-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of experience,
-education, socio-economic status, nationality, personal appearance, race,
-religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-  advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at security@syncthing.net. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of an incident.
-Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.
-
-## Attribution
-
-This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
-available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-## 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. :)
-
-## Contributing Translations
-
-All translations are done via
-[Weblate](https://hosted.weblate.org/projects/syncthing/). If you wish
-to contribute to a translation, just head over there and sign up.
-Before every release, the language resources are updated from the
-latest info on Weblate.
-
-Note that the previously used service at
-[Transifex](https://www.transifex.com/projects/p/syncthing/) is being
-retired and we kindly ask you to sign up on Weblate for continued
-involvement.
-
-## Contributing Documentation
-
-Updates to the [documentation site](https://docs.syncthing.net/) can be
-made as pull requests on the [documentation
-repository](https://github.com/syncthing/docs).
-
-## Contributing Code
-
-Every contribution is welcome. If you want to contribute but are unsure
-where to start, any open issues are fair game! Here's a short rundown of
-what you need to keep in mind:
-
-- Don't worry. You are not expected to get everything right on the first
-  attempt, we'll guide you through it.
-
-- Make sure there is an
-  [issue](https://github.com/syncthing/syncthing/issues) that describes the
-  change you want to do. If the thing you want to do does not have an issue
-  yet, please file one before starting work on it.
-
-- Fork the repository and make your changes in a new branch. Once it's ready
-  for review, create a pull request.
-
-### Authorship
-
-All code authors are listed in the AUTHORS file. When your first pull
-request is accepted your details are added to the AUTHORS file and the list
-of authors in the GUI. Commits must be made with the same name and email as
-listed in the AUTHORS file. To accomplish this, ensure that your git
-configuration is set correctly prior to making your first commit:
-
-    $ git config --global user.name "Jane Doe"
-    $ git config --global user.email janedoe@example.com
-
-You must be reachable on the given email address. If you do not wish to use
-your real name for whatever reason, using a nickname or pseudonym is
-perfectly acceptable.
-
-### The Developer Certificate of Origin (DCO)
-
-The Syncthing project requires the Developer Certificate of Origin (DCO)
-sign-off on pull requests (PRs). This means that all commit messages must
-contain a signature line to indicate that the developer accepts the DCO.
-
-The DCO is a lightweight way for contributors to certify that they wrote (or
-otherwise have the right to submit) the code and changes they are
-contributing to the project. Here is the full [text of the
-DCO](https://developercertificate.org):
-
----
-
-By making a contribution to this project, I certify that:
-
-1. The contribution was created in whole or in part by me and I have the
-   right to submit it under the open source license indicated in the file;
-   or
-
-2. The contribution is based upon previous work that, to the best of my
-   knowledge, is covered under an appropriate open source license and I have
-   the right under that license to submit that work with modifications,
-   whether created in whole or in part by me, under the same open source
-   license (unless I am permitted to submit under a different license), as
-   indicated in the file; or
-
-3. The contribution was provided directly to me by some other person who
-   certified (1), (2) or (3) and I have not modified it.
-
-4. I understand and agree that this project and the contribution are public
-   and that a record of the contribution (including all personal information
-   I submit with it, including my sign-off) is maintained indefinitely and
-   may be redistributed consistent with this project or the open source
-   license(s) involved.
-
----
-
-Contributors indicate that they adhere to these requirements by adding
-a `Signed-off-by` line to their commit messages.  For example:
-
-    This is my commit message
-
-    Signed-off-by: Random J Developer <random@developer.example.org>
-
-The name and email address in this line must match those of the committing
-author, and be the same as what you want in the AUTHORS file as per above.
-
-### Coding Style
-
-#### General
-
-- All text files use Unix line endings. The git settings already present in
-  the repository attempt to enforce this.
-
-- When making changes, follow the brace and parenthesis style of the
-  surrounding code.
-
-#### Go Specific
-
-- Follow the conventions laid out in [Effective
-  Go](https://go.dev/doc/effective_go) as much as makes sense. The review
-  guidelines in [Go Code Review
-  Comments](https://github.com/golang/go/wiki/CodeReviewComments) should
-  generally be followed.
-
-- Each commit should be `go fmt` clean.
-
-- Imports are grouped per `goimports` standard; that is, standard
-  library first, then third party libraries after a blank line.
-
-### Commits
-
-- Commit messages (and pull request titles) should follow the [conventional
-  commits](https://www.conventionalcommits.org/en/v1.0.0/) specification and
-  be in lower case.
-
-- We use a scope description in the commit message subject. This is the
-  component of Syncthing that the commit affects. For example, `gui`,
-  `protocol`, `scanner`, `upnp`, etc -- typically, the part after
-  `internal/`, `lib/` or `cmd/` in the package path. If the commit doesn't
-  affect a specific component, such as for changes to the build system or
-  documentation, the scope should be omitted. The same goes for changes that
-  affect many components which would be cumbersome to list.
-
-- Commits that resolve an existing issue must include the issue number
-  as `(fixes #123)` at the end of the commit message subject. A correctly
-  formatted commit message subject looks like this:
-
-      feat(dialer): add env var to disable proxy fallback (fixes #3006)
-
-- If the commit message subject doesn't say it all, one or more paragraphs of
-  describing text should be added to the commit message. This should explain
-  why the change is made and what it accomplishes.
-
-- When drafting a pull request, please feel free to add commits with
-  corrections and merge from `main` when necessary. This provides a clear time
-  line with changes and simplifies review. Do not, in general, rebase your
-  commits, as this makes review harder.
-
-- Pull requests are merged to `main` using squash merge. The "stream of
-  consciousness" set of commits described in the previous point will be reduced
-  to a single commit at merge time. The pull request title and description will
-  be used as the commit message.
-
-### Tests
-
-Yes please, do add tests when adding features or fixing bugs. Also, when a
-pull request is filed a number of automatic tests are run on the code. This
-includes:
-
-- That the code actually builds and the test suite passes.
-
-- That the code is correctly formatted (`go fmt`).
-
-- That the commits are based on a reasonably recent `main`.
-
-- That the output from `go lint` and `go vet` is clean. (This checks for a
-  number of potential problems the compiler doesn't catch.)
+Please do contribute! If you want to contribute but are unsure where to
+start, the [Contributions Needed
+page](https://github.com/calmh/syncthing/wiki/Contributions-Needed)
+lists areas in need of attention.
 
 ## Licensing
 
-All contributions are made available under the same license as the already
-existing material being contributed to. For most of the project and unless
-otherwise stated this means MPLv2, but there are exceptions:
+All contributions are made under the same MIT License as the rest of the
+project, except documentation which is licensed under the Creative
+Commons Attribution 4.0 International License. You retain the copyright
+to code you have written.
 
-- Certain commands (under cmd/...) may have a separate license, indicated by
-  the presence of a LICENSE file in the corresponding directory.
+When accepting your first contribution, the maintainer of the project
+will ensure that you are added to the CONTRIBUTORS file.
 
-- The documentation (man/...) is licensed under the Creative Commons

+## Building
 
-Regardless of the license in effect, you retain the copyright to your
-contribution.
+[See the wiki](https://github.com/calmh/syncthing/wiki/Building)
+
+## Branches
+
+ - `master` is the main branch containing good code that will end up in
+   the next release. You should base your work on it. It won't ever be
+   rebased or force-pushed to.
+
+ - `vx.y` branches exist to make patch releases on otherwise obsolete
+   minor releases. Should only contain fixes cherry picked from master.
+   Don't base any work on them.
+
+ - Other branches are probably topic branches and may be subject to
+   rebasing. Don't base any work on them unless you specifically know
+   otherwise.
+
+## Tags
+
+All releases are tagged semver style as `vx.y.z`. Release tags are
+signed by GPG key BCE524C7.
+
+## Tests
+
+Yes please!
+
+## Style
+
+`go fmt`

-Protecting the user's data is paramount. We take every reasonable precaution
-to avoid corrupting the user's files.
-
-> This is the overriding goal, without which synchronizing files becomes
-> pointless. This means that we do not make unsafe trade offs for the sake
-> of performance or, in some cases, even usability.
-
-### 2. Secure Against Attackers
-
-Again, protecting the user's data is paramount. Regardless of our other
-goals, we must never allow the user's data to be susceptible to eavesdropping
-or modification by unauthorized parties.
-
-> This should be understood in context. It is not necessarily reasonable to
-> expect Syncthing to be resistant against well equipped state level
-> attackers. We will, however, do our best. Note also that this is different
-> from anonymity which is not, currently, a goal.
-
-### 3. Easy to Use
-
-Syncthing should be approachable, understandable, and inclusive.
-
-> Complex concepts and maths form the base of Syncthing's functionality.
-> This should nonetheless be abstracted or hidden to a degree where
-> Syncthing is usable by the general public.
-
-### 4. Automatic
-
-User interaction should be required only when absolutely necessary.
-
-> Specifically this means that changes to files are picked up without
-> prompting, conflicts are resolved without prompting and connections are
-> maintained without prompting. We only prompt the user when it is required
-> to fulfill one of the (overriding) Secure, Safe or Easy goals.
-
-### 5. Universally Available
-
-Syncthing should run on every common computer. We are mindful that the
-latest technology is not always available to every individual.
-
-> Computers include desktops, laptops, servers, virtual machines, small
-> general purpose computers such as Raspberry Pis and, *where possible*,
-> tablets and phones. NAS appliances, toasters, cars, firearms, thermostats,
-> and so on may include computing capabilities but it is not our goal for
-> Syncthing to run smoothly on these devices.
-
-### 6. For Individuals
-
-Syncthing is primarily about empowering the individual user with safe,
-secure, and easy to use file synchronization.
-
-> We acknowledge that it's also useful in an enterprise setting and include
-> functionality to support that. If this is in conflict with the
-> requirements of the individual, those will however take priority.
-
-### 7. Everything Else
-
-There are many things we care about that don't make it on to the list. It is
-fine to optimize for these values as well, as long as they are not in
-conflict with the stated goals above.
-
-> For example, performance is a thing we care about. We just don't care more
-> about it than safety, security, etc. Maintainability of the code base and
-> providing entertainment value for the maintainers are also things that
-> matter. It is understood that there are aspects of Syncthing that are
-> suboptimal or even in opposition with the goals above. However, we
-> continuously strive to align Syncthing more and more with these goals.

+ini [![Build Status](https://drone.io/github.com/calmh/ini/status.png)](https://drone.io/github.com/calmh/ini/latest)
+===
+
+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.
+

+Example
+-------
+
+```go
+fd, _ := os.Open("foo.ini")
+cfg := ini.Parse(fd)
+fd.Close()
+
+val := cfg.Get("general", "foo")
+cfg.Set("general", "bar", "baz")
+
+fd, _ = os.Create("bar.ini")
+err := cfg.Write(fd)

+
+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

+## 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)
+  }
+})
+~~~
+
+### Next()
+[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.

+* [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).

+
+## 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)
+~~~
+

+

+continue to comply in full to this Library. If you modify this Library, you
+may apply this exception to your version of this Library, but you are not
+obliged to do so. If you do not wish to do so, delete this exception

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
