 =====
 Cepko implements easy-to-use communication with CloudSigma's VMs through a
 virtual serial port without bothering with formatting the messages properly nor
 parsing the output with the specific and sometimes confusing shell tools for
 that purpose.
 Having the server definition accessible by the VM can be useful in various
 ways. For example it is possible to easily determine from within the VM, which
 network interfaces are connected to public and which to private network.
 Another use is to pass some data to initial VM setup scripts, like setting the
 hostname to the VM name or passing ssh public keys through server meta.
 Example usage:
    package main
    import (
            "fmt"
            "github.com/cloudsigma/cepgo"
    )
    func main() {
            c := cepgo.NewCepgo()
            result, err := c.Meta()
            if err != nil {
                    panic(err)
            }
            fmt.Printf("%#v", result)
    }
 Output:
    map[string]interface {}{
        "optimize_for":"custom",
        "ssh_public_key":"ssh-rsa AAA...",
        "description":"[...]",

 GoSerial
 ========
 A simple go package to allow you to read and write from the
 serial port as a stream of bytes.
 Details
 -------
 It aims to have the same API on all platforms, including windows.  As
 an added bonus, the windows package does not use cgo, so you can cross
 compile for windows from another platform.  Unfortunately goinstall
 does not currently let you cross compile so you will have to do it
 manually:
    GOOS=windows make clean install
 Currently there is very little in the way of configurability.  You can
 set the baud rate.  Then you can Read(), Write(), or Close() the
 connection.  Read() will block until at least one byte is returned.
 Write is the same.  There is currently no exposed way to set the
 timeouts, though patches are welcome.
 Currently all ports are opened with 8 data bits, 1 stop bit, no
 parity, no hardware flow control, and no software flow control.  This
 works fine for many real devices and many faux serial devices
 including usb-to-serial converters and bluetooth serial ports.
 You may Read() and Write() simulantiously on the same connection (from
 different goroutines).
 Usage
 -----
 ```go
 package main
 import (
        "github.com/tarm/goserial"
        "log"
 )
 func main() {
        c := &serial.Config{Name: "COM45", Baud: 115200}
        s, err := serial.OpenPort(c)
        if err != nil {
                log.Fatal(err)
        }
        n, err := s.Write([]byte("test"))
        if err != nil {
                log.Fatal(err)
        }
        buf := make([]byte, 128)
        n, err = s.Read(buf)
        if err != nil {
                log.Fatal(err)
        }
        log.Print("%q", buf[:n])
 }
 ```
 Possible Future Work
 -------------------- 
 - better tests (loopback etc)

 /*
 Goserial is a simple go package to allow you to read and write from
 the serial port as a stream of bytes.
 It aims to have the same API on all platforms, including windows.  As
 an added bonus, the windows package does not use cgo, so you can cross
 compile for windows from another platform.  Unfortunately goinstall
 does not currently let you cross compile so you will have to do it
 manually:
 GOOS=windows make clean install
 Currently there is very little in the way of configurability.  You can
 set the baud rate.  Then you can Read(), Write(), or Close() the
 connection.  Read() will block until at least one byte is returned.
 Write is the same.  There is currently no exposed way to set the
 timeouts, though patches are welcome.
 Currently all ports are opened with 8 data bits, 1 stop bit, no
 parity, no hardware flow control, and no software flow control.  This
 works fine for many real devices and many faux serial devices
 including usb-to-serial converters and bluetooth serial ports.
 You may Read() and Write() simulantiously on the same connection (from
 different goroutines).
 Example usage:
  package main
  import (
        "github.com/tarm/goserial"
        "log"
  )
  func main() {
        c := &serial.Config{Name: "COM5", Baud: 115200}
        s, err := serial.OpenPort(c)
        if err != nil {
                log.Fatal(err)
        }
        n, err := s.Write([]byte("test"))
        if err != nil {
                log.Fatal(err)
        }
        buf := make([]byte, 128)
        n, err = s.Read(buf)
        if err != nil {
                log.Fatal(err)
        }
        log.Print("%q", buf[:n])
  }

 # YAML support for the Go language
 Introduction
 ------------
 The yaml package enables Go programs to comfortably encode and decode YAML
 values. It was developed within [Canonical](https://www.canonical.com) as
 part of the [juju](https://juju.ubuntu.com) project, and is based on a
 pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
 C library to parse and generate YAML data quickly and reliably.
 Compatibility
 -------------
 The yaml package is almost compatible with YAML 1.1, including support for
 anchors, tags, etc. There are still a few missing bits, such as document
 merging, base-60 floats (huh?), and multi-document unmarshalling. These
 features are not hard to add, and will be introduced as necessary.
 Installation and usage
 ----------------------
 The import path for the package is *gopkg.in/yaml.v1*.
 To install it, run:
    go get gopkg.in/yaml.v1
 API documentation
 -----------------
 If opened in a browser, the import path itself leads to the API documentation:
  * [https://gopkg.in/yaml.v1](https://gopkg.in/yaml.v1)
 API stability
 -------------
 The package API for yaml v1 will remain stable as described in [gopkg.in](https://gopkg.in).
 License
 -------
 The yaml package is licensed under the LGPL with an exception that allows it to be linked statically. Please see the LICENSE file for details.
 Example
 -------
 ```Go
 package main
 import (
        "fmt"
        "log"
        "gopkg.in/yaml.v1"
 )
 var data = `
 a: Easy!
 b:
  c: 2
  d: [3, 4]
 `
 type T struct {
        A string
        B struct{C int; D []int ",flow"}
 }
 func main() {
        t := T{}
        err := yaml.Unmarshal([]byte(data), &t)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- t:\n%v\n\n", t)
        d, err := yaml.Marshal(&t)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- t dump:\n%s\n\n", string(d))
        m := make(map[interface{}]interface{})
        err = yaml.Unmarshal([]byte(data), &m)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- m:\n%v\n\n", m)
        d, err = yaml.Marshal(&m)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- m dump:\n%s\n\n", string(d))
 }
 ```
 This example will generate the following output:
 ```
 --- t:
 {Easy! {2 [3 4]}}
 --- t dump:
 a: Easy!
 b:
  c: 2
  d: [3, 4]
 --- m:
 map[a:Easy! b:map[c:2 d:[3 4]]]
 --- m dump:
 a: Easy!
 b:
  c: 2
  d:
  - 3
  - 4

Jonathan Boulle	dfb5b4fc3a	initialize: use correct heuristic to check if etcdenvironment is set In some circumstances (e.g. nova-agent-watcher) cloudconfig files will be created where the EtcdEnvironment is an empty map, and hence != nil. If this is the case we should not do anything at all (because the user hasn't explicitly asked us to configure etcd). This change standardises behaviour with the check that we already do for FleetEnvironment.	2014-08-11 16:01:08 -07:00
