-Package context stores values shared during a request lifetime.
-
-Note: gorilla/context, having been born well before `context.Context` existed,
-does not play well > with the shallow copying of the request that
-[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
-(added to net/http Go 1.7 onwards) performs. You should either use *just*
-gorilla/context, or moving forward, the new `http.Request.Context()`.
-
-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.
