+# 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, sex characteristics, 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 i@xiaozhou.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

-## Pre-condition
+## Pre-conditions
 
-* Register and own a domain.
+To use GoDNS, it is assumed:
+* You registered (now own) a domain
+* Domain was delegated to a supported [DNS provider](#supported-dns-providers) (i.e. it has nameserver `NS` records pointing at a supported provider)
 
-* Domain's nameserver points to [DNSPod](https://www.dnspod.cn/) or [HE.net](https://dns.he.net/) or [Cloudflare](https://www.cloudflare.com/).
+Alternatively, you can sign in to [DuckDNS](https://www.duckdns.org) (with a social account) and get a subdomain on the duckdns.org domain for free.
 
-## Get it
+## Installation
 
-### Build it from source code
+Build GoDNS by running (from the root of the repository):
-
-* Get source code from Github:
 
 ```bash
-git clone https://github.com/timothyye/godns.git
+cd cmd/godns  # go to the GoDNS directory
-```
+go get -v     # get dependencies
-* Go into the godns directory, get related library and then build it:
+go build      # build
-
-```bash
-cd cmd/godns
-go get -v
-go build
 ```
 
-### Download from releases
+You can also download a compiled binary from the [releases](https://github.com/TimothyYe/godns/releases).
+## Usage
 
-Download compiled binaries from [releases](https://github.com/TimothyYe/godns/releases)
+Print usage/help by running:
-
-## Get help
 
 ```bash
 $ ./godns -h
 Usage of ./godns:
   -c string
         Specify a config file (default "./config.json")
-  -d    Run it as docker mode
   -h    Show help
 ```
 
-## Config it
+## Configuration
 
-* Get [config_sample.json](https://github.com/timothyye/godns/blob/master/config_sample.json) from Github.
+### Overview
-* Rename it to **config.json**.
-* Configure your provider, domain/sub-domain info, username and password, etc.
-* Configure the SMTP options if you want, a mail notification will sent to your mailbox once the IP is changed.
-* Save it in the same directory of GoDNS, or use -c=your_conf_path command.
 
-### Config example for Cloudflare
+* Make a copy of [config_sample.json](./config_sample.json) and name it `config.json`
+* Configure your provider, domain/subdomain info, credentials, etc.
+* Configure a notification medium (e.g. SMTP to receive emails) to get notified when your IP address changes
+* Place the file in the same directory of GoDNS or use the `-c=path/to/your/file.json` option
 
-For Cloudflare, you need to provide email & Global API Key as password, and config all the domains & subdomains.
+### Configuration properties
+
+* `provider` — One of the [supported provider to use](#supported-dns-providers): `Cloudflare`, `Google`, `DNSPod`, `AliDNS`, `HE`, `DuckDNS` or `Dreamhost`.
+* `email` — Email or account name of the DNS provider.
+* `password` — Password of the DNS provider.
+* `login_token` — API token of the DNS provider.
+* `domains` — Domains list, with your sub domains.
+* `ip_url` — A URL for fetching one's public IPv4 address.
+* `ipv6_url` — A URL for fetching one's public IPv6 address.
+* `ip_type` — Switch deciding if IPv4 or IPv6 should be used (when [supported](#supported-dns-providers)). Available values: `IPv4` or `IPv6`.
+* `interval` — How often (in seconds) the public IP should be updated.
+* `socks5_proxy` — Socks5 proxy server.
+* `resolver` — Address of a public DNS server to use. For instance to use [Google's public DNS](https://developers.google.com/speed/public-dns/docs/using), you can set `8.8.8.8` when using GoDNS in IPv4 mode or `2001:4860:4860::8888` in IPv6 mode.
+
+### Configuration examples
+
+#### Cloudflare

-For some reasons if you want to get an IP directly from the interface, say `eth0` for Linux or `Local Area Connection` for Windows, update config file like this:
+GoDNS can send a notification each time the IP changes.
-```json
-  "ip_url": "",
-  "ip_interface": "eth0",
-```
 
-If you set both `ip_url` and `ip_interface`, it first tries to get an IP address online, and if not succeed, gets

+#### Telegram
 
-You can also use SOCKS5 proxy, just fill SOCKS5 address to the ```socks5_proxy``` item:
+To receive a [Telegram](https://telegram.org/) message each time the IP changes, update your configuration with the following snippet:
 
 ```json

+
+The `message_template` property supports [markdown](https://www.markdownguide.org). New lines needs to be escaped with `\n`.
+
+### Miscellaneous topics
+
+#### IPv6 support
+
+Most of the [providers](#supported-dns-providers) support IPv6.
+
+To enable the `IPv6` support of GoDNS, there are two solutions to choose from:
+
+1. Use an online service to lookup the external IPv6
+
+   For that:
+
+   - Set the `ip_type` as `IPv6`, and make sure the `ipv6_url` is configured
+   - Create an `AAAA` record instead of an `A` record in your DNS provider
+
+   <details>
+   <summary>Configuration example</summary>
+
+   ```json
+   {
+     "domains": [
+       {
+         "domain_name": "example.com",
+         "sub_domains": [
+           "ipv6"
+         ]
+       }
+     ],
+     "resolver": "2001:4860:4860::8888",
+     "ipv6_url": "https://api-ipv6.ip.sb/ip",
+     "ip_type": "IPv6"
+   }
+   ```
+   </details>
+
+
+2. Let GoDNS find the IPv6 of the network interface of the machine it is running on (more on that [later](#network-interface-ip-address)).
+
+   For this to happen, just leave `ip_url` and `ipv6_url` empty.
+
+   Note that the network interface must be configured with an IPv6 for this to work.
+
+#### Network interface IP address
+
+For some reasons if you want to get the IP address associated to a network interface (instead of performing an online lookup), you can specify it in the configuration file this way:
+
+```json
+...
+  "ip_url": "",
+  "ip_interface": "interface-name",
+...
+```
+
+With `interface-name` replaced by the name of the network interface, e.g. `eth0` on Linux or `Local Area Connection` on Windows.
+
+Note: If `ip_url` is also specified, it will be used to perform an online lookup first and the network interface IP will be used as a fallback in case of failure.
+
+#### SOCKS5 proxy support
+
+You can make all remote calls go through a [SOCKS5 proxy](https://en.wikipedia.org/wiki/SOCKS#SOCKS5) by specifying it in the configuration file this way:
+
+```json
+...
+"socks5_proxy": "127.0.0.1:7070"
+"use_proxy": true
+...
+```
+
+## Running GoDNS
+
+There are few ways to run GoDNS.
+
+### As a manual daemon
 
 ```bash
 nohup ./godns &
 ```
 
-## Run it as a daemon, manage it via Upstart
+Note: when the program stops, it will not be restarted.
 
-* Install `upstart` first
+### As a managed daemon (with upstart)
-* Copy `./upstart/godns.conf` to `/etc/init`
+
-* Start it as a system service:
+1. Install `upstart` first (if not available already)
+2. Copy `./upstart/godns.conf` to `/etc/init` (and tweak it to your needs)
+3. Start the service:
 
    ```bash
    sudo start godns
    ```
 
-## Run it as a daemon, manage it via Systemd
+### As a managed daemon (with systemd)
 
-* Modify `./systemd/godns.service` and config it.
+1. Install `systemd` first (it not available already)
-* Copy `./systemd/godns.service` to `/lib/systemd/system`
+2. Copy `./systemd/godns.service` to `/lib/systemd/system` (and tweak it to your needs)
-* Start it as a systemd service:
+3. Start the service:
 
    ```bash
    sudo systemctl enable godns
    sudo systemctl start godns
    ```
 
-## Run it with docker
+### As a Docker container
 
-Now godns supports to run in docker.
+With `/path/to/config.json` your local configuration file, run:
-
-* Get [config_sample.json](https://github.com/timothyye/godns/blob/master/config_sample.json) from Github.
-* Rename it to **config.json**.
-* Run GoDNS with docker:
 
 ```bash
-docker run -d --name godns --restart=always \
+docker run \
--v /path/to/config.json:/usr/local/godns/config.json timothyye/godns:latest
+-d --name godns --restart=always \
+-v /path/to/config.json:/config.json \
+timothyye/godns:latest
 ```
 
-## Run it as a Windows service
+### As a Windows service
 
-* Get [birkett/srvany-ng](https://github.com/birkett/srvany-ng/releases) from Github.
+1. Download the latest version of [NSSM](https://nssm.cc/download)
-* Uncompress and place the executable `srvany-ng.exe` to the same directory where `godns.exe` in.
-* Create a service and add registry keys according to the guide [here](https://github.com/birkett/srvany-ng).
 
-## Enjoy it!
+2. In an administrative prompt, from the folder where NSSM was downloaded, e.g. `C:\Downloads\nssm\` **win64**, run:
+
+   ```
+   nssm install YOURSERVICENAME
+   ```
+
+3. Follow the interface to configure the service. In the "Application" tab just indicate where the `godns.exe` file is. Optionally you can also define a description on the "Details" tab and define a log file on the "I/O" tab. Finish by clicking on the "Install service" button.
+
+4. The service will now start along Windows.
+
+Note: you can uninstall the service by running:
+
+```
+nssm remove YOURSERVICENAME
+```

-# Color [![GoDoc](https://godoc.org/github.com/fatih/color?status.svg)](https://godoc.org/github.com/fatih/color) [![Build Status](https://img.shields.io/travis/fatih/color.svg?style=flat-square)](https://travis-ci.org/fatih/color)
-
-
-
-Color lets you use colorized outputs in terms of [ANSI Escape
-Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
-has support for Windows too! The API can be used in several ways, pick one that
-suits you.
-
-
-![Color](https://i.imgur.com/c1JI0lA.png)
-
-
-## Install
-
-```bash
-go get github.com/fatih/color
-```
-
-Note that the `vendor` folder is here for stability. Remove the folder if you
-already have the dependencies in your GOPATH.
-
-## Examples
-
-### Standard colors
-
-```go
-// Print with default helper functions
-color.Cyan("Prints text in cyan.")
-
-// A newline will be appended automatically
-color.Blue("Prints %s in blue.", "text")
-
-// These are using the default foreground colors
-color.Red("We have red")
-color.Magenta("And many others ..")
-
-```
-
-### Mix and reuse colors
-
-```go
-// Create a new color object
-c := color.New(color.FgCyan).Add(color.Underline)
-c.Println("Prints cyan text with an underline.")
-
-// Or just add them to New()
-d := color.New(color.FgCyan, color.Bold)
-d.Printf("This prints bold cyan %s\n", "too!.")
-
-// Mix up foreground and background colors, create new mixes!
-red := color.New(color.FgRed)
-
-boldRed := red.Add(color.Bold)
-boldRed.Println("This will print text in bold red.")
-
-whiteBackground := red.Add(color.BgWhite)
-whiteBackground.Println("Red text with white background.")
-```
-
-### Use your own output (io.Writer)
-
-```go
-// Use your own io.Writer output
-color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-blue := color.New(color.FgBlue)
-blue.Fprint(writer, "This will print text in blue.")
-```
-
-### Custom print functions (PrintFunc)
-
-```go
-// Create a custom print function for convenience
-red := color.New(color.FgRed).PrintfFunc()
-red("Warning")
-red("Error: %s", err)
-
-// Mix up multiple attributes
-notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-notice("Don't forget this...")
-```
-
-### Custom fprint functions (FprintFunc)
-
-```go
-blue := color.New(FgBlue).FprintfFunc()
-blue(myWriter, "important notice: %s", stars)
-
-// Mix up with multiple attributes
-success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-success(myWriter, "Don't forget this...")
-```
-
-### Insert into noncolor strings (SprintFunc)
-
-```go
-// Create SprintXxx functions to mix strings with other non-colorized strings:
-yellow := color.New(color.FgYellow).SprintFunc()
-red := color.New(color.FgRed).SprintFunc()
-fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
-fmt.Printf("This %s rocks!\n", info("package"))
-
-// Use helper functions
-fmt.Println("This", color.RedString("warning"), "should be not neglected.")
-fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
-
-// Windows supported too! Just don't forget to change the output to color.Output
-fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-```
-
-### Plug into existing code
-
-```go
-// Use handy standard colors
-color.Set(color.FgYellow)
-
-fmt.Println("Existing text will now be in yellow")
-fmt.Printf("This one %s\n", "too")
-
-color.Unset() // Don't forget to unset
-
-// You can mix up parameters
-color.Set(color.FgMagenta, color.Bold)
-defer color.Unset() // Use it in your function
-
-fmt.Println("All text will now be bold magenta.")
-```
-
-### Disable/Enable color
- 
-There might be a case where you want to explicitly disable/enable color output. the 
-`go-isatty` package will automatically disable color output for non-tty output streams 
-(for example if the output were piped directly to `less`)
-
-`Color` has support to disable/enable colors both globally and for single color 
-definitions. For example suppose you have a CLI app and a `--no-color` bool flag. You 
-can easily disable the color output with:
-
-```go
-
-var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-if *flagNoColor {
-	color.NoColor = true // disables colorized output
-}
-```
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-```go
-c := color.New(color.FgCyan)
-c.Println("Prints cyan text")
-
-c.DisableColor()
-c.Println("This is printed without any color")
-
-c.EnableColor()
-c.Println("This prints again cyan...")
-```

-Package color is an ANSI color package to output colorized or SGR defined
-output to the standard output. The API can be used in several way, pick one
-that suits you.
-
-Use simple and default helper functions with predefined foreground colors:
-
-    color.Cyan("Prints text in cyan.")
-
-    // a newline will be appended automatically
-    color.Blue("Prints %s in blue.", "text")
-
-    // More default foreground colors..
-    color.Red("We have red")
-    color.Yellow("Yellow color too!")
-    color.Magenta("And many others ..")
-
-    // Hi-intensity colors
-    color.HiGreen("Bright green color.")
-    color.HiBlack("Bright black means gray..")
-    color.HiWhite("Shiny white color!")
-
-However there are times where custom color mixes are required. Below are some
-examples to create custom color objects and use the print functions of each
-separate color object.
-
-    // Create a new color object
-    c := color.New(color.FgCyan).Add(color.Underline)
-    c.Println("Prints cyan text with an underline.")
-
-    // Or just add them to New()
-    d := color.New(color.FgCyan, color.Bold)
-    d.Printf("This prints bold cyan %s\n", "too!.")
-
-
-    // Mix up foreground and background colors, create new mixes!
-    red := color.New(color.FgRed)
-
-    boldRed := red.Add(color.Bold)
-    boldRed.Println("This will print text in bold red.")
-
-    whiteBackground := red.Add(color.BgWhite)
-    whiteBackground.Println("Red text with White background.")
-
-    // Use your own io.Writer output
-    color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-    blue := color.New(color.FgBlue)
-    blue.Fprint(myWriter, "This will print text in blue.")
-
-You can create PrintXxx functions to simplify even more:
-
-    // Create a custom print function for convenient
-    red := color.New(color.FgRed).PrintfFunc()
-    red("warning")
-    red("error: %s", err)
-
-    // Mix up multiple attributes
-    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-    notice("don't forget this...")
-
-You can also FprintXxx functions to pass your own io.Writer:
-
-    blue := color.New(FgBlue).FprintfFunc()
-    blue(myWriter, "important notice: %s", stars)
-
-    // Mix up with multiple attributes
-    success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-    success(myWriter, don't forget this...")
-
-
-Or create SprintXxx functions to mix strings with other non-colorized strings:
-
-    yellow := New(FgYellow).SprintFunc()
-    red := New(FgRed).SprintFunc()
-
-    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Printf("this %s rocks!\n", info("package"))
-
-Windows support is enabled by default. All Print functions work as intended.
-However only for color.SprintXXX functions, user should use fmt.FprintXXX and
-set the output to color.Output:
-
-    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
-
-Using with existing code is possible. Just use the Set() method to set the
-standard output to the given parameters. That way a rewrite of an existing
-code is not required.
-
-    // Use handy standard colors.
-    color.Set(color.FgYellow)
-
-    fmt.Println("Existing text will be now in Yellow")
-    fmt.Printf("This one %s\n", "too")
-
-    color.Unset() // don't forget to unset
-
-    // You can mix up parameters
-    color.Set(color.FgMagenta, color.Bold)
-    defer color.Unset() // use it in your function
-
-    fmt.Println("All text will be now bold magenta.")
-
-There might be a case where you want to disable color output (for example to
-pipe the standard output of your app to somewhere else). `Color` has support to
-disable colors both globally and for single color definition. For example
-suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
-the color output with:
-
-    var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-    if *flagNoColor {
-    	color.NoColor = true // disables colorized output
-    }
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-     c := color.New(color.FgCyan)
-     c.Println("Prints cyan text")
-
-     c.DisableColor()
-     c.Println("This is printed without any color")
-
-     c.EnableColor()
-     c.Println("This prints again cyan...")

-For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
-This package is possible to handle escape sequence for ansi color on windows.

-# Building `sys/unix`
-
-The sys/unix package provides access to the raw system call interface of the
-underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
-
-Porting Go to a new architecture/OS combination or adding syscalls, types, or
-constants to an existing architecture/OS pair requires some manual effort;
-however, there are tools that automate much of the process.
-
-## Build Systems
-
-There are currently two ways we generate the necessary files. We are currently
-migrating the build system to use containers so the builds are reproducible.
-This is being done on an OS-by-OS basis. Please update this documentation as
-components of the build system change.
-
-### Old Build System (currently for `GOOS != "Linux" || GOARCH == "sparc64"`)
-
-The old build system generates the Go files based on the C header files
-present on your system. This means that files
-for a given GOOS/GOARCH pair must be generated on a system with that OS and
-architecture. This also means that the generated code can differ from system
-to system, based on differences in the header files.
-
-To avoid this, if you are using the old build system, only generate the Go
-files on an installation with unmodified header files. It is also important to
-keep track of which version of the OS the files were generated from (ex.
-Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
-and have each OS upgrade correspond to a single change.
-
-To build the files for your current OS and architecture, make sure GOOS and
-GOARCH are set correctly and run `mkall.sh`. This will generate the files for
-your specific system. Running `mkall.sh -n` shows the commands that will be run.
-
-Requirements: bash, perl, go
-
-### New Build System (currently for `GOOS == "Linux" && GOARCH != "sparc64"`)
-
-The new build system uses a Docker container to generate the go files directly
-from source checkouts of the kernel and various system libraries. This means
-that on any platform that supports Docker, all the files using the new build
-system can be generated at once, and generated files will not change based on
-what the person running the scripts has installed on their computer.
-
-The OS specific files for the new build system are located in the `${GOOS}`
-directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
-the kernel or system library updates, modify the Dockerfile at
-`${GOOS}/Dockerfile` to checkout the new release of the source.
-
-To build all the files under the new build system, you must be on an amd64/Linux
-system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
-then generate all of the files for all of the GOOS/GOARCH pairs in the new build
-system. Running `mkall.sh -n` shows the commands that will be run.
-
-Requirements: bash, perl, go, docker
-
-## Component files
-
-This section describes the various files used in the code generation process.
-It also contains instructions on how to modify these files to add a new
-architecture/OS or to add additional syscalls, types, or constants. Note that
-if you are using the new build system, the scripts cannot be called normally.
-They must be called from within the docker container.
-
-### asm files
-
-The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
-call dispatch. There are three entry points:
-```
-  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
-  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
-  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
-```
-The first and second are the standard ones; they differ only in how many
-arguments can be passed to the kernel. The third is for low-level use by the
-ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
-let it know that a system call is running.
-
-When porting Go to an new architecture/OS, this file must be implemented for
-each GOOS/GOARCH pair.
-
-### mksysnum
-
-Mksysnum is a script located at `${GOOS}/mksysnum.pl` (or `mksysnum_${GOOS}.pl`
-for the old system). This script takes in a list of header files containing the
-syscall number declarations and parses them to produce the corresponding list of
-Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
-constants.
-
-Adding new syscall numbers is mostly done by running the build on a sufficiently
-new installation of the target OS (or updating the source checkouts for the
-new build system). However, depending on the OS, you make need to update the
-parsing in mksysnum.
-
-### mksyscall.pl
-
-The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
-hand-written Go files which implement system calls (for unix, the specific OS,
-or the specific OS/Architecture pair respectively) that need special handling
-and list `//sys` comments giving prototypes for ones that can be generated.
-
-The mksyscall.pl script takes the `//sys` and `//sysnb` comments and converts
-them into syscalls. This requires the name of the prototype in the comment to
-match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
-prototype can be exported (capitalized) or not.
-
-Adding a new syscall often just requires adding a new `//sys` function prototype
-with the desired arguments and a capitalized name so it is exported. However, if
-you want the interface to the syscall to be different, often one will make an
-unexported `//sys` prototype, an then write a custom wrapper in
-`syscall_${GOOS}.go`.
-
-### types files
-
-For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
-`types_${GOOS}.go` on the old system). This file includes standard C headers and
-creates Go type aliases to the corresponding C types. The file is then fed
-through godef to get the Go compatible definitions. Finally, the generated code
-is fed though mkpost.go to format the code correctly and remove any hidden or
-private identifiers. This cleaned-up code is written to
-`ztypes_${GOOS}_${GOARCH}.go`.
-
-The hardest part about preparing this file is figuring out which headers to
-include and which symbols need to be `#define`d to get the actual data
-structures that pass through to the kernel system calls. Some C libraries
-preset alternate versions for binary compatibility and translate them on the
-way in and out of system calls, but there is almost always a `#define` that can
-get the real ones.
-See `types_darwin.go` and `linux/types.go` for examples.
-
-To add a new type, add in the necessary include statement at the top of the
-file (if it is not already there) and add in a type alias line. Note that if
-your type is significantly different on different architectures, you may need
-some `#if/#elif` macros in your include statements.
-
-### mkerrors.sh
-
-This script is used to generate the system's various constants. This doesn't
-just include the error numbers and error strings, but also the signal numbers
-an a wide variety of miscellaneous constants. The constants come from the list
-of include files in the `includes_${uname}` variable. A regex then picks out
-the desired `#define` statements, and generates the corresponding Go constants.
-The error numbers and strings are generated from `#include <errno.h>`, and the
-signal numbers and strings are generated from `#include <signal.h>`. All of
-these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
-`_errors.c`, which prints out all the constants.
-
-To add a constant, add the header that includes it to the appropriate variable.
-Then, edit the regex (if necessary) to match the desired constant. Avoid making
-the regex too broad to avoid matching unintended constants.
-
-
