface{} so a key can be of any type that supports equality.
-Here we define a key using a custom int type to avoid name collisions:
-
-	package foo
-
-	import (
-		"github.com/gorilla/context"
-	)
-
-	type key int
-
-	const MyKey key = 0
-
-Then set a variable. Variables are bound to an http.Request object, so you
-need a request instance to set a value:
-
-	context.Set(r, MyKey, "bar")
-
-The application can later access the variable using the same key you provided:
-
-	func MyHandler(w http.ResponseWriter, r *http.Request) {
-		// val is "bar".
-		val := context.Get(r, foo.MyKey)
-
-		// returns ("bar", true)
-		val, ok := context.GetOk(r, foo.MyKey)
-		// ...
-	}
-
-And that's all about the basic usage. We discuss some other ideas below.
-
-Any type can be stored in the context. To enforce a given type, make the key
-private and wrap Get() and Set() to accept and return values of a specific
-type:
-
-	type key int
-
-	const mykey key = 0
-
-	// GetMyKey returns a value for this package from the request values.
-	func GetMyKey(r *http.Request) SomeType {
-		if rv := context.Get(r, mykey); rv != nil {
-			return rv.(SomeType)
-		}
-		return nil
-	}
-
-	// SetMyKey sets a value for this package in the request values.
-	func SetMyKey(r *http.Request, val SomeType) {
-		context.Set(r, mykey, val)
-	}
-
-Variables must be cleared at the end of a request, to remove all values
-that were stored. This can be done in an http.Handler, after a request was
-served. Just call Clear() passing the request:
-
-	context.Clear(r)
-
-...or use ClearHandler(), which conveniently wraps an http.Handler to clear
-variables at the end of a request lifetime.
-
-The Routers from the packages gorilla/mux and gorilla/pat call Clear()
-so if you are using either of them you don't need to clear the context manually.

-Package gorilla/mux implements a request router and dispatcher.
-
-The name mux stands for "HTTP request multiplexer". Like the standard
-http.ServeMux, mux.Router matches incoming requests against a list of
-registered routes and calls a handler for the route that matches the URL
-or other conditions. The main features are:
-
-	* Requests can be matched based on URL host, path, path prefix, schemes,
-	  header and query values, HTTP methods or using custom matchers.
-	* URL hosts and paths can have variables with an optional regular
-	  expression.
-	* Registered URLs can be built, or "reversed", which helps maintaining
-	  references to resources.
-	* Routes can be used as subrouters: nested routes are only tested if the
-	  parent route matches. This is useful to define groups of routes that
-	  share common conditions like a host, a path prefix or other repeated
-	  attributes. As a bonus, this optimizes request matching.
-	* It implements the http.Handler interface so it is compatible with the
-	  standard http.ServeMux.
-
-Let's start registering a couple of URL paths and handlers:
-
-	func main() {
-		r := mux.NewRouter()
-		r.HandleFunc("/", HomeHandler)
-		r.HandleFunc("/products", ProductsHandler)
-		r.HandleFunc("/articles", ArticlesHandler)
-		http.Handle("/", r)
-	}
-
-Here we register three routes mapping URL paths to handlers. This is
-equivalent to how http.HandleFunc() works: if an incoming request URL matches
-one of the paths, the corresponding handler is called passing
-(http.ResponseWriter, *http.Request) as parameters.
-
-Paths can have variables. They are defined using the format {name} or
-{name:pattern}. If a regular expression pattern is not defined, the matched
-variable will be anything until the next slash. For example:
-
-	r := mux.NewRouter()
-	r.HandleFunc("/products/{key}", ProductHandler)
-	r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
-	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
-
-The names are used to create a map of route variables which can be retrieved
-calling mux.Vars():
-
-	vars := mux.Vars(request)
-	category := vars["category"]
-
-And this is all you need to know about the basic usage. More advanced options
-are explained below.
-
-Routes can also be restricted to a domain or subdomain. Just define a host
-pattern to be matched. They can also have variables:
-
-	r := mux.NewRouter()
-	// Only matches if domain is "www.domain.com".
-	r.Host("www.domain.com")
-	// Matches a dynamic subdomain.
-	r.Host("{subdomain:[a-z]+}.domain.com")
-
-There are several other matchers that can be added. To match path prefixes:
-
-	r.PathPrefix("/products/")
-
-...or HTTP methods:
-
-	r.Methods("GET", "POST")
-
-...or URL schemes:
-
-	r.Schemes("https")
-
-...or header values:
-
-	r.Headers("X-Requested-With", "XMLHttpRequest")
-
-...or query values:
-
-	r.Queries("key", "value")
-
-...or to use a custom matcher function:
-
-	r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
-		return r.ProtoMajor == 0
-	})
-
-...and finally, it is possible to combine several matchers in a single route:
-
-	r.HandleFunc("/products", ProductsHandler).
-	  Host("www.domain.com").
-	  Methods("GET").
-	  Schemes("http")
-
-Setting the same matching conditions again and again can be boring, so we have
-a way to group several routes that share the same requirements.
-We call it "subrouting".
-
-For example, let's say we have several URLs that should only match when the
-host is "www.domain.com". Create a route for that host and get a "subrouter"
-from it:
-
-	r := mux.NewRouter()
-	s := r.Host("www.domain.com").Subrouter()
-
-Then register routes in the subrouter:
-
-	s.HandleFunc("/products/", ProductsHandler)
-	s.HandleFunc("/products/{key}", ProductHandler)
-	s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
-
-The three URL paths we registered above will only be tested if the domain is
-"www.domain.com", because the subrouter is tested first. This is not
-only convenient, but also optimizes request matching. You can create
-subrouters combining any attribute matchers accepted by a route.
-
-Subrouters can be used to create domain or path "namespaces": you define
-subrouters in a central place and then parts of the app can register its
-paths relatively to a given subrouter.
-
-There's one more thing about subroutes. When a subrouter has a path prefix,
-the inner routes use it as base for their paths:
-
-	r := mux.NewRouter()
-	s := r.PathPrefix("/products").Subrouter()
-	// "/products/"
-	s.HandleFunc("/", ProductsHandler)
-	// "/products/{key}/"
-	s.HandleFunc("/{key}/", ProductHandler)
-	// "/products/{key}/details"
-	s.HandleFunc("/{key}/details", ProductDetailsHandler)
-
-Now let's see how to build registered URLs.
-
-Routes can be named. All routes that define a name can have their URLs built,
-or "reversed". We define a name calling Name() on a route. For example:
-
-	r := mux.NewRouter()
-	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
-	  Name("article")
-
-To build a URL, get the route and call the URL() method, passing a sequence of
-key/value pairs for the route variables. For the previous route, we would do:
-
-	url, err := r.Get("article").URL("category", "technology", "id", "42")
-
-...and the result will be a url.URL with the following path:
-
-	"/articles/technology/42"
-
-This also works for host variables:
-
-	r := mux.NewRouter()
-	r.Host("{subdomain}.domain.com").
-	  Path("/articles/{category}/{id:[0-9]+}").
-	  HandlerFunc(ArticleHandler).
-	  Name("article")
-
-	// url.String() will be "http://news.domain.com/articles/technology/42"
-	url, err := r.Get("article").URL("subdomain", "news",
-	                                 "category", "technology",
-	                                 "id", "42")
-
-All variables defined in the route are required, and their values must
-conform to the corresponding patterns. These requirements guarantee that a
-generated URL will always match a registered route -- the only exception is
-for explicitly defined "build-only" routes which never match.
-
-There's also a way to build only the URL host or path for a route:
-use the methods URLHost() or URLPath() instead. For the previous route,
-we would do:
-
-	// "http://news.domain.com/"
-	host, err := r.Get("article").URLHost("subdomain", "news")
-
-	// "/articles/technology/42"
-	path, err := r.Get("article").URLPath("category", "technology", "id", "42")
-
-And if you use subrouters, host and path defined separately can be built
-as well:
-
-	r := mux.NewRouter()
-	s := r.Host("{subdomain}.domain.com").Subrouter()
-	s.Path("/articles/{category}/{id:[0-9]+}").
-	  HandlerFunc(ArticleHandler).
-	  Name("article")
-
-	// "http://news.domain.com/articles/technology/42"
-	url, err := r.Get("article").URL("subdomain", "news",
-	                                 "category", "technology",
-	                                 "id", "42")

-# Gorilla WebSocket
-
-Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
-[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.
-
-### Documentation
-
-* [API Reference](http://godoc.org/github.com/gorilla/websocket)
-* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
-* [File watch example](https://github.com/gorilla/websocket/tree/master/examples/filewatch)
-
-### Status
-
-The Gorilla WebSocket package provides a complete and tested implementation of
-the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
-package API is stable.
-
-### Installation
-
-    go get github.com/gorilla/websocket
-
-### Protocol Compliance
-
-The Gorilla WebSocket package passes the server tests in the [Autobahn Test
-Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
-subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).

-
-Notes: 
-
-1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
-2. The application can get the type of a received data message by implementing
-   a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
-   function.
-3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
-  Read returns when the input buffer is full or a frame boundary is
-  encountered. Each call to Write sends a single frame message. The Gorilla
-  io.Reader and io.WriteCloser operate on a single WebSocket message.

-// Package websocket implements the WebSocket protocol defined in RFC 6455.
-//
-// Overview
-//
-// The Conn type represents a WebSocket connection. A server application uses
-// the Upgrade function from an Upgrader object with a HTTP request handler
-// to get a pointer to a Conn:
-//
-//  var upgrader = websocket.Upgrader{
-//      ReadBufferSize:  1024,
-//      WriteBufferSize: 1024,
-//  }
-//
-//  func handler(w http.ResponseWriter, r *http.Request) {
-//      conn, err := upgrader.Upgrade(w, r, nil)
-//      if err != nil {
-//          log.Println(err)
-//          return
-//      }
-//      ... Use conn to send and receive messages.
-//  }
-//
-// Call the connection's WriteMessage and ReadMessage methods to send and
-// receive messages as a slice of bytes. This snippet of code shows how to echo
-// messages using these methods:
-//
-//  for {
-//      messageType, p, err := conn.ReadMessage()
-//      if err != nil {
-//          return
-//      }
-//      if err = conn.WriteMessage(messageType, p); err != nil {
-//          return err
-//      }
-//  }
-//
-// In above snippet of code, p is a []byte and messageType is an int with value
-// websocket.BinaryMessage or websocket.TextMessage.
-//
-// An application can also send and receive messages using the io.WriteCloser
-// and io.Reader interfaces. To send a message, call the connection NextWriter
-// method to get an io.WriteCloser, write the message to the writer and close
-// the writer when done. To receive a message, call the connection NextReader
-// method to get an io.Reader and read until io.EOF is returned. This snippet
-// snippet shows how to echo messages using the NextWriter and NextReader
-// methods:
-//
-//  for {
-//      messageType, r, err := conn.NextReader()
-//      if err != nil {
-//          return
-//      }
-//      w, err := conn.NextWriter(messageType)
-//      if err != nil {
-//          return err
-//      }
-//      if _, err := io.Copy(w, r); err != nil {
-//          return err
-//      }
-//      if err := w.Close(); err != nil {
-//          return err
-//      }
-//  }
-//
-// Data Messages
-//
-// The WebSocket protocol distinguishes between text and binary data messages.
-// Text messages are interpreted as UTF-8 encoded text. The interpretation of
-// binary messages is left to the application.
-//
-// This package uses the TextMessage and BinaryMessage integer constants to
-// identify the two data message types. The ReadMessage and NextReader methods
-// return the type of the received message. The messageType argument to the
-// WriteMessage and NextWriter methods specifies the type of a sent message.
-//
-// It is the application's responsibility to ensure that text messages are
-// valid UTF-8 encoded text.
-//
-// Control Messages
-//
-// The WebSocket protocol defines three types of control messages: close, ping
-// and pong. Call the connection WriteControl, WriteMessage or NextWriter
-// methods to send a control message to the peer.
-//
-// Connections handle received ping and pong messages by invoking a callback
-// function set with SetPingHandler and SetPongHandler methods. These callback
-// functions can be invoked from the ReadMessage method, the NextReader method
-// or from a call to the data message reader returned from NextReader.
-//
-// Connections handle received close messages by returning an error from the
-// ReadMessage method, the NextReader method or from a call to the data message
-// reader returned from NextReader.
-//
-// Concurrency
-//
-// Connections do not support concurrent calls to the write methods
-// (NextWriter, SetWriteDeadline, WriteMessage) or concurrent calls to the read
-// methods methods (NextReader, SetReadDeadline, ReadMessage).  Connections do
-// support a concurrent reader and writer.
-//
-// The Close and WriteControl methods can be called concurrently with all other
-// methods.
-//
-// Read is Required
-//
-// The application must read the connection to process ping and close messages
-// sent from the peer. If the application is not otherwise interested in
-// messages from the peer, then the application should start a goroutine to read
-// and discard messages from the peer. A simple example is:
-//
-//  func readLoop(c *websocket.Conn) {
-//      for {
-//          if _, _, err := c.NextReader(); err != nil {
-//              c.Close()
-//              break
-//          }
-//      }
-//  }
-//
-// Origin Considerations
-//
-// Web browsers allow Javascript applications to open a WebSocket connection to
-// any host. It's up to the server to enforce an origin policy using the Origin
-// request header sent by the browser.
-//
-// The Upgrader calls the function specified in the CheckOrigin field to check
-// the origin. If the CheckOrigin function returns false, then the Upgrade
-// method fails the WebSocket handshake with HTTP status 403.
-//
-// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail
-// the handshake if the Origin request header is present and not equal to the
-// Host request header.
-//
-// An application can allow connections from any origin by specifying a
-// function that always returns true:
-//
-//    var upgrader = websocket.Upgrader{
-//      CheckOrigin: func(r *http.Request) bool { return true },
-//   }
-//
-// The deprecated Upgrade function does not enforce an origin policy. It's the
-// application's responsibility to check the Origin header before calling
-// Upgrade.

-# Chat Example
-
-This application shows how to use use the
-[websocket](https://github.com/gorilla/websocket) package and
-[jQuery](http://jquery.com) to implement a simple web chat application.
-
-## Running the example
-
-The example requires a working Go development environment. The [Getting
-Started](http://golang.org/doc/install) page describes how to install the
-development environment.
-
-Once you have Go up and running, you can download, build and run the example
-using the following commands.
-
-    $ go get github.com/gorilla/websocket
-    $ cd `go list -f '{{.Dir}}' github.com/gorilla/websocket/examples/chat`
-    $ go run *.go
