-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# 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
-```

-// Marshal serializes the value provided into a YAML document. The structure
-// of the generated document will reflect the structure of the value itself.
-// Maps and pointers (to struct, string, int, etc) are accepted as the in value.
-//
-// Struct fields are only marshalled if they are exported (have an upper case
-// first letter), and are marshalled using the field name lowercased as the
-// default key. Custom keys may be defined via the "yaml" name in the field
-// tag: the content preceding the first comma is used as the key, and the
-// following comma-separated options are used to tweak the marshalling process.
-// Conflicting names result in a runtime error.
-//
-// The field tag format accepted is:
-//
-//     `(...) yaml:"[<key>][,<flag1>[,<flag2>]]" (...)`
-//
-// The following flags are currently supported:
-//
-//     omitempty    Only include the field if it's not set to the zero
-//                  value for the type or to empty slices or maps.
-//                  Zero valued structs will be omitted if all their public
-//                  fields are zero, unless they implement an IsZero
-//                  method (see the IsZeroer interface type), in which
-//                  case the field will be included if that method returns true.
-//
-//     flow         Marshal using a flow style (useful for structs,
-//                  sequences and maps).
-//
-//     inline       Inline the field, which must be a struct or a map,
-//                  causing all of its fields or keys to be processed as if
-//                  they were part of the outer struct. For maps, keys must
-//                  not conflict with the yaml keys of other struct fields.
-//
-// In addition, if the key is "-", the field is ignored.
-//
-// For example:
-//
-//     type T struct {
-//         F int `yaml:"a,omitempty"`
-//         B int
-//     }
-//     yaml.Marshal(&T{B: 2}) // Returns "b: 2\n"
-//     yaml.Marshal(&T{F: 1}} // Returns "a: 1\nb: 0\n"
