+
+Name
+----
+
+`klaw` is `walk` backwards :p
+
+
+Usage
+-----
+
+### klaw(directory, [options])
+
+Returns a [Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) that iterates
+through every file and directory starting with `dir` as the root. Every `read()` or `data` event
+returns an object with two properties: `path` and `stats`. `path` is the full path of the file and
+`stats` is an instance of [fs.Stats](https://nodejs.org/api/fs.html#fs_class_fs_stats).
+
+- `directory`: The directory to recursively walk. Type `string`.
+- `options`: [Readable stream options](https://nodejs.org/api/stream.html#stream_new_stream_readable_options) and
+the following:
+  - `queueMethod` (`string`, default: `'shift'`): Either `'shift'` or `'pop'`. On `readdir()` array, call either `shift()` or `pop()`.
+  - `pathSorter` (`function`, default: `undefined`): Sorting [function for Arrays](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort).
+  - `fs` (`object`, default: `require('fs')`): Use this to hook into the `fs` methods or to use [`mock-fs`](https://github.com/tschaub/mock-fs)
+  - `filter` (`function`, default: `undefined`): Filtering [function for Arrays](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter)
+
+**Streams 1 (push) example:**
+
+```js
+var klaw = require('klaw')
+
+var items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('data', function (item) {
+    items.push(item.path)
+  })
+  .on('end', function () {
+    console.dir(items) // => [ ... array of files]
+  })
+```
+
+**Streams 2 & 3 (pull) example:**
+
+```js
+var klaw = require('klaw')
+
+var items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('readable', function () {
+    var item
+    while ((item = this.read())) {
+      items.push(item.path)
+    }
+  })
+  .on('end', function () {
+    console.dir(items) // => [ ... array of files]
+  })
+```
+
+If you're not sure of the differences on Node.js streams 1, 2, 3 then I'd
+recommend this resource as a good starting point: https://strongloop.com/strongblog/whats-new-io-js-beta-streams3/.
+
+
+### Error Handling
+
+Listen for the `error` event.
+
+Example:
+
+```js
+var klaw = require('klaw')
+klaw('/some/dir')
+  .on('readable', function () {
+    var item
+    while ((item = this.read())) {
+      // do something with the file
+    }
+  })
+  .on('error', function (err, item) {
+    console.log(err.message)
+    console.log(item.path) // the file the error occurred on
+  })
+  .on('end', function () {
+    console.dir(items) // => [ ... array of files]
+  })
+
+```
+
+
+### Aggregation / Filtering / Executing Actions (Through Streams)
+
+On many occasions you may want to filter files based upon size, extension, etc.
+Or you may want to aggregate stats on certain file types. Or maybe you want to
+perform an action on certain file types.
+
+You should use the module [`through2`](https://www.npmjs.com/package/through2) to easily
+accomplish this.
+
+Install `through2`:
+
+    npm i --save through2
+
+
+**Example (skipping directories):**
+
+```js
+var klaw = require('klaw')
+var through2 = require('through2')
+
+var excludeDirFilter = through2.obj(function (item, enc, next) {
+  if (!item.stats.isDirectory()) this.push(item)
+  next()
+})
+
+var items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .pipe(excludeDirFilter)
+  .on('data', function (item) {
+    items.push(item.path)
+  })
+  .on('end', function () {
+    console.dir(items) // => [ ... array of files without directories]
+  })
+
+```
+**Example (ignore hidden directories):**
+```js
+var klaw = require('klaw')
+var path = require('path')
+
+var filterFunc = function(item){
+  var basename = path.basename(item)
+  return basename === '.' || basename[0] !== '.'
+}
+
+klaw('/some/dir', { filter : filterFunc  })
+  .on('data', function(item){
+    // only items of none hidden folders will reach here
+  })
+    
+```
+
+**Example (totaling size of PNG files):**
+
+```js
+var klaw = require('klaw')
+var path = require('path')
+var through2 = require('through2')
+
+var totalPngsInBytes = 0
+var aggregatePngSize = through2.obj(function (item, enc, next) {
+  if (path.extname(item.path) === '.png') {
+    totalPngsInBytes += item.stats.size
+  }
+  this.push(item)
+  next()
+})
+
+klaw('/some/dir')
+  .pipe(aggregatePngSize)
+  .on('data', function (item) {
+    items.push(item.path)
+  })
+  .on('end', function () {
+    console.dir(totalPngsInBytes) // => total of all pngs (bytes)
+  })
+```
+
+
+**Example (deleting all .tmp files):**
+
+```js
+var fs = require('fs')
+var klaw = require('klaw')
+var through2 = require('through2')
+
+var deleteAction = through2.obj(function (item, enc, next) {
+  this.push(item)
+
+  if (path.extname(item.path) === '.tmp') {
+    item.deleted = true
+    fs.unklink(item.path, next)
+  } else {
+    item.deleted = false
+    next()
+  }  
+})
+
+var deletedFiles = []
+klaw('/some/dir')
+  .pipe(deleteAction)
+  .on('data', function (item) {
+    if (!item.deleted) return
+    deletedFiles.push(item.path)
+  })
+  .on('end', function () {
+    console.dir(deletedFiles) // => all deleted files
+  })
+```
+
+You can even chain a bunch of these filters and aggregators together. By using
+multiple pipes.
+
+**Example (using multiple filters / aggregators):**
+
+```js
+klaw('/some/dir')
+  .pipe(filterCertainFiles)
+  .pipe(deleteSomeOtherFiles)
+  .on('end', function () {
+    console.log('all done!')
+  })
+```
+
+**Example passing (piping) through errors:**
+
+Node.js does not `pipe()` errors. This means that the error on one stream, like
+`klaw` will not pipe through to the next. If you want to do this, do the following:
+
+```js
+var klaw = require('klaw')
+var through2 = require('through2')
+
+var excludeDirFilter = through2.obj(function (item, enc, next) {
+  if (!item.stats.isDirectory()) this.push(item)
+  next()
+})
+
+var items = [] // files, directories, symlinks, etc
+klaw('/some/dir')
+  .on('error', function (err) { excludeDirFilter.emit('error', err) }) // forward the error on
+  .pipe(excludeDirFilter)
+  .on('data', function (item) {
+    items.push(item.path)
+  })
+  .on('end', function () {
+    console.dir(items) // => [ ... array of files without directories]
+  })
+```
+
+
+### Searching Strategy
+
+Pass in options for `queueMethod` and `pathSorter` to affect how the file system
+is recursively iterated. See the code for more details, it's less than 50 lines :)

+# graceful-fs
+
+graceful-fs functions as a drop-in replacement for the fs module,
+making various improvements.
+
+The improvements are meant to normalize behavior across different
+platforms and environments, and to make filesystem access more
+resilient to errors.
+
+## Improvements over [fs module](https://nodejs.org/api/fs.html)
+
+* Queues up `open` and `readdir` calls, and retries them once
+  something closes if there is an EMFILE error from too many file
+  descriptors.
+* fixes `lchmod` for Node versions prior to 0.6.2.
+* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
+* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
+  `lchown` if the user isn't root.
+* makes `lchmod` and `lchown` become noops, if not available.
+* retries reading a file if `read` results in EAGAIN error.
+
+On Windows, it retries renaming a file for up to one second if `EACCESS`
+or `EPERM` error occurs, likely because antivirus software has locked
+the directory.
+
+## USAGE
+
+```javascript
+// use just like fs
+var fs = require('graceful-fs')
+
+// now go and do stuff with it...
+fs.readFile('some-file-or-whatever', (err, data) => {
+  // Do stuff here.
+})
+```
+
+## Sync methods
+
+This module cannot intercept or handle `EMFILE` or `ENFILE` errors from sync
+methods.  If you use sync methods which open file descriptors then you are
+responsible for dealing with any errors.
+
+This is a known limitation, not a bug.
+
+## Global Patching
+
+If you want to patch the global fs module (or any other fs-like
+module) you can do this:
+
+```javascript
+// Make sure to read the caveat below.
+var realFs = require('fs')
+var gracefulFs = require('graceful-fs')
+gracefulFs.gracefulify(realFs)
+```
+
+This should only ever be done at the top-level application layer, in
+order to delay on EMFILE errors from any fs-using dependencies.  You
+should **not** do this in a library, because it can cause unexpected
+delays in other parts of the program.
+
+## Changes
+
+This module is fairly stable at this point, and used by a lot of
+things.  That being said, because it implements a subtle behavior
+change in a core part of the node API, even modest changes can be
+extremely breaking, and the versioning is thus biased towards
+bumping the major when in doubt.
+
+The main change between major versions has been switching between
+providing a fully-patched `fs` module vs monkey-patching the node core
+builtin, and the approach by which a non-monkey-patched `fs` was
+created.
+
+The goal is to trade `EMFILE` errors for slower fs operations.  So, if
+you try to open a zillion files, rather than crashing, `open`
+operations will be queued up and wait for something else to `close`.
+
+There are advantages to each approach.  Monkey-patching the fs means
+that no `EMFILE` errors can possibly occur anywhere in your
+application, because everything is using the same core `fs` module,
+which is patched.  However, it can also obviously cause undesirable
+side-effects, especially if the module is loaded multiple times.
+
+Implementing a separate-but-identical patched `fs` module is more
+surgical (and doesn't run the risk of patching multiple times), but
+also imposes the challenge of keeping in sync with the core module.
+
+The current approach loads the `fs` module, and then creates a
+lookalike object that has all the same methods, except a few that are
+patched.  It is safe to use in all versions of Node from 0.8 through
+7.0.
+
+### v4
+
+* Do not monkey-patch the fs module.  This module may now be used as a
+  drop-in dep, and users can opt into monkey-patching the fs builtin
+  if their app requires it.
+
+### v3
+
+* Monkey-patch fs, because the eval approach no longer works on recent
+  node.
+* fixed possible type-error throw if rename fails on windows
+* verify that we *never* get EMFILE errors
+* Ignore ENOSYS from chmod/chown
+* clarify that graceful-fs must be used as a drop-in
+
+### v2.1.0
+
+* Use eval rather than monkey-patching fs.
+* readdir: Always sort the results
+* win32: requeue a file if error has an OK status
+
+### v2.0
+
+* A return to monkey patching
+* wrap process.cwd
+
+### v1.1
+
+* wrap readFile
+* Wrap fs.writeFile.
+* readdir protection
+* Don't clobber the fs builtin
+* Handle fs.read EAGAIN errors by trying again
+* Expose the curOpen counter
+* No-op lchown/lchmod if not implemented
+* fs.rename patch only for win32
+* Patch fs.rename to handle AV software on Windows
+* Close #4 Chown should not fail on einval or eperm if non-root
+* Fix isaacs/fstream#1 Only wrap fs one time
+* Fix #3 Start at 1024 max files, then back off on EMFILE
+* lutimes that doens't blow up on Linux
+* A full on-rewrite using a queue instead of just swallowing the EMFILE error
+* Wrap Read/Write streams as well
+
+### 1.0
+
+* Update engines for node 0.6
+* Be lstat-graceful on Windows
+* first
