+# unzipper
+
+This is an active fork and drop-in replacement of the [node-unzip](https://github.com/EvanOxfeld/node-unzip) and addresses the following issues:
+* finish/close events are not always triggered, particular when the input stream is slower than the receivers
+* Any files are buffered into memory before passing on to entry
+
+The structure of this fork is similar to the original, but uses Promises and inherit guarantees provided by node streams to ensure low memory footprint and emits finish/close events at the end of processing.   The new `Parser` will push any parsed `entries` downstream if you pipe from it, while still supporting the legacy `entry` event as well.
+
+Breaking changes: The new `Parser` will not automatically drain entries if there are no listeners or pipes in place.
+
+Unzipper provides simple APIs similar to [node-tar](https://github.com/isaacs/node-tar) for parsing and extracting zip files.
+There are no added compiled dependencies - inflation is handled by node.js's built in zlib support.
+
+Please note:  Methods that use the Central Directory instead of parsing entire file can be found under [`Open`](#open)
+
+Chrome extension files (.crx) are zipfiles with an [extra header](http://www.adambarth.com/experimental/crx/docs/crx.html) at the start of the file.  Unzipper will parse .crx file with the streaming methods (`Parse` and `ParseOne`).  The `Open` methods will check for `crx` headers and parse crx files, but only if you provide `crx: true` in options.  
+
+## Installation
+
+```bash
+$ npm install unzipper
+```
+
+## Quick Examples
+
+### Extract to a directory
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Extract({ path: 'output/path' }));
+```
+
+Extract emits the 'close' event once the zip's contents have been fully extracted to disk. `Extract` uses [fstream.Writer](https://www.npmjs.com/package/fstream) and therefore needs need an absolute path to the destination directory.  This directory will be automatically created if it doesn't already exits.
+
+### Parse zip file contents
+
+Process each zip file entry or pipe entries to another stream.
+
+__Important__: If you do not intend to consume an entry stream's raw data, call autodrain() to dispose of the entry's
+contents. Otherwise the stream will halt.   `.autodrain()` returns an empty stream that provides `error` and `finish` events.
+Additionally you can call `.autodrain().promise()` to get the promisified version of success or failure of the autodrain.
+
+```js
+// If you want to handle autodrain errors you can either:
+entry.autodrain().catch(e => handleError);
+// or
+entry.autodrain().on('error' => handleError);
+```
+
+Here is a quick example:
+
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', function (entry) {
+    const fileName = entry.path;
+    const type = entry.type; // 'Directory' or 'File'
+    const size = entry.vars.uncompressedSize; // There is also compressedSize;
+    if (fileName === "this IS the file I'm looking for") {
+      entry.pipe(fs.createWriteStream('output/path'));
+    } else {
+      entry.autodrain();
+    }
+  });
+```
+### Parse zip by piping entries downstream
+
+If you `pipe` from unzipper the downstream components will receive each `entry` for further processing.   This allows for clean pipelines transforming zipfiles into unzipped data.
+
+Example using `stream.Transform`:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(stream.Transform({
+    objectMode: true,
+    transform: function(entry,e,cb) {
+      const fileName = entry.path;
+      const type = entry.type; // 'Directory' or 'File'
+      const size = entry.vars.uncompressedSize; // There is also compressedSize;
+      if (fileName === "this IS the file I'm looking for") {
+        entry.pipe(fs.createWriteStream('output/path'))
+          .on('finish',cb);
+      } else {
+        entry.autodrain();
+        cb();
+      }
+    }
+  }
+  }));
+```
+
+Example using [etl](https://www.npmjs.com/package/etl):
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(etl.map(entry => {
+    if (entry.path == "this IS the file I'm looking for")
+      return entry
+        .pipe(etl.toFile('output/path'))
+        .promise();
+    else
+      entry.autodrain();
+  }))
+
+```
+
+### Parse a single file and pipe contents
+
+`unzipper.parseOne([regex])` is a convenience method that unzips only one file from the archive and pipes the contents down (not the entry itself).  If no serch criteria is specified, the first file in the archive will be unzipped.  Otherwise, each filename will be compared to the criteria and the first one to match will be unzipped and piped down.  If no file matches then the the stream will end without any content.
+
+Example:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.ParseOne())
+  .pipe(fs.createReadStream('firstFile.txt'));
+```
+
+### Buffering the content of an entry into memory
+
+While the recommended strategy of consuming the unzipped contents is using streams, it is sometimes convenient to be able to get the full buffered contents of each file .  Each `entry` provides a `.buffer` function that consumes the entry by buffering the contents into memory and returning a promise to the complete buffer.
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .pipe(etl.map(async entry => {
+    if (entry.path == "this IS the file I'm looking for") {
+      const content = await entry.buffer();
+      await fs.writeFile('output/path',content);
+    }
+    else {
+      entry.autodrain();
+    }
+  }))
+```
+
+### Parse.promise() syntax sugar
+
+The parser emits `finish` and `error` events like any other stream.  The parser additionally provides a promise wrapper around those two events to allow easy folding into existing Promise-based structures.
+
+Example:
+
+```js
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', entry => entry.autodrain())
+  .promise()
+  .then( () => console.log('done'), e => console.log('error',e));
+```
+
+### Parse zip created by DOS ZIP or Windows ZIP Folders
+
+Archives created by legacy tools usually have filenames encoded with IBM PC (Windows OEM) character set.
+You can decode filenames with preferred character set:
+
+```js
+const il = require('iconv-lite');
+fs.createReadStream('path/to/archive.zip')
+  .pipe(unzipper.Parse())
+  .on('entry', function (entry) {
+    // if some legacy zip tool follow ZIP spec then this flag will be set
+    const isUnicode = entry.props.flags.isUnicode;
+    // decode "non-unicode" filename from OEM Cyrillic character set
+    const fileName = isUnicode ? entry.path : il.decode(entry.props.pathBuffer, 'cp866');
+    const type = entry.type; // 'Directory' or 'File'
+    const size = entry.vars.uncompressedSize; // There is also compressedSize;
+    if (fileName === "Текстовый файл.txt") {
+      entry.pipe(fs.createWriteStream(fileName));
+    } else {
+      entry.autodrain();
+    }
+  });
+```
+
+## Open
+Previous methods rely on the entire zipfile being received through a pipe.  The Open methods load take a different approach: load the central directory first (at the end of the zipfile) and provide the ability to pick and choose which zipfiles to extract, even extracting them in parallel.   The open methods return a promise on the contents of the directory, with individual `files` listed in an array.   Each file element has the following methods:
+* `stream([password])` - returns a stream of the unzipped content which can be piped to any destination
+* `buffer([password])` - returns a promise on the buffered content of the file)
+If the file is encrypted you will have to supply a password to decrypt, otherwise you can leave blank.
+Unlike `adm-zip` the Open methods will never read the entire zipfile into buffer.
+
+The last argument is optional `options` object where you can specify `tailSize` (default 80 bytes), i.e. how many bytes should we read at the end of the zipfile to locate the endOfCentralDirectory.  This location can be variable depending on zip64 extensible data sector size.   Additionally you can supply option `crx: true` which will check for a crx header and parse the file accordingly by shifting all file offsets by the length of the crx header.
+
+### Open.file([path], [options])
+Returns a Promise to the central directory information with methods to extract individual files.   `start` and `end` options are used to avoid reading the whole file.
+
+Example:
+```js
+async function main() {
+  const directory = await unzipper.Open.file('path/to/archive.zip');
+  console.log('directory', d);
+  return new Promise( (resolve, reject) => {
+    directory.files[0]
+      .stream()
+      .pipe(fs.createWriteStream('firstFile'))
+      .on('error',reject)
+      .on('finish',resolve)
+  });
+}
+
+main();
+```
+
+### Open.url([requestLibrary], [url | params], [options])
+This function will return a Promise to the central directory information from a URL point to a zipfile.  Range-headers are used to avoid reading the whole file. Unzipper does not ship with a request library so you will have to provide it as the first option.
+
+Live Example: (extracts a tiny xml file from the middle of a 500MB zipfile)
+
+```js
+const request = require('request');
+const unzipper = require('./unzip');
+
+async function main() {
+  const directory = await unzipper.Open.url(request,'http://www2.census.gov/geo/tiger/TIGER2015/ZCTA5/tl_2015_us_zcta510.zip');
+  const file = directory.files.find(d => d.path === 'tl_2015_us_zcta510.shp.iso.xml');
+  const content = await file.buffer();
+  console.log(content.toString());
+}
+
+main();
+```
+
+
+This function takes a second parameter which can either be a string containing the `url` to request, or an `options` object to invoke the supplied `request` library with. This can be used when other request options are required, such as custom headers or authentication to a third party service.
+
+```js
+const request = require('google-oauth-jwt').requestWithJWT();
+
+const googleStorageOptions = {
+  url: `https://www.googleapis.com/storage/v1/b/m-bucket-name/o/my-object-name`,
+  qs: { alt: 'media' },
+  jwt: {
+      email: google.storage.credentials.client_email,
+      key: google.storage.credentials.private_key,
+      scopes: ['https://www.googleapis.com/auth/devstorage.read_only']
+  }
+});
+
+async function getFile(req, res, next) {
+  const directory = await unzipper.Open.url(request, googleStorageOptions);
+  const file = zip.files.find((file) => file.path === 'my-filename');
+  return file.stream().pipe(res);
+});
+```
+
+### Open.s3([aws-sdk], [params], [options])
+This function will return a Promise to the central directory information from a zipfile on S3.  Range-headers are used to avoid reading the whole file.    Unzipper does not ship with with the aws-sdk so you have to provide an instantiated client as first arguments.    The params object requires `Bucket` and `Key` to fetch the correct file.
+
+Example:
+
+```js
+const unzipper = require('./unzip');
+const AWS = require('aws-sdk');
+const s3Client = AWS.S3(config);
+
+async function main() {
+  const directory = await unzipper.Open.s3(s3Client,{Bucket: 'unzipper', Key: 'archive.zip'});
+  return new Promise( (resolve, reject) => {
+    directory.files[0]
+      .stream()
+      .pipe(fs.createWriteStream('firstFile'))
+      .on('error',reject)
+      .on('finish',resolve)
+  });
+}
+
+main();
+```
+
+### Open.buffer(buffer, [options])
+If you already have the zip file in-memory as a buffer, you can open the contents directly.
+
+Example:
+
+```js
+// never use readFileSync - only used here to simplify the example
+const buffer = fs.readFileSync('path/to/arhive.zip');
+
+async function main() {
+  const directory = await unzipper.Open.buffer(buffer);
+  console.log('directory',directory);
+  // ...
+}
+
+main();
+```
+
+### Open.[method].extract()
+
+The directory object returned from `Open.[method]` provides an `extract` method which extracts all the files to a specified `path`, with an optional `concurrency` (default: 1).
+
+Example (with concurrency of 5):
+
+```js
+unzip.Open.file('path/to/archive.zip')
+  .then(d => d.extract({path: '/extraction/path', concurrency: 5}));
+```

+Like FS streams, but with stat on them, and supporting directories and
+symbolic links, as well as normal files.  Also, you can use this to set
+the stats on a file, even if you don't change its contents, or to create
+a symlink, etc.
+
+So, for example, you can "write" a directory, and it'll call `mkdir`.  You
+can specify a uid and gid, and it'll call `chown`.  You can specify a
+`mtime` and `atime`, and it'll call `utimes`.  You can call it a symlink
+and provide a `linkpath` and it'll call `symlink`.
+
+Note that it won't automatically resolve symbolic links.  So, if you
+call `fstream.Reader('/some/symlink')` then you'll get an object
+that stats and then ends immediately (since it has no data).  To follow
+symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow:
+true })`.
+
+There are various checks to make sure that the bytes emitted are the
+same as the intended size, if the size is set.
+
+## Examples
+
+```javascript
+fstream
+  .Writer({ path: "path/to/file"
+          , mode: 0755
+          , size: 6
+          })
+  .write("hello\n")
+  .end()
+```
+
+This will create the directories if they're missing, and then write
+`hello\n` into the file, chmod it to 0755, and assert that 6 bytes have
+been written when it's done.
+
+```javascript
+fstream
+  .Writer({ path: "path/to/file"
+          , mode: 0755
+          , size: 6
+          , flags: "a"
+          })
+  .write("hello\n")
+  .end()
+```
+
+You can pass flags in, if you want to append to a file.
+
+```javascript
+fstream
+  .Writer({ path: "path/to/symlink"
+          , linkpath: "./file"
+          , SymbolicLink: true
+          , mode: "0755" // octal strings supported
+          })
+  .end()
+```
+
+If isSymbolicLink is a function, it'll be called, and if it returns
+true, then it'll treat it as a symlink.  If it's not a function, then
+any truish value will make a symlink, or you can set `type:
+'SymbolicLink'`, which does the same thing.
+
+Note that the linkpath is relative to the symbolic link location, not
+the parent dir or cwd.
+
+```javascript
+fstream
+  .Reader("path/to/dir")
+  .pipe(fstream.Writer("path/to/other/dir"))
+```
+
+This will do like `cp -Rp path/to/dir path/to/other/dir`.  If the other
+dir exists and isn't a directory, then it'll emit an error.  It'll also
+set the uid, gid, mode, etc. to be identical.  In this way, it's more
+like `rsync -a` than simply a copy.

node_modules/unzipper/node_modules/readable-stream/GOVERNANCE.md

@@ -0,0 +1,136 @@
+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+
+***Node-core v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.
