-Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
-2898 / PKCS #5 v2.0.
-
-A key derivation function is useful when encrypting data based on a password
-or any other not-fully-random data. It uses a pseudorandom function to derive
-a secure encryption key based on the password.
-
-While v2.0 of the standard defines only one pseudorandom function to use,
-HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
-Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
-choose, you can pass the `New` functions from the different SHA packages to
-pbkdf2.Key.

-//
-// For example, to use a HMAC-SHA-1 based PBKDF2 key derivation function, you

-# 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 supports most of YAML 1.1 and 1.2, including support for
-anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
-implemented, and base-60 floats from YAML 1.1 are purposefully not
-supported since they're a poor design and are gone in YAML 1.2.
-
-Installation and usage
-----------------------
-
-The import path for the package is *gopkg.in/yaml.v2*.
-
-To install it, run:
-
-    go get gopkg.in/yaml.v2
-
-API documentation
------------------
-
-If opened in a browser, the import path itself leads to the API documentation:
-
-  * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)
-
-API stability
--------------
-
-The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
-
-
-License
--------
-
-The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
-
-
-Example
--------
-
-```Go
-package main
-
-import (
-        "fmt"
-        "log"
-
-        "gopkg.in/yaml.v2"
-)
-
-var data = `
-a: Easy!
-b:
-  c: 2
-  d: [3, 4]
-`
-
-// Note: struct fields must be public in order for unmarshal to
-// correctly populate the data.
-type T struct {
-        A string
-        B struct {
-                RenamedC int   `yaml:"c"`
-                D        []int `yaml:",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
-```
