+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          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
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      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

+      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.
+

+go-log
+==========
+
+go-log is a simple logging library for Go which supports logging to
+systemd.
+
+### Examples
+#### Default
+This example uses the default log to log to standard out and (if available) to systemd:
+```go
+package main
+import (
+	"github.com/coreos/go-log/log"
+)
+
+func main() {
+	log.Info("Hello World.")
+	log.Error("There's nothing more to this program.")
+}
+```
+
+#### Using Sinks and Formats
+```go
+package main
+
+import (
+	"github.com/coreos/go-log/log"
+	"os"
+)
+
+func main() {
+	l := log.NewSimple(
+		log.WriterSink(os.Stderr,
+			"%s: %s[%d] %s\n",
+			[]string{"priority", "executable", "pid", "message"}))
+	l.Info("Here's a differently formatted log message.")
+}
+```
+
+#### Custom Sink
+This example only logs messages with priority `PriErr` and greater.
+```go
+package main
+
+import (
+	"github.com/coreos/go-log/log"
+	"os"
+)
+
+func main() {
+	l := log.NewSimple(
+		&PriorityFilter{
+			log.PriErr,
+			log.WriterSink(os.Stdout, log.BasicFormat, log.BasicFields),
+		})
+	l.Info("This will be filtered out")
+	l.Info("and not printed at all.")
+	l.Error("This will be printed, though!")
+	l.Critical("And so will this!")
+}
+
+type PriorityFilter struct {
+	priority log.Priority
+	target   log.Sink
+}
+
+func (filter *PriorityFilter) Log(fields log.Fields) {
+	// lower priority values indicate more important messages
+	if fields["priority"].(log.Priority) <= filter.priority {
+		filter.target.Log(fields)
+	}
+}
+```
+
+### Fields
+The following fields are available for use in all sinks:
+```go
+"prefix"       string              // static field available to all sinks
+"seq"          uint64              // auto-incrementing sequence number
+"start_time"   time.Time           // start time of the log
+"time"         string              // formatted time of log entry
+"full_time"    time.Time           // time of log entry
+"rtime"        time.Duration       // relative time of log entry since started
+"pid"          int                 // process id
+"executable"   string              // executable filename
+```
+In addition, if `verbose=true` is passed to `New()`, the following (somewhat expensive) runtime fields are also available:
+```go
+"funcname"     string              // function name where the log function was called
+"lineno"       int                 // line number where the log function was called
+"pathname"     string              // full pathname of caller
+"filename"     string              // filename of caller
+```
+
+### Logging functions
+All these functions can also be called directly to use the default log.
+```go
+func (*Logger) Log(priority Priority, v ...interface)
+func (*Logger) Logf(priority Priority, format string, v ...interface{})
+func (*Logger) Emergency(v ...interface)
+func (*Logger) Emergencyf(format string, v ...interface{})
+func (*Logger) Alert(v ...interface)
+func (*Logger) Alertf(format string, v ...interface{})
+func (*Logger) Critical(v ...interface)
+func (*Logger) Criticalf(format string, v ...interface{})
+func (*Logger) Error(v ...interface)
+func (*Logger) Errorf(format string, v ...interface{})
+func (*Logger) Warning(v ...interface)
+func (*Logger) Warningf(format string, v ...interface{})
+func (*Logger) Notice(v ...interface)
+func (*Logger) Noticef(format string, v ...interface{})
+func (*Logger) Info(v ...interface)
+func (*Logger) Infof(format string, v ...interface{})
+func (*Logger) Debug(v ...interface)
+func (*Logger) Debugf(format string, v ...interface{})
+```
+
+### Acknowledgements
+This package is a mostly-from-scratch rewrite of
+[ccding/go-logging](https://github.com/ccding/go-logging) with some features
+removed and systemd support added.

+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.

+# 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
+```
