-## 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.
-
-* On IRC, please avoid using overtly sexual nicknames or other nicknames
-  that might detract from a friendly, safe and welcoming environment for
-  all.
-
-* Please be kind and courteous. There's no need to be mean or rude.
-
-* 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.
-
-* 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.
-
-* 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.
-
-* 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.
-
-* Likewise any spamming, trolling, flaming, baiting or other
-  attention-stealing behaviour is not welcome.
-
-## Moderation
-
-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.
-
-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.)
-
-2. Remarks that moderators find inappropriate, whether listed in the
-   code of conduct or not, are also not allowed.
-
-3. Moderators will first respond to such remarks with a warning.
-
-4. If the warning is unheeded, the user will be "kicked," i.e., kicked
-   out of the communication channel to cool off.
-
-5. If the user comes back and continues to make trouble, they will be
-   banned, i.e., indefinitely excluded.
-
-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.
-
-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.
-
-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.

-## Reporting Bugs
-
-Please file bugs in the [Github Issue
-Tracker](https://github.com/syncthing/syncthing/issues). Include at
-least the following:
-
- - What happened
-
- - What did you expect to happen instead of what *did* happen, if it's
-   not crazy obvious
-
- - What operating system, operating system version and version of
-   Syncthing you are running
-
- - The same for other connected devices, where relevant
-
- - Screenshot if the issue concerns something visible in the GUI
-
- - Console log entries, where possible and relevant
-
-If you're not sure whether something is relevant, erring on the side of
-too much information will never get you yelled at. :)
-
-## Contributing Translations
-
-All translations are done via
-[Transifex](https://www.transifex.com/projects/p/syncthing/). If you
-wish to contribute to a translation, just head over there and sign up.
-Before every release, the language resources are updated from the
-latest info on Transifex.
-
-## Contributing Code
-
-Every contribution is welcome. If you want to contribute but are unsure
-where to start, any open issues are fair game! Be prepared for a
-[certain amount of review](https://github.com/syncthing/syncthing/wiki/FAQ#why-are-you-being-so-hard-on-my-pull-request);
-it's all in the name of quality. :) Following the points below will make this
-a smoother process.
-
-Individuals making significant and valuable contributions are given
-commit-access to the project. If you make a significant contribution and
-are not considered for commit-access, please contact any of the
-Syncthing core team members.
-
-All nontrivial contributions should go through the pull request
-mechanism for internal review. Determining what is "nontrivial" is left
-at the discretion of the contributor.
-
-### Authorship
-
-All code authors are listed in the AUTHORS file. Commits must be made
-with the same name and email as listed in the AUTHORS file. To
-accomplish this, ensure that your git configuration is set correctly
-prior to making your first commit;
-
-    $ git config --global user.name "Jane Doe"
-    $ git config --global user.email janedoe@example.com
-
-You must be reachable on the given email address. If you do not wish to
-use your real name for whatever reason, using a nickname or pseudonym is
-perfectly acceptable.
-
-### Core Team
-
-The Syncthing core team currently consists of the following members;
-
- - Jakob Borg (@calmh)
- - Audrius Butkevicius (@AudriusButkevicius)
-
-## Coding Style
-
- Follow the conventions laid out in [Effective Go](https://golang.org/doc/effective_go.html)
-  as much as makes sense.
-
- All text files use Unix line endings.
-
- Each commit should be `go fmt` clean.
-
- The commit message subject should be a single short sentence
-  describing the change, starting with a capital letter.
-
- Commits that resolve an existing issue must include the issue number
-  as `(fixes #123)` at the end of the commit message subject.
-
- Imports are grouped per `goimports` standard; that is, standard
-  library first, then third party libraries after a blank line.
-
- A contribution solving a single issue or introducing a single new
-  feature should probably be a single commit based on the current
-  `master` branch. You may be asked to "rebase" or "squash" your pull
-  request to make sure this is the case, especially if there have been
-  amendments during review.
-
-## Licensing
-
-All contributions are made under the same MPLv2 license as the rest of
-the project, except documentation, user interface text and translation
-strings which are licensed under the Creative Commons Attribution 4.0
-International License. You retain the copyright to code you have
-written.
-
-When accepting your first contribution, the maintainer of the project
-will ensure that you are added to the AUTHORS file. You are welcome to
-add yourself as a separate commit in your first pull request.
-
-## Building
-
-[See the documentation](https://github.com/syncthing/syncthing/wiki/Building)
-on how to get started with a build environment.
-
-## Branches
-
- - `master` is the main branch containing good code that will end up in
-   the next release. You should base your work on it. It won't ever be
-   rebased or force-pushed to.
-
- - `vx.y` branches exist to make patch releases on otherwise obsolete
-   minor releases. Should only contain fixes cherry picked from master.
-   Don't base any work on them.
-
- - Other branches are probably topic branches and may be subject to
-   rebasing. Don't base any work on them unless you specifically know
-   otherwise.
-
-## Tags
-
-All releases are tagged semver style as `vx.y.z`. Release tags are
-signed by GPG key BCE524C7.
-
-## Tests
-
-Yes please!

-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.

-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-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

-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.

-
-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 reader 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.

-    $ git config --global user.name "Jane Doe"
-    $ git config --global user.email janedoe@example.com
-
-You must be reachable on the given email address. If you do not wish to
-use your real name for whatever reason, using a nickname or pseudonym is
-perfectly acceptable.
-
-## Coding Style
-
- Follow the conventions laid out in [Effective Go](https://golang.org/doc/effective_go.html)
-  as much as makes sense.
-
- All text files use Unix line endings.
-
- Each commit should be `go fmt` clean.
-
- The commit message subject should be a single short sentence
-  describing the change, starting with a capital letter.
-
- Commits that resolve an existing issue must include the issue number
-  as `(fixes #123)` at the end of the commit message subject.
-
- Imports are grouped per `goimports` standard; that is, standard
-  library first, then third party libraries after a blank line.
-
- A contribution solving a single issue or introducing a single new
-  feature should probably be a single commit based on the current
-  `master` branch. You may be asked to "rebase" or "squash" your pull
-  request to make sure this is the case, especially if there have been
-  amendments during review.
