-=====
-
-Clock is a small library for mocking time in Go. It provides an interface
-around the standard library's [`time`][time] package so that the application
-can use the realtime clock while tests can use the mock clock.
-
-[time]: http://golang.org/pkg/time/
-
-
-## Usage
-
-### Realtime Clock
-
-Your application can maintain a `Clock` variable that will allow realtime and
-mock clocks to be interchangable. For example, if you had an `Application` type:
-
-```go
-import "github.com/benbjohnson/clock"
-
-type Application struct {
- Clock clock.Clock
-}
-```
-
-You could initialize it to use the realtime clock like this:
-
-```go
-var app Application
-app.Clock = clock.New()
-...
-```
-
-Then all timers and time-related functionality should be performed from the
-`Clock` variable.
-
-
-### Mocking time
-
-In your tests, you will want to use a `Mock` clock:
-
-```go
-import (
- "testing"
-
- "github.com/benbjohnson/clock"
-)
-
-func TestApplication_DoSomething(t *testing.T) {
- mock := clock.NewMock()
- app := Application{Clock: mock}
- ...
-}
-```
-
-Now that you've initialized your application to use the mock clock, you can
-adjust the time programmatically. The mock clock always starts from the Unix
-epoch (midnight, Jan 1, 1970 UTC).
-
-
-### Controlling time
-
-The mock clock provides the same functions that the standard library's `time`
-package provides. For example, to find the current time, you use the `Now()`
-function:
-
-```go
-mock := clock.NewMock()
-
-// Find the current time.
-mock.Now().UTC() // 1970-01-01 00:00:00 +0000 UTC
-
-// Move the clock forward.
-mock.Add(2 * time.Hour)
-
-// Check the time again. It's 2 hours later!
-mock.Now().UTC() // 1970-01-01 02:00:00 +0000 UTC
-```
-
-Timers and Tickers are also controlled by this same mock clock. They will only
-execute when the clock is moved forward:
-
-```
-mock := clock.NewMock()
-count := 0
-
-// Kick off a timer to increment every 1 mock second.
-go func() {
- ticker := clock.Ticker(1 * time.Second)
- for {
- <-ticker.C
- count++
- }
-}()
-runtime.Gosched()
-
-// Move the clock forward 10 second.
-mock.Add(10 * time.Second)
-
-// This prints 10.
-fmt.Println(count)
-```
-

-httpdown [![Build Status](https://secure.travis-ci.org/facebookgo/httpdown.png)](https://travis-ci.org/facebookgo/httpdown)
-========
-
-Documentation: https://godoc.org/github.com/facebookgo/httpdown
-
-Package httpdown provides a library that makes it easy to build a HTTP server
-that can be shutdown gracefully (that is, without dropping any connections).
-
-If you want graceful restart and not just graceful shutdown, look at the
-[grace](https://github.com/facebookgo/grace) package which uses this package
-underneath but also provides graceful restart.
-
-Usage
------
-
-Demo HTTP Server with graceful termination:
-https://github.com/facebookgo/httpdown/blob/master/httpdown_example/main.go
-
-1. Install the demo application
-
- go get github.com/facebookgo/httpdown/httpdown_example
-
-1. Start it in the first terminal
-
- httpdown_example
-
- This will output something like:
-
- 2014/11/18 21:57:50 serving on http://127.0.0.1:8080/ with pid 17
-
-1. In a second terminal start a slow HTTP request
-
- curl 'http://localhost:8080/?duration=20s'
-
-1. In a third terminal trigger a graceful shutdown (using the pid from your output):
-
- kill -TERM 17
-
-This will demonstrate that the slow request was served before the server was
-shutdown. You could also have used `Ctrl-C` instead of `kill` as the example
-application triggers graceful shutdown on TERM or INT signals.
