build: Add missing region attribute for uploads

### Purpose

Avoid the issue where the folder marker is deleted by overzealous
cleanup tools because it's just a useless, empty directory.

We create a small file containing a an admonishment to not delete the
directory, and some metadata that is just for human consumption at the
moment. (But it would parse as a valid yaml file if we wanted to read
this, at some point.)

This will only apply when _creating_ a folder marker, that is, existing
setups will not gain the file automatically. Obviously, when using a
custom folder marker none of this applies.

Also, slightly adjust the permission bits for the folder marker directory and file on Unixes, making sure the group & write bits are unset.

### Testing

I've created and deleted a few folders and it appears to behave as I
expect.

### Screenshots

-## Conduct
+# Contributor Covenant Code of Conduct
 
-* We are committed to providing a friendly, safe and welcoming
-  environment for all, regardless of gender, sexual orientation,
-  disability, ethnicity, religion, or similar personal characteristic.
+## Our Pledge
 
-* On IRC, please avoid using overtly sexual nicknames or other nicknames
-  that might detract from a friendly, safe and welcoming environment for
-  all.
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+education, socio-economic status, nationality, personal appearance, race,
+religion, or sexual identity and orientation.
 
-* Please be kind and courteous. There's no need to be mean or rude.
+## Our Standards
 
-* Respect that people have differences of opinion and that every design
-  or implementation choice carries a trade-off and numerous costs. There
-  is seldom a right answer.
+Examples of behavior that contributes to creating a positive environment
+include:
 
-* Please keep unstructured critique to a minimum. If you have solid
-  ideas you want to experiment with, make a fork and see how it works.
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
 
-* We will exclude you from interaction if you insult, demean or harass
-  anyone. That is not welcome behaviour. We interpret the term
-  "harassment" as including the definition in the <a
-  href="http://citizencodeofconduct.org/">Citizen Code of Conduct</a>;
-  if you have any lack of clarity about what might be included in that
-  concept, please read their definition. In particular, we don't
-  tolerate behavior that excludes people in socially marginalized
-  groups.
+Examples of unacceptable behavior by participants include:
 
-* Private harassment is also unacceptable. No matter who you are, if you
-  feel you have been or are being harassed or made uncomfortable by a
-  community member, please contact one of the channel ops or any of the
-  Syncthing core team immediately. Whether you're a regular  contributor
-  or a newcomer, we care about making this community a safe place for
-  you and we've got your back.
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
 
-* Likewise any spamming, trolling, flaming, baiting or other
-  attention-stealing behaviour is not welcome.
+## Our Responsibilities
 
-## Moderation
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
 
-These are the policies for upholding our community's standards of
-conduct in our communication channels, most notably in Syncthing-related
-IRC channels and on the web forum.
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
 
-1. Remarks that violate the Syncthing standards of conduct, including
-   hateful, hurtful, oppressive, or exclusionary remarks, are not
-   allowed. (Cursing is allowed, but never targeting another user, and
-   never in a hateful manner.)
+## Scope
 
-2. Remarks that moderators find inappropriate, whether listed in the
-   code of conduct or not, are also not allowed.
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
 
-3. Moderators will first respond to such remarks with a warning.
+## Enforcement
 
-4. If the warning is unheeded, the user will be "kicked," i.e., kicked
-   out of the communication channel to cool off.
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at security@syncthing.net. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
 
-5. If the user comes back and continues to make trouble, they will be
-   banned, i.e., indefinitely excluded.
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
 
-6. Moderators may choose at their discretion to un-ban the user if it
-   was a first offense and they offer the offended party a genuine
-   apology.
+## Attribution
 
-7. If a moderator bans someone and you think it was unjustified, please
-   take it up with that moderator, or with a different moderator, **in
-   private**. Complaints about bans in-channel are not allowed.
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html
 
-8. Moderators are held to a higher standard than other community
-   members. If a moderator creates an inappropriate situation, they
-   should expect less leeway than others.
-
-In the Syncthing community we strive to go the extra step to look out
-for each other. Don't just aim to be technically unimpeachable, try to
-be your best self. In particular, avoid flirting with offensive or
-sensitive issues, particularly if they're off-topic; this all too
-often leads to unnecessary fights, hurt feelings, and damaged trust;
-worse, it can drive people away from the community entirely.
-
-And if someone takes issue with something you said or did, resist the
-urge to be defensive. Just stop doing what it was they complained about
-and apologize. Even if you feel you were misinterpreted or unfairly
-accused, chances are good there was something you could've communicated
-better — remember that it's your responsibility to make your fellow
-community members comfortable. Everyone wants to get along and we are
-all here first and foremost because we want to talk about cool
-technology. You will find that people will be eager to assume good
-intent and forgive as long as you earn their trust.

GOALS.md

+# The Syncthing Goals
+
+Syncthing is a **continuous file synchronization program**. It synchronizes
+files between two or more computers. We strive to fulfill the goals below.
+The goals are listed in order of importance, the most important one being
+the first.
+
+> "Syncing files" here is precise. It means we specifically exclude things
+> that are not files - calendar items, instant messages, and so on. If those
+> are in fact stored as files on disk, they can of course be synced as
+> files.
+
+Syncthing should be:
+
+### 1. Safe From Data Loss
+
+Protecting the user's data is paramount. We take every reasonable precaution
+to avoid corrupting the user's files.
+
+> This is the overriding goal, without which synchronizing files becomes
+> pointless. This means that we do not make unsafe trade offs for the sake
+> of performance or, in some cases, even usability.
+
+### 2. Secure Against Attackers
+
+Again, protecting the user's data is paramount. Regardless of our other
+goals, we must never allow the user's data to be susceptible to eavesdropping
+or modification by unauthorized parties.
+
+> This should be understood in context. It is not necessarily reasonable to
+> expect Syncthing to be resistant against well equipped state level
+> attackers. We will, however, do our best. Note also that this is different
+> from anonymity which is not, currently, a goal.
+
+### 3. Easy to Use
+
+Syncthing should be approachable, understandable, and inclusive.
+
+> Complex concepts and maths form the base of Syncthing's functionality.
+> This should nonetheless be abstracted or hidden to a degree where
+> Syncthing is usable by the general public.
+
+### 4. Automatic
+
+User interaction should be required only when absolutely necessary.
+
+> Specifically this means that changes to files are picked up without
+> prompting, conflicts are resolved without prompting and connections are
+> maintained without prompting. We only prompt the user when it is required
+> to fulfill one of the (overriding) Secure, Safe or Easy goals.
+
+### 5. Universally Available
+
+Syncthing should run on every common computer. We are mindful that the
+latest technology is not always available to every individual.
+
+> Computers include desktops, laptops, servers, virtual machines, small
+> general purpose computers such as Raspberry Pis and, *where possible*,
+> tablets and phones. NAS appliances, toasters, cars, firearms, thermostats,
+> and so on may include computing capabilities but it is not our goal for
+> Syncthing to run smoothly on these devices.
+
+### 6. For Individuals
+
+Syncthing is primarily about empowering the individual user with safe,
+secure, and easy to use file synchronization.
+
+> We acknowledge that it's also useful in an enterprise setting and include
+> functionality to support that. If this is in conflict with the
+> requirements of the individual, those will however take priority.
+
+### 7. Everything Else
+
+There are many things we care about that don't make it on to the list. It is
+fine to optimize for these values as well, as long as they are not in
+conflict with the stated goals above.
+
+> For example, performance is a thing we care about. We just don't care more
+> about it than safety, security, etc. Maintainability of the code base and
+> providing entertainment value for the maintainers are also things that
+> matter. It is understood that there are aspects of Syncthing that are
+> suboptimal or even in opposition with the goals above. However, we
+> continuously strive to align Syncthing more and more with these goals.

-ADVENTURE I. A SCANDAL IN BOHEMIA
-
-I.
-
-To Sherlock Holmes she is always THE woman. I have seldom heard
-him mention her under any other name. In his eyes she eclipses
-and predominates the whole of her sex. It was not that he felt
-any emotion akin to love for Irene Adler. All emotions, and that
-one particularly, were abhorrent to his cold, precise but
-admirably balanced mind. He was, I take it, the most perfect
-reasoning and observing machine that the world has seen, but as a
-lover he would have placed himself in a false position. He never
-spoke of the softer passions, save with a gibe and a sneer. They
-were admirable things for the observer--excellent for drawing the
-veil from men's motives and actions. But for the trained reasoner
-to admit such intrusions into his own delicate and finely
-adjusted temperament was to introduce a distracting factor which
-might throw a doubt upon all his mental results. Grit in a
-sensitive instrument, or a crack in one of his own high-power
-lenses, would not be more disturbing than a strong emotion in a
-nature such as his. And yet there was but one woman to him, and
-that woman was the late Irene Adler, of dubious and questionable
-memory.
-
-I had seen little of Holmes lately. My marriage had drifted us
-away from each other. My own complete happiness, and the
-home-centred interests which rise up around the man who first
-finds himself master of his own establishment, were sufficient to
-absorb all my attention, while Holmes, who loathed every form of
-society with his whole Bohemian soul, remained in our lodgings in
-Baker Street, buried among his old books, and alternating from
-week to week between cocaine and ambition, the drowsiness of the
-drug, and the fierce energy of his own keen nature. He was still,
-as ever, deeply attracted by the study of crime, and occupied his
-immense faculties and extraordinary powers of observation in
-following out those clues, and clearing up those mysteries which
-had been abandoned as hopeless by the official police. From time
-to time I heard some vague account of his doings: of his summons
-to Odessa in the case of the Trepoff murder, of his clearing up
-of the singular tragedy of the Atkinson brothers at Trincomalee,
-and finally of the mission which he had accomplished so
-delicately and successfully for the reigning family of Holland.
-Beyond these signs of his activity, however, which I merely
-shared with all the readers of the daily press, I knew little of
-my former friend and companion.

-Each encoded block begins with the varint-encoded length of the decoded data,

-Zero means a literal tag. All other values mean a copy tag.

-  - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
-    The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
-    of the offset. The next byte is bits 0-7 of the offset.
-  - For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
-    The length is 1 + m. The offset is the little-endian unsigned integer

-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the

-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-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.

-    import "github.com/juju/ratelimit"
-
-The ratelimit package provides an efficient token bucket implementation. See
-http://en.wikipedia.org/wiki/Token_bucket.
-
-## Usage
-
-#### func  Reader
-
-```go
-func Reader(r io.Reader, bucket *Bucket) io.Reader
-```
-Reader returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### func  Writer
-
-```go
-func Writer(w io.Writer, bucket *Bucket) io.Writer
-```
-Writer returns a writer that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### type Bucket
-
-```go
-type Bucket struct {
-}
-```
-
-Bucket represents a token bucket that fills at a predetermined rate. Methods on
-Bucket may be called concurrently.
-
-#### func  NewBucket
-
-```go
-func NewBucket(fillInterval time.Duration, capacity int64) *Bucket
-```
-NewBucket returns a new token bucket that fills at the rate of one token every
-fillInterval, up to the given maximum capacity. Both arguments must be positive.
-The bucket is initially full.
-
-#### func  NewBucketWithQuantum
-
-```go
-func NewBucketWithQuantum(fillInterval time.Duration, capacity, quantum int64) *Bucket
-```
-NewBucketWithQuantum is similar to NewBucket, but allows the specification of
-the quantum size - quantum tokens are added every fillInterval.
-
-#### func  NewBucketWithRate
-
-```go
-func NewBucketWithRate(rate float64, capacity int64) *Bucket
-```
-NewBucketWithRate returns a token bucket that fills the bucket at the rate of
-rate tokens per second up to the given maximum capacity. Because of limited
-clock resolution, at high rates, the actual rate may be up to 1% different from
-the specified rate.
-
-#### func (*Bucket) Rate
-
-```go
-func (tb *Bucket) Rate() float64
-```
-Rate returns the fill rate of the bucket, in tokens per second.
-
-#### func (*Bucket) Take
-
-```go
-func (tb *Bucket) Take(count int64) time.Duration
-```
-Take takes count tokens from the bucket without blocking. It returns the time
-that the caller should wait until the tokens are actually available.
-
-Note that if the request is irrevocable - there is no way to return tokens to
-the bucket once this method commits us to taking them.
-
-#### func (*Bucket) TakeAvailable
-
-```go
-func (tb *Bucket) TakeAvailable(count int64) int64
-```
-TakeAvailable takes up to count immediately available tokens from the bucket. It
-returns the number of tokens removed, or zero if there are no available tokens.
-It does not block.
-
-#### func (*Bucket) TakeMaxDuration
-
-```go
-func (tb *Bucket) TakeMaxDuration(count int64, maxWait time.Duration) (time.Duration, bool)
-```
-TakeMaxDuration is like Take, except that it will only take tokens from the
-bucket if the wait time for the tokens is no greater than maxWait.
-
-If it would take longer than maxWait for the tokens to become available, it does
-nothing and reports false, otherwise it returns the time that the caller should
-wait until the tokens are actually available, and reports true.
-
-#### func (*Bucket) Wait
-
-```go
-func (tb *Bucket) Wait(count int64)
-```
-Wait takes count tokens from the bucket, waiting until they are available.
-
-#### func (*Bucket) WaitMaxDuration
-
-```go
-func (tb *Bucket) WaitMaxDuration(count int64, maxWait time.Duration) bool
-```
-WaitMaxDuration is like Wait except that it will only take tokens from the
-bucket if it needs to wait for no greater than maxWait. It reports whether any
-tokens have been removed from the bucket If no tokens have been removed, it
-returns immediately.

-## Find the current Executable and ExecutableFolder.
-
-There is sometimes utility in finding the current executable file
-that is running. This can be used for upgrading the current executable
-or finding resources located relative to the executable file. Both
-working directory and the os.Args[0] value are arbitrary and cannot
-be relied on; os.Args[0] can be "faked".
-
-Multi-platform and supports:
- * Linux
- * OS X
- * Windows
- * Plan 9
- * BSDs.

-go-metrics
-==========
-
-![travis build status](https://travis-ci.org/rcrowley/go-metrics.svg?branch=master)
-
-Go port of Coda Hale's Metrics library: <https://github.com/dropwizard/metrics>.
-
-Documentation: <http://godoc.org/github.com/rcrowley/go-metrics>.
-
-Usage
------
-
-Create and update metrics:
-
-```go
-c := metrics.NewCounter()
-metrics.Register("foo", c)
-c.Inc(47)
-
-g := metrics.NewGauge()
-metrics.Register("bar", g)
-g.Update(47)
-
-s := metrics.NewExpDecaySample(1028, 0.015) // or metrics.NewUniformSample(1028)
-h := metrics.NewHistogram(s)
-metrics.Register("baz", h)
-h.Update(47)
-
-m := metrics.NewMeter()
-metrics.Register("quux", m)
-m.Mark(47)
-
-t := metrics.NewTimer()
-metrics.Register("bang", t)
-t.Time(func() {})
-t.Update(47)
-```
-
-Periodically log every metric in human-readable form to standard error:
-
-```go
-go metrics.Log(metrics.DefaultRegistry, 60e9, log.New(os.Stderr, "metrics: ", log.Lmicroseconds))
-```
-
-Periodically log every metric in slightly-more-parseable form to syslog:
-
-```go
-w, _ := syslog.Dial("unixgram", "/dev/log", syslog.LOG_INFO, "metrics")
-go metrics.Syslog(metrics.DefaultRegistry, 60e9, w)
-```
-
-Periodically emit every metric to Graphite using the [Graphite client](https://github.com/cyberdelia/go-metrics-graphite):
-
-```go
-
-import "github.com/cyberdelia/go-metrics-graphite"
-
-addr, _ := net.ResolveTCPAddr("tcp", "127.0.0.1:2003")
-go graphite.Graphite(metrics.DefaultRegistry, 10e9, "metrics", addr)
-```
-
-Periodically emit every metric into InfluxDB:
-
-**NOTE:** this has been pulled out of the library due to constant fluctuations
-in the InfluxDB API. In fact, all client libraries are on their way out. see
-issues [#121](https://github.com/rcrowley/go-metrics/issues/121) and
-[#124](https://github.com/rcrowley/go-metrics/issues/124) for progress and details.
-
-```go
-import "github.com/rcrowley/go-metrics/influxdb"
-
-go influxdb.Influxdb(metrics.DefaultRegistry, 10e9, &influxdb.Config{
-    Host:     "127.0.0.1:8086",
-    Database: "metrics",
-    Username: "test",
-    Password: "test",
-})
-```
-
-Periodically upload every metric to Librato using the [Librato client](https://github.com/mihasya/go-metrics-librato):
-
-**Note**: the client included with this repository under the `librato` package
-has been deprecated and moved to the repository linked above.
-
-```go
-import "github.com/mihasya/go-metrics-librato"
-
-go librato.Librato(metrics.DefaultRegistry,
-    10e9,                  // interval
-    "example@example.com", // account owner email address
-    "token",               // Librato API token
-    "hostname",            // source
-    []float64{0.95},       // percentiles to send
-    time.Millisecond,      // time unit
-)
-```
-
-Periodically emit every metric to StatHat:
-
-```go
-import "github.com/rcrowley/go-metrics/stathat"
-
-go stathat.Stathat(metrics.DefaultRegistry, 10e9, "example@example.com")
-```
-
-Installation
-------------
-
-```sh
-go get github.com/rcrowley/go-metrics
-```
-
-StatHat support additionally requires their Go client:
-
-```sh
-go get github.com/stathat/go
-```
-
-Publishing Metrics
-------------------
-
-Clients are available for the following destinations:
-
-* Librato - [https://github.com/mihasya/go-metrics-librato](https://github.com/mihasya/go-metrics-librato)
-* Graphite - [https://github.com/cyberdelia/go-metrics-graphite](https://github.com/cyberdelia/go-metrics-graphite)
-* InfluxDB - [https://github.com/vrischmann/go-metrics-influxdb](https://github.com/vrischmann/go-metrics-influxdb)
