CONDUCT.md

@@ -1,92 +0,0 @@
-## Conduct
-
-* We are committed to providing a friendly, safe and welcoming
-  environment for all, regardless of gender, sexual orientation,
-  disability, ethnicity, religion, or similar personal characteristic.
-
-* On IRC, please avoid using overtly sexual nicknames or other nicknames
-  that might detract from a friendly, safe and welcoming environment for
-  all.
-
-* Please be kind and courteous. There's no need to be mean or rude.
-
-* Respect that people have differences of opinion and that every design
-  or implementation choice carries a trade-off and numerous costs. There
-  is seldom a right answer.
-
-* Please keep unstructured critique to a minimum. If you have solid
-  ideas you want to experiment with, make a fork and see how it works.
-
-* We will exclude you from interaction if you insult, demean or harass
-  anyone. That is not welcome behaviour. We interpret the term
-  "harassment" as including the definition in the <a
-  href="http://citizencodeofconduct.org/">Citizen Code of Conduct</a>;
-  if you have any lack of clarity about what might be included in that
-  concept, please read their definition. In particular, we don't
-  tolerate behavior that excludes people in socially marginalized
-  groups.
-
-* Private harassment is also unacceptable. No matter who you are, if you
-  feel you have been or are being harassed or made uncomfortable by a
-  community member, please contact one of the channel ops or any of the
-  Syncthing core team immediately. Whether you're a regular  contributor
-  or a newcomer, we care about making this community a safe place for
-  you and we've got your back.
-
-* Likewise any spamming, trolling, flaming, baiting or other
-  attention-stealing behaviour is not welcome.
-
-## Moderation
-
-These are the policies for upholding our community's standards of
-conduct in our communication channels, most notably in Syncthing-related
-IRC channels and on the web forum.
-
-1. Remarks that violate the Syncthing standards of conduct, including
-   hateful, hurtful, oppressive, or exclusionary remarks, are not
-   allowed. (Cursing is allowed, but never targeting another user, and
-   never in a hateful manner.)
-
-2. Remarks that moderators find inappropriate, whether listed in the
-   code of conduct or not, are also not allowed.
-
-3. Moderators will first respond to such remarks with a warning.
-
-4. If the warning is unheeded, the user will be "kicked," i.e., kicked
-   out of the communication channel to cool off.
-
-5. If the user comes back and continues to make trouble, they will be
-   banned, i.e., indefinitely excluded.
-
-6. Moderators may choose at their discretion to un-ban the user if it
-   was a first offense and they offer the offended party a genuine
-   apology.
-
-7. If a moderator bans someone and you think it was unjustified, please
-   take it up with that moderator, or with a different moderator, **in
-   private**. Complaints about bans in-channel are not allowed.
-
-8. Moderators are held to a higher standard than other community
-   members. If a moderator creates an inappropriate situation, they
-   should expect less leeway than others.
-
-In the Syncthing community we strive to go the extra step to look out
-for each other. Don't just aim to be technically unimpeachable, try to
-be your best self. In particular, avoid flirting with offensive or
-sensitive issues, particularly if they're off-topic; this all too
-often leads to unnecessary fights, hurt feelings, and damaged trust;
-worse, it can drive people away from the community entirely.
-
-And if someone takes issue with something you said or did, resist the
-urge to be defensive. Just stop doing what it was they complained about
-and apologize. Even if you feel you were misinterpreted or unfairly
-accused, chances are good there was something you could've communicated
-better — remember that it's your responsibility to make your fellow
-community members comfortable. Everyone wants to get along and we are
-all here first and foremost because we want to talk about cool
-technology. You will find that people will be eager to assume good
-intent and forgive as long as you earn their trust.

-## Reporting Bugs
-
-Please file bugs in the [Github Issue
-Tracker](https://github.com/syncthing/syncthing/issues). Include at
-least the following:
-
- - What happened
-
- - What did you expect to happen instead of what *did* happen, if it's
-   not crazy obvious
-
- - What operating system, operating system version and version of
-   Syncthing you are running
-
- - The same for other connected devices, where relevant
-
- - Screenshot if the issue concerns something visible in the GUI
-
- - Console log entries, where possible and relevant
-
-If you're not sure whether something is relevant, erring on the side of
-too much information will never get you yelled at. :)

-go-lz4
-======
-
-go-lz4 is port of LZ4 lossless compression algorithm to Go. The original C code
-is located at:
-
-https://github.com/Cyan4973/lz4
-
-Status
-------
-[![Build Status](https://secure.travis-ci.org/bkaradzic/go-lz4.png)](http://travis-ci.org/bkaradzic/go-lz4)  
-[![GoDoc](https://godoc.org/github.com/bkaradzic/go-lz4?status.png)](https://godoc.org/github.com/bkaradzic/go-lz4)
-
-Usage
------
-
-    go get github.com/bkaradzic/go-lz4
-
-    import "github.com/bkaradzic/go-lz4"
-
-The package name is `lz4`
-
-Notes
------
-
-* go-lz4 saves a uint32 with the original uncompressed length at the beginning
-  of the encoded buffer.  They may get in the way of interoperability with
-  other implementations.

-admirably balanced mind. He was, I take it, the most perfect
-reasoning and observing machine that the world has seen, but as a
-lover he would have placed himself in a false position. He never
-spoke of the softer passions, save with a gibe and a sneer. They
-were admirable things for the observer--excellent for drawing the
-veil from men's motives and actions. But for the trained reasoner
-to admit such intrusions into his own delicate and finely
-adjusted temperament was to introduce a distracting factor which
-might throw a doubt upon all his mental results. Grit in a
-sensitive instrument, or a crack in one of his own high-power
-lenses, would not be more disturbing than a strong emotion in a
-nature such as his. And yet there was but one woman to him, and
-that woman was the late Irene Adler, of dubious and questionable
-memory.
-
-I had seen little of Holmes lately. My marriage had drifted us
-away from each other. My own complete happiness, and the
-home-centred interests which rise up around the man who first
-finds himself master of his own establishment, were sufficient to
-absorb all my attention, while Holmes, who loathed every form of
-society with his whole Bohemian soul, remained in our lodgings in
-Baker Street, buried among his old books, and alternating from
-week to week between cocaine and ambition, the drowsiness of the
-drug, and the fierce energy of his own keen nature. He was still,
-as ever, deeply attracted by the study of crime, and occupied his
-immense faculties and extraordinary powers of observation in
-following out those clues, and clearing up those mysteries which
-had been abandoned as hopeless by the official police. From time
-to time I heard some vague account of his doings: of his summons
-to Odessa in the case of the Trepoff murder, of his clearing up
-of the singular tragedy of the Atkinson brothers at Trincomalee,
-and finally of the mission which he had accomplished so
-delicately and successfully for the reigning family of Holland.
-Beyond these signs of his activity, however, which I merely
-shared with all the readers of the daily press, I knew little of
-my former friend and companion.

+Yet another .INI file parser / writer. Created because the existing ones
+were either not general enough (allowing easy access to all parts of the
+original file) or made annoying assumptions about the format. And
+probably equal parts NIH. You might want to just write your own instead
+of using this one, you know that's where you'll end up in the end
+anyhow.

+
+Martini is a powerful package for quickly writing modular web applications/services in Golang.
+
+Language Translations: [Simplified Chinese (zh_CN)](translations/README_zh_cn.md)
+
+
+## Getting Started
+
+After installing Go and setting up your [GOPATH](http://golang.org/doc/code.html#GOPATH), create your first `.go` file. We'll call it `server.go`.
+
+~~~ go
+package main
+
+import "github.com/codegangsta/martini"
+
+func main() {
+  m := martini.Classic()
+  m.Get("/", func() string {
+    return "Hello world!"
+  })
+  m.Run()
+}
+~~~
+
+Then install the Martini package (**go 1.1** and greater is required):
+~~~
+go get github.com/codegangsta/martini
+~~~
+
+Then run your server:
+~~~
+go run server.go
+~~~
+
+You will now have a Martini webserver running on `localhost:3000`.
+
+## Getting Help
+
+Join the [Mailing list](https://groups.google.com/forum/#!forum/martini-go)
+
+Watch the [Demo Video](http://martini.codegangsta.io/#demo)
+
+## Features
+* Extremely simple to use.
+* Non-intrusive design.
+* Plays nice with other Golang packages.
+* Awesome path matching and routing.
+* Modular design - Easy to add functionality, easy to rip stuff out.
+* Lots of good handlers/middlewares to use.
+* Great 'out of the box' feature set.
+* **Fully compatible with the [http.HandlerFunc](http://godoc.org/net/http#HandlerFunc) interface.**
+
+## More Middleware
+For more middleware and functionality, check out the repositories in the  [martini-contrib](https://github.com/martini-contrib) organization.

+## Classic Martini
+To get up and running quickly, [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic) provides some reasonable defaults that work well for most web applications:
+~~~ go
+  m := martini.Classic()
+  // ... middleware and routing goes here
+  m.Run()
+~~~
+
+Below is some of the functionality [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic) pulls in automatically:
+  * Request/Response Logging - [martini.Logger](http://godoc.org/github.com/codegangsta/martini#Logger)
+  * Panic Recovery - [martini.Recovery](http://godoc.org/github.com/codegangsta/martini#Recovery)
+  * Static File serving - [martini.Static](http://godoc.org/github.com/codegangsta/martini#Static)
+  * Routing - [martini.Router](http://godoc.org/github.com/codegangsta/martini#Router)
+
+### Handlers
+Handlers are the heart and soul of Martini. A handler is basically any kind of callable function:
+~~~ go
+m.Get("/", func() {
+  println("hello world")
+})
+~~~
+
+#### Return Values
+If a handler returns something, Martini will write the result to the current [http.ResponseWriter](http://godoc.org/net/http#ResponseWriter) as a string:
+~~~ go
+m.Get("/", func() string {
+  return "hello world" // HTTP 200 : "hello world"
+})
+~~~
+
+You can also optionally return a status code:
+~~~ go
+m.Get("/", func() (int, string) {
+  return 418, "i'm a teapot" // HTTP 418 : "i'm a teapot"
+})
+~~~
+
+#### Service Injection
+Handlers are invoked via reflection. Martini makes use of *Dependency Injection* to resolve dependencies in a Handlers argument list. **This makes Martini completely  compatible with golang's `http.HandlerFunc` interface.** 
+
+If you add an argument to your Handler, Martini will search its list of services and attempt to resolve the dependency via type assertion:
+~~~ go
+m.Get("/", func(res http.ResponseWriter, req *http.Request) { // res and req are injected by Martini
+  res.WriteHeader(200) // HTTP 200
+})
+~~~
+
+The following services are included with [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic):
+  * [*log.Logger](http://godoc.org/log#Logger) - Global logger for Martini.
+  * [martini.Context](http://godoc.org/github.com/codegangsta/martini#Context) - http request context.
+  * [martini.Params](http://godoc.org/github.com/codegangsta/martini#Params) - `map[string]string` of named params found by route matching.
+  * [martini.Routes](http://godoc.org/github.com/codegangsta/martini#Routes) - Route helper service.
+  * [http.ResponseWriter](http://godoc.org/net/http/#ResponseWriter) - http Response writer interface.
+  * [*http.Request](http://godoc.org/net/http/#Request) - http Request.
+
+### Routing
+In Martini, a route is an HTTP method paired with a URL-matching pattern.
+Each route can take one or more handler methods:
+~~~ go
+m.Get("/", func() {
+  // show something
+})
+
+m.Patch("/", func() {
+  // update something
+})
+
+m.Post("/", func() {
+  // create something
+})
+
+m.Put("/", func() {
+  // replace something
+})
+
+m.Delete("/", func() {
+  // destroy something
+})
+
+m.Options("/", func() {
+  // http options
+})
+
+m.NotFound(func() {
+  // handle 404
+})
+~~~
+
+Routes are matched in the order they are defined. The first route that
+matches the request is invoked.
+
+Route patterns may include named parameters, accessible via the [martini.Params](http://godoc.org/github.com/codegangsta/martini#Params) service:
+~~~ go
+m.Get("/hello/:name", func(params martini.Params) string {
+  return "Hello " + params["name"]
+})
+~~~
+
+Routes can be matched with regular expressions and globs as well:
+~~~ go
+m.Get("/hello/**", func(params martini.Params) string {
+  return "Hello " + params["_1"]
+})
+~~~
+
+Route handlers can be stacked on top of each other, which is useful for things like authentication and authorization:
+~~~ go
+m.Get("/secret", authorize, func() {
+  // this will execute as long as authorize doesn't write a response
+})
+~~~
+
+Route groups can be added too using the Group method.
+~~~ go
+m.Group("/books", func(r Router) {
+    r.Get("/:id", GetBooks)
+    r.Post("/new", NewBook)
+    r.Put("/update/:id", UpdateBook)
+    r.Delete("/delete/:id", DeleteBook)
+})
+~~~
+
+Just like you can pass middlewares to a handler you can pass middlewares to groups.
+~~~ go
+m.Group("/books", func(r Router) {
+    r.Get("/:id", GetBooks)
+    r.Post("/new", NewBook)
+    r.Put("/update/:id", UpdateBook)
+    r.Delete("/delete/:id", DeleteBook)
+}, MyMiddleware1, MyMiddleware2)
+~~~
+
+### Services
+Services are objects that are available to be injected into a Handler's argument list. You can map a service on a *Global* or *Request* level.
+
+#### Global Mapping
+A Martini instance implements the inject.Injector interface, so mapping a service is easy:
+~~~ go
+db := &MyDatabase{}
+m := martini.Classic()
+m.Map(db) // the service will be available to all handlers as *MyDatabase
+// ...
+m.Run()
+~~~
+
+#### Request-Level Mapping
+Mapping on the request level can be done in a handler via [martini.Context](http://godoc.org/github.com/codegangsta/martini#Context):
+~~~ go
+func MyCustomLoggerHandler(c martini.Context, req *http.Request) {
+  logger := &MyCustomLogger{req}
+  c.Map(logger) // mapped as *MyCustomLogger
+}
+~~~
+
+#### Mapping values to Interfaces
+One of the most powerful parts about services is the ability to map a service to an interface. For instance, if you wanted to override the [http.ResponseWriter](http://godoc.org/net/http#ResponseWriter) with an object that wrapped it and performed extra operations, you can write the following handler:
+~~~ go
+func WrapResponseWriter(res http.ResponseWriter, c martini.Context) {
+  rw := NewSpecialResponseWriter(res)
+  c.MapTo(rw, (*http.ResponseWriter)(nil)) // override ResponseWriter with our wrapper ResponseWriter
+}
+~~~
+
+### Serving Static Files
+A [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic) instance automatically serves static files from the "public" directory in the root of your server.
+You can serve from more directories by adding more [martini.Static](http://godoc.org/github.com/codegangsta/martini#Static) handlers.
+~~~ go
+m.Use(martini.Static("assets")) // serve from the "assets" directory as well
+~~~
+
+## Middleware Handlers
+Middleware Handlers sit between the incoming http request and the router. In essence they are no different than any other Handler in Martini. You can add a middleware handler to the stack like so:
+~~~ go
+m.Use(func() {
+  // do some middleware stuff
+})
+~~~
+
+You can have full control over the middleware stack with the `Handlers` function. This will replace any handlers that have been previously set:
+~~~ go
+m.Handlers(
+  Middleware1,
+  Middleware2,
+  Middleware3,
+)
+~~~
+
+Middleware Handlers work really well for things like logging, authorization, authentication, sessions, gzipping, error pages and any other operations that must happen before or after an http request:
+~~~ go
+// validate an api key
+m.Use(func(res http.ResponseWriter, req *http.Request) {
+  if req.Header.Get("X-API-KEY") != "secret123" {
+    res.WriteHeader(http.StatusUnauthorized)
+  }
+})
+~~~
+

+[Context.Next()](http://godoc.org/github.com/codegangsta/martini#Context) is an optional function that Middleware Handlers can call to yield the until after the other Handlers have been executed. This works really well for any operations that must happen after an http request:
+~~~ go
+// log before and after a request
+m.Use(func(c martini.Context, log *log.Logger){
+  log.Println("before a request")
+
+  c.Next()
+  
+  log.Println("after a request")
+})
+~~~
+
+## Martini Env
+
+Some Martini handlers make use of the `martini.Env` global variable to provide special functionality for development environments vs production environments. It is reccomended that the `MARTINI_ENV=production` environment variable to be set when deploying a Martini server into a production environment.
+
+## FAQ
+
+### Where do I find middleware X?
+
+Start by looking in the [martini-contrib](https://github.com/martini-contrib) projects. If it is not there feel free to contact a martini-contrib team member about adding a new repo to the organization.
+
+* [auth](https://github.com/martini-contrib/auth) - Handlers for authentication.
+* [binding](https://github.com/martini-contrib/binding) - Handler for mapping/validating a raw request into a structure.
+* [gzip](https://github.com/martini-contrib/gzip) - Handler for adding gzip compress to requests
+* [render](https://github.com/martini-contrib/render) - Handler that provides a service for easily rendering JSON and HTML templates.
+* [acceptlang](https://github.com/martini-contrib/acceptlang) - Handler for parsing the `Accept-Language` HTTP header.
+* [sessions](https://github.com/martini-contrib/sessions) - Handler that provides a Session service.
+* [strip](https://github.com/martini-contrib/strip) - URL Prefix stripping.
+* [method](https://github.com/martini-contrib/method) - HTTP method overriding via Header or form fields.
+* [secure](https://github.com/martini-contrib/secure) - Implements a few quick security wins.
+* [encoder](https://github.com/martini-contrib/encoder) - Encoder service for rendering data in several formats and content negotiation.
+* [cors](https://github.com/martini-contrib/cors) - Handler that enables CORS support.
+* [oauth2](https://github.com/martini-contrib/oauth2) - Handler that provides OAuth 2.0 login for Martini apps. Google Sign-in, Facebook Connect and Github login is supported.
+
+### How do I integrate with existing servers?
+
+A Martini instance implements `http.Handler`, so it can easily be used to serve subtrees 
+on existing Go servers. For example this is a working Martini app for Google App Engine:
+
+~~~ go
+package hello
+
+import (
+  "net/http"
+  "github.com/codegangsta/martini"
+)
+
+func init() {
+  m := martini.Classic()
+  m.Get("/", func() string {
+    return "Hello world!"
+  })
+  http.Handle("/", m)
+}
+~~~
+
+### How do I change the port/host?
+
+Martini's `Run` function looks for the PORT and HOST environment variables and uses those. Otherwise Martini will default to localhost:3000.
+To have more flexibility over port and host, use the `http.ListenAndServe` function instead.
+
+~~~ go
+  m := martini.Classic()
+  // ...
+  log.Fatal(http.ListenAndServe(":8080", m))
+~~~
+
+### Live code reload?
+
+[gin](https://github.com/codegangsta/gin) and [fresh](https://github.com/pilu/fresh) both live reload martini apps.

+# Martini  [![wercker status](https://app.wercker.com/status/174bef7e3c999e103cacfe2770102266 "wercker status")](https://app.wercker.com/project/bykey/174bef7e3c999e103cacfe2770102266) [![GoDoc](https://godoc.org/github.com/codegangsta/martini?status.png)](http://godoc.org/github.com/codegangsta/martini)
+
+Martini是一个强大为了编写模块化Web应用而生的GO语言框架.
+
+## 第一个应用
+
+在你安装了GO语言和设置了你的[GOPATH](http://golang.org/doc/code.html#GOPATH)之后, 创建你的自己的`.go`文件, 这里我们假设它的名字叫做 `server.go`.
+
+~~~ go
+package main
+
+import "github.com/codegangsta/martini"
+
+func main() {
+  m := martini.Classic()
+  m.Get("/", func() string {
+    return "Hello world!"
+  })
+  m.Run()
+}
+~~~
+
+然后安装Martini的包. (注意Martini需要Go语言1.1或者以上的版本支持):
+~~~
+go get github.com/codegangsta/martini
+~~~
+
+最后运行你的服务:
+~~~
+go run server.go
+~~~
+
+这时你将会有一个Martini的服务监听了, 地址是: `localhost:3000`.
+
+## 获得帮助
+
+请加入: [邮件列表](https://groups.google.com/forum/#!forum/martini-go)
+
+或者可以查看在线演示地址: [演示视频](http://martini.codegangsta.io/#demo)
+
+## 功能列表
+* 使用极其简单.
+* 无侵入式的设计.
+* 很好的与其他的Go语言包协同使用.
+* 超赞的路径匹配和路由.
+* 模块化的设计 - 容易插入功能件，也容易将其拔出来.
+* 已有很多的中间件可以直接使用.
+* 框架内已拥有很好的开箱即用的功能支持.
+* **完全兼容[http.HandlerFunc](http://godoc.org/net/http#HandlerFunc)接口.**
+
+## 更多中间件
+更多的中间件和功能组件, 请查看代码仓库: [martini-contrib](https://github.com/martini-contrib).
+
+## 目录
+* [核心 Martini](#classic-martini)
+  * [处理器](#handlers)
+  * [路由](#routing)
+  * [服务](#services)
+  * [服务静态文件](#serving-static-files)
+* [中间件处理器](#middleware-handlers)
+  * [Next()](#next)
+* [常见问答](#faq)
+
+## 核心 Martini
+为了更快速的启用Martini, [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic) 提供了一些默认的方便Web开发的工具:
+~~~ go
+  m := martini.Classic()
+  // ... middleware and routing goes here
+  m.Run()
+~~~
+
+下面是Martini核心已经包含的功能 [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic):
+  * Request/Response Logging （请求/相应日志） - [martini.Logger](http://godoc.org/github.com/codegangsta/martini#Logger)
+  * Panic Recovery （容错） - [martini.Recovery](http://godoc.org/github.com/codegangsta/martini#Recovery)
+  * Static File serving （静态文件服务） - [martini.Static](http://godoc.org/github.com/codegangsta/martini#Static)
+  * Routing （路由） - [martini.Router](http://godoc.org/github.com/codegangsta/martini#Router)
+
+### 处理器
+处理器是Martini的灵魂和核心所在. 一个处理器基本上可以是任何的函数:
+~~~ go
+m.Get("/", func() {
+  println("hello world")
+})
+~~~
+
+#### 返回值
+当一个处理器返回结果的时候, Martini将会把返回值作为字符串写入到当前的[http.ResponseWriter](http://godoc.org/net/http#ResponseWriter)里面:
+~~~ go
+m.Get("/", func() string {
+  return "hello world" // HTTP 200 : "hello world"
+})
+~~~
+
+另外你也可以选择性的返回多一个状态码:
+~~~ go
+m.Get("/", func() (int, string) {
+  return 418, "i'm a teapot" // HTTP 418 : "i'm a teapot"
+})
+~~~
+
+#### 服务的注入 
+处理器是通过反射来调用的. Martini 通过*Dependency Injection* *（依赖注入）* 来为处理器注入参数列表. **这样使得Martini与Go语言的`http.HandlerFunc`接口完全兼容.** 
+
+如果你加入一个参数到你的处理器, Martini将会搜索它参数列表中的服务，并且通过类型判断来解决依赖关系:
+~~~ go
+m.Get("/", func(res http.ResponseWriter, req *http.Request) { // res 和 req 是通过Martini注入的
+  res.WriteHeader(200) // HTTP 200
+})
+~~~
+
+下面的这些服务已经被包含在核心Martini中: [martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic):
+  * [*log.Logger](http://godoc.org/log#Logger) - Martini的全局日志.
+  * [martini.Context](http://godoc.org/github.com/codegangsta/martini#Context) - http request context （请求上下文）.
+  * [martini.Params](http://godoc.org/github.com/codegangsta/martini#Params) - `map[string]string` of named params found by route matching. （名字和参数键值对的参数列表）
+  * [martini.Routes](http://godoc.org/github.com/codegangsta/martini#Routes) - Route helper service. （路由协助处理）
+  * [http.ResponseWriter](http://godoc.org/net/http/#ResponseWriter) - http Response writer interface. (响应结果的流接口)
+  * [*http.Request](http://godoc.org/net/http/#Request) - http Request. （http请求)
+
+### 路由
+在Martini中, 路由是一个HTTP方法配对一个URL匹配模型. 每一个路由可以对应一个或多个处理器方法:
+~~~ go
+m.Get("/", func() {
+  // 显示
+})
+
+m.Patch("/", func() {
+  // 更新
+})
+
+m.Post("/", func() {
+  // 创建
+})
+
+m.Put("/", func() {
+  // 替换
+})
+
+m.Delete("/", func() {
+  // 删除
+})
+
+m.Options("/", func() {
+  // http 选项
+})
+
+m.NotFound(func() {
+  // 处理 404
+})
+~~~
+
+路由匹配的顺序是按照他们被定义的顺序执行的. 最先被定义的路由将会首先被用户请求匹配并调用.
+
+路由模型可能包含参数列表, 可以通过[martini.Params](http://godoc.org/github.com/codegangsta/martini#Params)服务来获取:
+~~~ go
+m.Get("/hello/:name", func(params martini.Params) string {
+  return "Hello " + params["name"]
+})
+~~~
+
+路由匹配可以通过正则表达式或者glob的形式:
+~~~ go
+m.Get("/hello/**", func(params martini.Params) string {
+  return "Hello " + params["_1"]
+})
+~~~
+
+路由处理器可以被相互叠加使用, 例如很有用的地方可以是在验证和授权的时候:
+~~~ go
+m.Get("/secret", authorize, func() {
+  // 该方法将会在authorize方法没有输出结果的时候执行.
+})
+~~~
+
+### 服务
+服务即是被注入到处理器中的参数. 你可以映射一个服务到 *全局* 或者 *请求* 的级别.
+
+
+#### 全局映射
+如果一个Martini实现了inject.Injector的接口, 那么映射成为一个服务就非常简单:
+~~~ go
+db := &MyDatabase{}
+m := martini.Classic()
+m.Map(db) // *MyDatabase 这个服务将可以在所有的处理器中被使用到.
+// ...
+m.Run()
+~~~
+
+#### 请求级别的映射
+映射在请求级别的服务可以用[martini.Context](http://godoc.org/github.com/codegangsta/martini#Context)来完成:
+~~~ go
+func MyCustomLoggerHandler(c martini.Context, req *http.Request) {
+  logger := &MyCustomLogger{req}
+  c.Map(logger) // 映射成为了 *MyCustomLogger
+}
+~~~
+
+#### 映射值到接口
+关于服务最强悍的地方之一就是它能够映射服务到接口. 例如说, 假设你想要覆盖[http.ResponseWriter](http://godoc.org/net/http#ResponseWriter)成为一个对象, 那么你可以封装它并包含你自己的额外操作, 你可以如下这样来编写你的处理器:
+~~~ go
+func WrapResponseWriter(res http.ResponseWriter, c martini.Context) {
+  rw := NewSpecialResponseWriter(res)
+  c.MapTo(rw, (*http.ResponseWriter)(nil)) // 覆盖 ResponseWriter 成为我们封装过的 ResponseWriter
+}
+~~~
+
+### 服务静态文件
+[martini.Classic()](http://godoc.org/github.com/codegangsta/martini#Classic) 默认会服务位于你服务器环境根目录下的"public"文件夹.
+你可以通过加入[martini.Static](http://godoc.org/github.com/codegangsta/martini#Static)的处理器来加入更多的静态文件服务的文件夹.
+~~~ go
+m.Use(martini.Static("assets")) // 也会服务静态文件于"assets"的文件夹
+~~~
+
+## 中间件处理器
+中间件处理器是工作于请求和路由之间的. 本质上来说和Martini其他的处理器没有分别. 你可以像如下这样添加一个中间件处理器到它的堆中:
+~~~ go
+m.Use(func() {
+  // 做一些中间件该做的事情
+})
+~~~
+
+你可以通过`Handlers`函数对中间件堆有完全的控制. 它将会替换掉之前的任何设置过的处理器:
+~~~ go
+m.Handlers(
+  Middleware1,
+  Middleware2,
+  Middleware3,
+)
+~~~
+
+中间件处理器可以非常好处理一些功能，像logging(日志), authorization(授权), authentication(认证), sessions(会话), error pages(错误页面), 以及任何其他的操作需要在http请求发生之前或者之后的:
+
+~~~ go
+// 验证api密匙
+m.Use(func(res http.ResponseWriter, req *http.Request) {
+  if req.Header.Get("X-API-KEY") != "secret123" {
+    res.WriteHeader(http.StatusUnauthorized)
+  }
+})
+~~~
+
+### Next()
+[Context.Next()](http://godoc.org/github.com/codegangsta/martini#Context)是一个可选的函数用于中间件处理器暂时放弃执行直到其他的处理器都执行完毕. 这样就可以很好的处理在http请求完成后需要做的操作.
+~~~ go
+// log 记录请求完成前后  (*译者注: 很巧妙，掌声鼓励.)
+m.Use(func(c martini.Context, log *log.Logger){
+  log.Println("before a request")
+
+  c.Next()
+  
+  log.Println("after a request")
+})
+~~~
+

+
+### 我如何整合到我现有的服务器中?
+
+由于Martini实现了 `http.Handler`, 所以它可以很简单的应用到现有Go服务器的子集中. 例如说这是一段在Google App Engine中的示例:
+
+~~~ go
+package hello
+
+import (
+  "net/http"
+  "github.com/codegangsta/martini"
+)
+
+func init() {
+  m := martini.Classic()
+  m.Get("/", func() string {
+    return "Hello world!"
+  })
+  http.Handle("/", m)
+}
+~~~
+
+### 我如何修改port/host?
+
+Martini的`Run`函数会检查PORT和HOST的环境变量并使用它们. 否则Martini将会默认使用localhost:3000
+如果想要自定义PORT和HOST, 使用`http.ListenAndServe`函数来代替.
+
+~~~ go
+  m := martini.Classic()
+  // ...
+  http.ListenAndServe(":8080", m)
+~~~
