-go-metrics
-==========
-
-This library provides a `metrics` package which can be used to instrument code,
-expose application metrics, and profile runtime performance in a flexible manner.
-
-Current API: [![GoDoc](https://godoc.org/github.com/armon/go-metrics?status.svg)](https://godoc.org/github.com/armon/go-metrics)
-
-Sinks
------
-
-The `metrics` package makes use of a `MetricSink` interface to support delivery
-to any type of backend. Currently the following sinks are provided:
-
-* StatsiteSink : Sinks to a [statsite](https://github.com/armon/statsite/) instance (TCP)
-* StatsdSink: Sinks to a [StatsD](https://github.com/etsy/statsd/) / statsite instance (UDP)
-* PrometheusSink: Sinks to a [Prometheus](http://prometheus.io/) metrics endpoint (exposed via HTTP for scrapes)
-* InmemSink : Provides in-memory aggregation, can be used to export stats
-* FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example.
-* BlackholeSink : Sinks to nowhere
-
-In addition to the sinks, the `InmemSignal` can be used to catch a signal,
-and dump a formatted output of recent metrics. For example, when a process gets
-a SIGUSR1, it can dump to stderr recent performance metrics for debugging.
-
-Labels
-------
-
-Most metrics do have an equivalent ending with `WithLabels`, such methods
-allow to push metrics with labels and use some features of underlying Sinks
-(ex: translated into Prometheus labels).
-
-Since some of these labels may increase greatly cardinality of metrics, the
-library allow to filter labels using a blacklist/whitelist filtering system
-which is global to all metrics.
-
-* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default.
-* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks.
-
-By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that
-no tags are filetered at all, but it allow to a user to globally block some tags with high
-cardinality at application level.
-
-Examples
---------
-
-Here is an example of using the package:
-
-```go
-func SlowMethod() {
-    // Profiling the runtime of a method
-    defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
-}
-
-// Configure a statsite sink as the global metrics sink
-sink, _ := metrics.NewStatsiteSink("statsite:8125")
-metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink)
-
-// Emit a Key/Value pair
-metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
-```
-
-Here is an example of setting up a signal handler:
-
-```go
-// Setup the inmem sink and signal handler
-inm := metrics.NewInmemSink(10*time.Second, time.Minute)
-sig := metrics.DefaultInmemSignal(inm)
-metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm)
-
-// Run some code
-inm.SetGauge([]string{"foo"}, 42)
-inm.EmitKey([]string{"bar"}, 30)
-
-inm.IncrCounter([]string{"baz"}, 42)
-inm.IncrCounter([]string{"baz"}, 1)
-inm.IncrCounter([]string{"baz"}, 80)
-
-inm.AddSample([]string{"method", "wow"}, 42)
-inm.AddSample([]string{"method", "wow"}, 100)
-inm.AddSample([]string{"method", "wow"}, 22)
-
-....
-```
-
-When a signal comes in, output like the following will be dumped to stderr:
-
-    [2014-01-28 14:57:33.04 -0800 PST][G] 'foo': 42.000
-    [2014-01-28 14:57:33.04 -0800 PST][P] 'bar': 30.000
-    [2014-01-28 14:57:33.04 -0800 PST][C] 'baz': Count: 3 Min: 1.000 Mean: 41.000 Max: 80.000 Stddev: 39.509
-    [2014-01-28 14:57:33.04 -0800 PST][S] 'method.wow': Count: 3 Min: 22.000 Mean: 54.667 Max: 100.000 Stddev: 40.513

-
-     a. under intellectual property rights (other than patent or trademark)
-        Licensable by such Contributor to use, reproduce, make available,
-        modify, display, perform, distribute, and otherwise exploit its
-        Contributions, either on an unmodified basis, with Modifications, or as

-        or its Contributor Version.
-
-2.2. Effective Date
-
-     The licenses granted in Section 2.1 with respect to any Contribution become
-     effective for each Contribution on the date the Contributor first distributes
-     such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under this
-     License. No additional rights or licenses will be implied from the distribution
-     or licensing of Covered Software under this License. Notwithstanding Section
-     2.1(b) above, no patent license is granted by a Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party’s
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of its
-        Contributions.
-
-     This License does not grant any rights in the trademarks, service marks, or
-     logos of any Contributor (except as may be necessary to comply with the
-     notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this License
-     (see Section 10.2) or under the terms of a Secondary License (if permitted
-     under the terms of Section 3.3).
-
-2.5. Representation
-
-     Each Contributor represents that the Contributor believes its Contributions
-     are its original creation(s) or it has sufficient rights to grant the
-     rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-     This License is not intended to limit any rights You have under applicable
-     copyright doctrines of fair use, fair dealing, or other equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under the
-     terms of this License. You must inform recipients that the Source Code Form
-     of the Covered Software is governed by the terms of this License, and how
-     they can obtain a copy of this License. You may not attempt to alter or
-     restrict the recipients’ rights in the Source Code Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this License,
-        or sublicense it under different terms, provided that the license for
-        the Executable Form does not attempt to limit or alter the recipients’
-        rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for the
-     Covered Software. If the Larger Work is a combination of Covered Software
-     with a work governed by one or more Secondary Licenses, and the Covered
-     Software is not Incompatible With Secondary Licenses, this License permits
-     You to additionally distribute such Covered Software under the terms of
-     such Secondary License(s), so that the recipient of the Larger Work may, at
-     their option, further distribute the Covered Software under the terms of
-     either this License or such Secondary License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices (including
-     copyright notices, patent notices, disclaimers of warranty, or limitations
-     of liability) contained within the Source Code Form of the Covered
-     Software, except that You may alter any license notices to the extent
-     required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on behalf
-     of any Contributor. You must make it absolutely clear that any such
-     warranty, support, indemnity, or liability obligation is offered by You
-     alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute, judicial
-   order, or regulation then You must: (a) comply with the terms of this License
-   to the maximum extent possible; and (b) describe the limitations and the code
-   they affect. Such description must be placed in a text file included with all
-   distributions of the Covered Software under this License. Except to the
-   extent prohibited by statute or regulation, such description must be
-   sufficiently detailed for a recipient of ordinary skill to be able to
-   understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
-     if such Contributor fails to notify You of the non-compliance by some
-     reasonable means prior to 60 days after You have come back into compliance.
-     Moreover, Your grants from a particular Contributor are reinstated on an
-     ongoing basis if such Contributor notifies You of the non-compliance by
-     some reasonable means, this is the first time You have received notice of
-     non-compliance with this License from such Contributor, and You become
-     compliant prior to 30 days after Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions, counter-claims,
-     and cross-claims) alleging that a Contributor Version directly or
-     indirectly infringes any patent, then the rights granted to You by any and
-     all Contributors for the Covered Software under Section 2.1 of this License
-     shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an “as is” basis, without
-   warranty of any kind, either expressed, implied, or statutory, including,
-   without limitation, warranties that the Covered Software is free of defects,
-   merchantable, fit for a particular purpose or non-infringing. The entire
-   risk as to the quality and performance of the Covered Software is with You.
-   Should any Covered Software prove defective in any respect, You (not any
-   Contributor) assume the cost of any necessary servicing, repair, or
-   correction. This disclaimer of warranty constitutes an essential part of this
-   License. No use of  any Covered Software is authorized under this License
-   except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from such
-   party’s negligence to the extent applicable law prohibits such limitation.
-   Some jurisdictions do not allow the exclusion or limitation of incidental or
-   consequential damages, so this exclusion and limitation may not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts of
-   a jurisdiction where the defendant maintains its principal place of business
-   and such litigation shall be governed by laws of that jurisdiction, without
-   reference to its conflict-of-law provisions. Nothing in this Section shall
-   prevent a party’s ability to bring cross-claims or counter-claims.
-

-Consul API client
-=================
-
-This package provides the `api` package which attempts to
-provide programmatic access to the full Consul API.
-
-Currently, all of the Consul APIs included in version 0.6.0 are supported.
-
-Documentation
-=============
-
-The full documentation is available on [Godoc](https://godoc.org/github.com/hashicorp/consul/api)
-
-Usage
-=====
-
-Below is an example of using the Consul client:
-
-```go
-package main
-
-import "github.com/hashicorp/consul/api"
-import "fmt"
-
-func main() {
-	// Get a new client
-	client, err := api.NewClient(api.DefaultConfig())
-	if err != nil {
-		panic(err)
-	}
-
-	// Get a handle to the KV API
-	kv := client.KV()
-
-	// PUT a new KV pair
-	p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
-	_, err = kv.Put(p, nil)
-	if err != nil {
-		panic(err)
-	}
-
-	// Lookup the pair
-	pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
-	if err != nil {
-		panic(err)
-	}
-	fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
-}
-```
-
-To run this example, start a Consul server:
-
-```bash
-consul agent -dev
-```
-
-Copy the code above into a file such as `main.go`.
-
-Install and run. You'll see a key (`REDIS_MAXCLIENTS`) and value (`1000`) printed.
-
-```bash
-$ go get
-$ go run main.go
-KV: REDIS_MAXCLIENTS 1000
-```
-
-After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv

-// consistency controls, but not blocking. If there are write operations then
-// the request will always be routed through raft and any consistency settings
-// will be ignored.
-//
-// Here's an example:
-//
-//	   ops := KVTxnOps{
-//		   &KVTxnOp{
-//			   Verb:    KVLock,
-//			   Key:     "test/lock",

-// If there is a problem making the transaction request then an error will be
-// returned. Otherwise, the ok value will be true if the transaction succeeded
-// or false if it was rolled back. The response is a structured return value which
-// will have the outcome of the transaction. Its Results member will have entries
-// for each operation. For KV operations, Deleted keys will have a nil entry in the
-// results, and to save space, the Value of each key in the Results will be nil
-// unless the operation is a KVGet. If the transaction was rolled back, the Errors

-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under
-     the terms of this License. You must inform recipients that the Source
-     Code Form of the Covered Software is governed by the terms of this
-     License, and how they can obtain a copy of this License. You may not
-     attempt to alter or restrict the recipients' rights in the Source Code
-     Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this
-        License, or sublicense it under different terms, provided that the
-        license for the Executable Form does not attempt to limit or alter the
-        recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for
-     the Covered Software. If the Larger Work is a combination of Covered
-     Software with a work governed by one or more Secondary Licenses, and the
-     Covered Software is not Incompatible With Secondary Licenses, this
-     License permits You to additionally distribute such Covered Software
-     under the terms of such Secondary License(s), so that the recipient of
-     the Larger Work may, at their option, further distribute the Covered
-     Software under the terms of either this License or such Secondary
-     License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices
-     (including copyright notices, patent notices, disclaimers of warranty, or
-     limitations of liability) contained within the Source Code Form of the
-     Covered Software, except that You may alter any license notices to the
-     extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on
-     behalf of any Contributor. You must make it absolutely clear that any
-     such warranty, support, indemnity, or liability obligation is offered by
-     You alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute,
-   judicial order, or regulation then You must: (a) comply with the terms of
-   this License to the maximum extent possible; and (b) describe the
-   limitations and the code they affect. Such description must be placed in a
-   text file included with all distributions of the Covered Software under
-   this License. Except to the extent prohibited by statute or regulation,
-   such description must be sufficiently detailed for a recipient of ordinary
-   skill to be able to understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing
-     basis, if such Contributor fails to notify You of the non-compliance by
-     some reasonable means prior to 60 days after You have come back into
-     compliance. Moreover, Your grants from a particular Contributor are
-     reinstated on an ongoing basis if such Contributor notifies You of the
-     non-compliance by some reasonable means, this is the first time You have
-     received notice of non-compliance with this License from such
-     Contributor, and You become compliant prior to 30 days after Your receipt
-     of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions,
-     counter-claims, and cross-claims) alleging that a Contributor Version
-     directly or indirectly infringes any patent, then the rights granted to
-     You by any and all Contributors for the Covered Software under Section
-     2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an "as is" basis,
-   without warranty of any kind, either expressed, implied, or statutory,
-   including, without limitation, warranties that the Covered Software is free
-   of defects, merchantable, fit for a particular purpose or non-infringing.
-   The entire risk as to the quality and performance of the Covered Software
-   is with You. Should any Covered Software prove defective in any respect,
-   You (not any Contributor) assume the cost of any necessary servicing,
-   repair, or correction. This disclaimer of warranty constitutes an essential
-   part of this License. No use of  any Covered Software is authorized under
-   this License except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from
-   such party's negligence to the extent applicable law prohibits such
-   limitation. Some jurisdictions do not allow the exclusion or limitation of
-   incidental or consequential damages, so this exclusion and limitation may
-   not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts
-   of a jurisdiction where the defendant maintains its principal place of
-   business and such litigation shall be governed by laws of that
-   jurisdiction, without reference to its conflict-of-law provisions. Nothing
-   in this Section shall prevent a party's ability to bring cross-claims or
-   counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject
-   matter hereof. If any provision of this License is held to be
-   unenforceable, such provision shall be reformed only to the extent
-   necessary to make it enforceable. Any law or regulation which provides that
-   the language of a contract shall be construed against the drafter shall not
-   be used to construe this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or

-Functions for accessing "clean" Go http.Client values
-
--------------
-
-The Go standard library contains a default `http.Client` called
-`http.DefaultClient`. It is a common idiom in Go code to start with
-`http.DefaultClient` and tweak it as necessary, and in fact, this is
-encouraged; from the `http` package documentation:
-
-> The Client's Transport typically has internal state (cached TCP connections),
-so Clients should be reused instead of created as needed. Clients are safe for
-concurrent use by multiple goroutines.
-
-Unfortunately, this is a shared value, and it is not uncommon for libraries to
-assume that they are free to modify it at will. With enough dependencies, it
-can be very easy to encounter strange problems and race conditions due to
-manipulation of this shared value across libraries and goroutines (clients are
-safe for concurrent use, but writing values to the client struct itself is not
-protected).
-
-Making things worse is the fact that a bare `http.Client` will use a default
-`http.Transport` called `http.DefaultTransport`, which is another global value
-that behaves the same way. So it is not simply enough to replace
-`http.DefaultClient` with `&http.Client{}`.
-
-This repository provides some simple functions to get a "clean" `http.Client`
--- one that uses the same default values as the Go standard library, but
-returns a client that does not share any state with other clients.

-     distributes such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under
-     this License. No additional rights or licenses will be implied from the
-     distribution or licensing of Covered Software under this License.
-     Notwithstanding Section 2.1(b) above, no patent license is granted by a

-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of
-        its Contributions.
-
-     This License does not grant any rights in the trademarks, service marks,
-     or logos of any Contributor (except as may be necessary to comply with
-     the notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this
-     License (see Section 10.2) or under the terms of a Secondary License (if
-     permitted under the terms of Section 3.3).
-
-2.5. Representation

-     equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under
-     the terms of this License. You must inform recipients that the Source
-     Code Form of the Covered Software is governed by the terms of this
-     License, and how they can obtain a copy of this License. You may not
-     attempt to alter or restrict the recipients' rights in the Source Code
-     Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this
-        License, or sublicense it under different terms, provided that the
-        license for the Executable Form does not attempt to limit or alter the
-        recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for
-     the Covered Software. If the Larger Work is a combination of Covered
-     Software with a work governed by one or more Secondary Licenses, and the
-     Covered Software is not Incompatible With Secondary Licenses, this
-     License permits You to additionally distribute such Covered Software
-     under the terms of such Secondary License(s), so that the recipient of
-     the Larger Work may, at their option, further distribute the Covered
-     Software under the terms of either this License or such Secondary
-     License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices
-     (including copyright notices, patent notices, disclaimers of warranty, or
-     limitations of liability) contained within the Source Code Form of the
-     Covered Software, except that You may alter any license notices to the
-     extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on
-     behalf of any Contributor. You must make it absolutely clear that any
-     such warranty, support, indemnity, or liability obligation is offered by
-     You alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute,
-   judicial order, or regulation then You must: (a) comply with the terms of
-   this License to the maximum extent possible; and (b) describe the
-   limitations and the code they affect. Such description must be placed in a
-   text file included with all distributions of the Covered Software under
-   this License. Except to the extent prohibited by statute or regulation,
-   such description must be sufficiently detailed for a recipient of ordinary
-   skill to be able to understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing
-     basis, if such Contributor fails to notify You of the non-compliance by
-     some reasonable means prior to 60 days after You have come back into
-     compliance. Moreover, Your grants from a particular Contributor are
-     reinstated on an ongoing basis if such Contributor notifies You of the
-     non-compliance by some reasonable means, this is the first time You have
-     received notice of non-compliance with this License from such
-     Contributor, and You become compliant prior to 30 days after Your receipt
-     of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions,
-     counter-claims, and cross-claims) alleging that a Contributor Version
-     directly or indirectly infringes any patent, then the rights granted to
-     You by any and all Contributors for the Covered Software under Section
-     2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an "as is" basis,
-   without warranty of any kind, either expressed, implied, or statutory,
-   including, without limitation, warranties that the Covered Software is free
-   of defects, merchantable, fit for a particular purpose or non-infringing.
-   The entire risk as to the quality and performance of the Covered Software
-   is with You. Should any Covered Software prove defective in any respect,
-   You (not any Contributor) assume the cost of any necessary servicing,
-   repair, or correction. This disclaimer of warranty constitutes an essential
-   part of this License. No use of  any Covered Software is authorized under
-   this License except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from
-   such party's negligence to the extent applicable law prohibits such
-   limitation. Some jurisdictions do not allow the exclusion or limitation of
-   incidental or consequential damages, so this exclusion and limitation may
-   not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts
-   of a jurisdiction where the defendant maintains its principal place of
-   business and such litigation shall be governed by laws of that
-   jurisdiction, without reference to its conflict-of-law provisions. Nothing
-   in this Section shall prevent a party's ability to bring cross-claims or
-   counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject
-   matter hereof. If any provision of this License is held to be
-   unenforceable, such provision shall be reformed only to the extent
-   necessary to make it enforceable. Any law or regulation which provides that
-   the language of a contract shall be construed against the drafter shall not
-   be used to construe this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version
-      of the License under which You originally received the Covered Software,
-      or under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a
-      modified version of this License if you rename the license and remove
-      any references to the name of the license steward (except to note that
-      such modified license differs from this License).
-
-10.4. Distributing Source Code Form that is Incompatible With Secondary
-      Licenses If You choose to distribute Source Code Form that is
-      Incompatible With Secondary Licenses under the terms of this version of
-      the License, the notice described in Exhibit B of this License must be
-      attached.
-

-go-immutable-radix [![Build Status](https://travis-ci.org/hashicorp/go-immutable-radix.png)](https://travis-ci.org/hashicorp/go-immutable-radix)
-=========
-
-Provides the `iradix` package that implements an immutable [radix tree](http://en.wikipedia.org/wiki/Radix_tree).
-The package only provides a single `Tree` implementation, optimized for sparse nodes.
-
-As a radix tree, it provides the following:
- * O(k) operations. In many cases, this can be faster than a hash table since
-   the hash function is an O(k) operation, and hash tables have very poor cache locality.
- * Minimum / Maximum value lookups
- * Ordered iteration
-
-A tree supports using a transaction to batch multiple updates (insert, delete)
-in a more efficient manner than performing each operation one at a time.
-
-For a mutable variant, see [go-radix](https://github.com/armon/go-radix).
-
-Documentation
-=============
-
-The full documentation is available on [Godoc](http://godoc.org/github.com/hashicorp/go-immutable-radix).
-
-Example
-=======
-
-Below is a simple example of usage
-
-```go
-// Create a tree
-r := iradix.New()
-r, _, _ = r.Insert([]byte("foo"), 1)
-r, _, _ = r.Insert([]byte("bar"), 2)
-r, _, _ = r.Insert([]byte("foobar"), 2)
-
-// Find the longest prefix match
-m, _, _ := r.Root().LongestPrefix([]byte("foozip"))
-if string(m) != "foo" {
-    panic("should be foo")
-}
-```
-
-Here is an example of performing a range scan of the keys.
-
-```go
-// Create a tree
-r := iradix.New()
-r, _, _ = r.Insert([]byte("001"), 1)
-r, _, _ = r.Insert([]byte("002"), 2)
-r, _, _ = r.Insert([]byte("005"), 5)
-r, _, _ = r.Insert([]byte("010"), 10)
-r, _, _ = r.Insert([]byte("100"), 10)
-
-// Range scan over the keys that sort lexicographically between [003, 050)
-it := r.Root().Iterator()
-it.SeekLowerBound([]byte("003"))
-for key, _, ok := it.Next(); ok; key, _, ok = it.Next() {
-  if key >= "050" {
-      break
-  }
-  fmt.Println(key)
-}
-// Output:
-//  005
-//  010
-```

-     distributes such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under
-     this License. No additional rights or licenses will be implied from the
-     distribution or licensing of Covered Software under this License.
-     Notwithstanding Section 2.1(b) above, no patent license is granted by a
-     Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party's
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of
-        its Contributions.
-
-     This License does not grant any rights in the trademarks, service marks,
-     or logos of any Contributor (except as may be necessary to comply with
-     the notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this
-     License (see Section 10.2) or under the terms of a Secondary License (if
-     permitted under the terms of Section 3.3).
-

-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under
-     the terms of this License. You must inform recipients that the Source
-     Code Form of the Covered Software is governed by the terms of this
-     License, and how they can obtain a copy of this License. You may not
-     attempt to alter or restrict the recipients' rights in the Source Code
-     Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this
-        License, or sublicense it under different terms, provided that the
-        license for the Executable Form does not attempt to limit or alter the
-        recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for
-     the Covered Software. If the Larger Work is a combination of Covered
-     Software with a work governed by one or more Secondary Licenses, and the
-     Covered Software is not Incompatible With Secondary Licenses, this
-     License permits You to additionally distribute such Covered Software
-     under the terms of such Secondary License(s), so that the recipient of
-     the Larger Work may, at their option, further distribute the Covered
-     Software under the terms of either this License or such Secondary
-     License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices
-     (including copyright notices, patent notices, disclaimers of warranty, or
-     limitations of liability) contained within the Source Code Form of the
-     Covered Software, except that You may alter any license notices to the
-     extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on
-     behalf of any Contributor. You must make it absolutely clear that any
-     such warranty, support, indemnity, or liability obligation is offered by
-     You alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute,
-   judicial order, or regulation then You must: (a) comply with the terms of
-   this License to the maximum extent possible; and (b) describe the
-   limitations and the code they affect. Such description must be placed in a
-   text file included with all distributions of the Covered Software under
-   this License. Except to the extent prohibited by statute or regulation,
-   such description must be sufficiently detailed for a recipient of ordinary
-   skill to be able to understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing
-     basis, if such Contributor fails to notify You of the non-compliance by
-     some reasonable means prior to 60 days after You have come back into
-     compliance. Moreover, Your grants from a particular Contributor are
-     reinstated on an ongoing basis if such Contributor notifies You of the
-     non-compliance by some reasonable means, this is the first time You have
-     received notice of non-compliance with this License from such
-     Contributor, and You become compliant prior to 30 days after Your receipt
-     of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions,
-     counter-claims, and cross-claims) alleging that a Contributor Version
-     directly or indirectly infringes any patent, then the rights granted to
-     You by any and all Contributors for the Covered Software under Section
-     2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an "as is" basis,
-   without warranty of any kind, either expressed, implied, or statutory,
-   including, without limitation, warranties that the Covered Software is free
-   of defects, merchantable, fit for a particular purpose or non-infringing.
-   The entire risk as to the quality and performance of the Covered Software
-   is with You. Should any Covered Software prove defective in any respect,
-   You (not any Contributor) assume the cost of any necessary servicing,
-   repair, or correction. This disclaimer of warranty constitutes an essential
-   part of this License. No use of  any Covered Software is authorized under
-   this License except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from

-# rootcerts
-
-Functions for loading root certificates for TLS connections.
-
------
-
-Go's standard library `crypto/tls` provides a common mechanism for configuring
-TLS connections in `tls.Config`. The `RootCAs` field on this struct is a pool
-of certificates for the client to use as a trust store when verifying server
-certificates.
-
-This library contains utility functions for loading certificates destined for
-that field, as well as one other important thing:
-
-When the `RootCAs` field is `nil`, the standard library attempts to load the
-host's root CA set.  This behavior is OS-specific, and the Darwin
-implementation contains [a bug that prevents trusted certificates from the
-System and Login keychains from being loaded][1]. This library contains
-Darwin-specific behavior that works around that bug.
-
-[1]: https://github.com/golang/go/issues/14514
-
-## Example Usage
-
-Here's a snippet demonstrating how this library is meant to be used:
-
-```go
-func httpClient() (*http.Client, error)
-	tlsConfig := &tls.Config{}
-	err := rootcerts.ConfigureTLS(tlsConfig, &rootcerts.Config{
-		CAFile: os.Getenv("MYAPP_CAFILE"),
-		CAPath: os.Getenv("MYAPP_CAPATH"),
-	})
-	if err != nil {
-		return nil, err
-	}
-	c := cleanhttp.DefaultClient()
-	t := cleanhttp.DefaultTransport()
-	t.TLSClientConfig = tlsConfig
-	c.Transport = t
-	return c, nil
-}
-```

-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under
-     the terms of this License. You must inform recipients that the Source
-     Code Form of the Covered Software is governed by the terms of this
-     License, and how they can obtain a copy of this License. You may not
-     attempt to alter or restrict the recipients' rights in the Source Code
-     Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this
-        License, or sublicense it under different terms, provided that the
-        license for the Executable Form does not attempt to limit or alter the
-        recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for
-     the Covered Software. If the Larger Work is a combination of Covered
-     Software with a work governed by one or more Secondary Licenses, and the
-     Covered Software is not Incompatible With Secondary Licenses, this
-     License permits You to additionally distribute such Covered Software
-     under the terms of such Secondary License(s), so that the recipient of
-     the Larger Work may, at their option, further distribute the Covered
-     Software under the terms of either this License or such Secondary
-     License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices
-     (including copyright notices, patent notices, disclaimers of warranty, or
-     limitations of liability) contained within the Source Code Form of the
-     Covered Software, except that You may alter any license notices to the
-     extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on
-     behalf of any Contributor. You must make it absolutely clear that any
-     such warranty, support, indemnity, or liability obligation is offered by
-     You alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute,
-   judicial order, or regulation then You must: (a) comply with the terms of
-   this License to the maximum extent possible; and (b) describe the
-   limitations and the code they affect. Such description must be placed in a
-   text file included with all distributions of the Covered Software under
-   this License. Except to the extent prohibited by statute or regulation,
-   such description must be sufficiently detailed for a recipient of ordinary
-   skill to be able to understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing
-     basis, if such Contributor fails to notify You of the non-compliance by
-     some reasonable means prior to 60 days after You have come back into
-     compliance. Moreover, Your grants from a particular Contributor are
-     reinstated on an ongoing basis if such Contributor notifies You of the
-     non-compliance by some reasonable means, this is the first time You have
-     received notice of non-compliance with this License from such
-     Contributor, and You become compliant prior to 30 days after Your receipt
-     of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions,
-     counter-claims, and cross-claims) alleging that a Contributor Version
-     directly or indirectly infringes any patent, then the rights granted to
-     You by any and all Contributors for the Covered Software under Section
-     2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an "as is" basis,
-   without warranty of any kind, either expressed, implied, or statutory,
-   including, without limitation, warranties that the Covered Software is free
-   of defects, merchantable, fit for a particular purpose or non-infringing.
-   The entire risk as to the quality and performance of the Covered Software
-   is with You. Should any Covered Software prove defective in any respect,
-   You (not any Contributor) assume the cost of any necessary servicing,
-   repair, or correction. This disclaimer of warranty constitutes an essential
-   part of this License. No use of  any Covered Software is authorized under
-   this License except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from
-   such party's negligence to the extent applicable law prohibits such
-   limitation. Some jurisdictions do not allow the exclusion or limitation of
-   incidental or consequential damages, so this exclusion and limitation may
-   not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts
-   of a jurisdiction where the defendant maintains its principal place of
-   business and such litigation shall be governed by laws of that
-   jurisdiction, without reference to its conflict-of-law provisions. Nothing
-   in this Section shall prevent a party's ability to bring cross-claims or
-   counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject
-   matter hereof. If any provision of this License is held to be
-   unenforceable, such provision shall be reformed only to the extent
-   necessary to make it enforceable. Any law or regulation which provides that
-   the language of a contract shall be construed against the drafter shall not
-   be used to construe this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions

-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or

-      distinguishing version number.
-
-10.2. Effect of New Versions

-      or under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a
-      modified version of this License if you rename the license and remove
-      any references to the name of the license steward (except to note that
-      such modified license differs from this License).

-
-     The licenses granted in this Section 2 are the only rights granted under this
-     License. No additional rights or licenses will be implied from the distribution

-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of its
-        Contributions.
-
-     This License does not grant any rights in the trademarks, service marks, or
-     logos of any Contributor (except as may be necessary to comply with the
-     notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this License
-     (see Section 10.2) or under the terms of a Secondary License (if permitted
-     under the terms of Section 3.3).
-

-     are its original creation(s) or it has sufficient rights to grant the
-     rights to its Contributions conveyed by this License.

-
-     This License is not intended to limit any rights You have under applicable

-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under the
-     terms of this License. You must inform recipients that the Source Code Form
-     of the Covered Software is governed by the terms of this License, and how
-     they can obtain a copy of this License. You may not attempt to alter or
-     restrict the recipients’ rights in the Source Code Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this License,
-        or sublicense it under different terms, provided that the license for
-        the Executable Form does not attempt to limit or alter the recipients’
-        rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for the
-     Covered Software. If the Larger Work is a combination of Covered Software
-     with a work governed by one or more Secondary Licenses, and the Covered
-     Software is not Incompatible With Secondary Licenses, this License permits
-     You to additionally distribute such Covered Software under the terms of
-     such Secondary License(s), so that the recipient of the Larger Work may, at
-     their option, further distribute the Covered Software under the terms of
-     either this License or such Secondary License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices (including
-     copyright notices, patent notices, disclaimers of warranty, or limitations
-     of liability) contained within the Source Code Form of the Covered
-     Software, except that You may alter any license notices to the extent
-     required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on behalf
-     of any Contributor. You must make it absolutely clear that any such
-     warranty, support, indemnity, or liability obligation is offered by You
-     alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute, judicial
-   order, or regulation then You must: (a) comply with the terms of this License
-   to the maximum extent possible; and (b) describe the limitations and the code
-   they affect. Such description must be placed in a text file included with all
-   distributions of the Covered Software under this License. Except to the
-   extent prohibited by statute or regulation, such description must be
-   sufficiently detailed for a recipient of ordinary skill to be able to
-   understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
-     if such Contributor fails to notify You of the non-compliance by some
-     reasonable means prior to 60 days after You have come back into compliance.
-     Moreover, Your grants from a particular Contributor are reinstated on an
-     ongoing basis if such Contributor notifies You of the non-compliance by
-     some reasonable means, this is the first time You have received notice of
-     non-compliance with this License from such Contributor, and You become
-     compliant prior to 30 days after Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions, counter-claims,
-     and cross-claims) alleging that a Contributor Version directly or
-     indirectly infringes any patent, then the rights granted to You by any and
-     all Contributors for the Covered Software under Section 2.1 of this License
-     shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an “as is” basis, without
-   warranty of any kind, either expressed, implied, or statutory, including,
-   without limitation, warranties that the Covered Software is free of defects,
-   merchantable, fit for a particular purpose or non-infringing. The entire
-   risk as to the quality and performance of the Covered Software is with You.
-   Should any Covered Software prove defective in any respect, You (not any
-   Contributor) assume the cost of any necessary servicing, repair, or
-   correction. This disclaimer of warranty constitutes an essential part of this
-   License. No use of  any Covered Software is authorized under this License
-   except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from such
-   party’s negligence to the extent applicable law prohibits such limitation.
-   Some jurisdictions do not allow the exclusion or limitation of incidental or
-   consequential damages, so this exclusion and limitation may not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts of
-   a jurisdiction where the defendant maintains its principal place of business
-   and such litigation shall be governed by laws of that jurisdiction, without
-   reference to its conflict-of-law provisions. Nothing in this Section shall
-   prevent a party’s ability to bring cross-claims or counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject matter
-   hereof. If any provision of this License is held to be unenforceable, such
-   provision shall be reformed only to the extent necessary to make it
-   enforceable. Any law or regulation which provides that the language of a
-   contract shall be construed against the drafter shall not be used to construe
-   this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version of
-      the License under which You originally received the Covered Software, or
-      under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-

-# go-homedir
-
-This is a Go library for detecting the user's home directory without
-the use of cgo, so the library can be used in cross-compilation environments.
-
-Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
-for a user, and `homedir.Expand()` to expand the `~` in a path to the home
-directory.
-
-**Why not just use `os/user`?** The built-in `os/user` package requires
-cgo on Darwin systems. This means that any Go code that uses that package
-cannot cross compile. But 99% of the time the use for `os/user` is just to
-retrieve the home directory, which we can do for the current user without
-cgo. This library does that, enabling cross-compilation.

-# mapstructure [![Godoc](https://godoc.org/github.com/mitchellh/mapstructure?status.svg)](https://godoc.org/github.com/mitchellh/mapstructure)
-
-mapstructure is a Go library for decoding generic map values to structures
-and vice versa, while providing helpful error handling.
-
-This library is most useful when decoding values from some data stream (JSON,
-Gob, etc.) where you don't _quite_ know the structure of the underlying data
-until you read a part of it. You can therefore read a `map[string]interface{}`
-and use this library to decode it into the proper underlying native Go
-structure.
-
-## Installation
-
-Standard `go get`:
-
-```
-$ go get github.com/mitchellh/mapstructure
-```
-
-## Usage & Example
-
-For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
-
-The `Decode` function has examples associated with it there.
-
-## But Why?!
-
-Go offers fantastic standard libraries for decoding formats such as JSON.
-The standard method is to have a struct pre-created, and populate that struct
-from the bytes of the encoded format. This is great, but the problem is if
-you have configuration or an encoding that changes slightly depending on
-specific fields. For example, consider this JSON:
-
-```json
-{
-  "type": "person",
-  "name": "Mitchell"
-}
-```
-
-Perhaps we can't populate a specific structure without first reading
-the "type" field from the JSON. We could always do two passes over the
-decoding of the JSON (reading the "type" first, and the rest later).
-However, it is much simpler to just decode this into a `map[string]interface{}`
-structure, read the "type" key, then use something like this library
-to decode it into the proper structure.
