+node-walk
+====
+
+| Sponsored by [ppl](https://ppl.family)
+
+nodejs walk implementation.
+
+This is somewhat of a port python's `os.walk`, but using Node.JS conventions.
+
+  * EventEmitter
+  * Asynchronous
+  * Chronological (optionally)
+  * Built-in flow-control
+  * includes Synchronous version (same API as Asynchronous)
+
+As few file descriptors are opened at a time as possible.
+This is particularly well suited for single hard disks which are not flash or solid state.
+
+Installation
+----
+
+```bash
+npm install --save walk
+```
+
+Getting Started
+====
+
+```javascript
+(function () {
+  "use strict";
+
+  var walk = require('walk');
+  var fs = require('fs');
+  var walker;
+
+  walker = walk.walk("/tmp", options);
+
+  walker.on("file", function (root, fileStats, next) {
+    fs.readFile(fileStats.name, function () {
+      // doStuff
+      next();
+    });
+  });
+
+  walker.on("errors", function (root, nodeStatsArray, next) {
+    next();
+  });
+
+  walker.on("end", function () {
+    console.log("all done");
+  });
+}());
+```
+
+Common Events
+-----
+
+All single event callbacks are in the form of `function (root, stat, next) {}`.
+
+All multiple event callbacks callbacks are in the form of `function (root, stats, next) {}`, except **names** which is an array of strings.
+
+All **error** event callbacks are in the form `function (root, stat/stats, next) {}`.
+**`stat.error`** contains the error.
+
+* `names`
+* `directory`
+* `directories`
+* `file`
+* `files`
+* `end`
+* `nodeError` (`stat` failed)
+* `directoryError` (`stat` succedded, but `readdir` failed)
+* `errors` (a collection of any errors encountered)
+
+
+A typical `stat` event looks like this:
+
+```javascript
+{ dev: 16777223,
+  mode: 33188,
+  nlink: 1,
+  uid: 501,
+  gid: 20,
+  rdev: 0,
+  blksize: 4096,
+  ino: 49868100,
+  size: 5617,
+  blocks: 16,
+  atime: Mon Jan 05 2015 18:18:10 GMT-0700 (MST),
+  mtime: Thu Sep 25 2014 21:21:28 GMT-0600 (MDT),
+  ctime: Thu Sep 25 2014 21:21:28 GMT-0600 (MDT),
+  birthtime: Thu Sep 25 2014 21:21:28 GMT-0600 (MDT),
+  name: 'README.md',
+  type: 'file' }
+```
+
+Advanced Example
+====
+
+Both Asynchronous and Synchronous versions are provided.
+
+```javascript
+(function () {
+  "use strict";
+
+  var walk = require('walk');
+  var fs = require('fs');
+  var options;
+  var walker;
+
+  options = {
+    followLinks: false
+    // directories with these keys will be skipped
+  , filters: ["Temp", "_Temp"]
+  };
+
+  walker = walk.walk("/tmp", options);
+
+  // OR
+  // walker = walk.walkSync("/tmp", options);
+
+  walker.on("names", function (root, nodeNamesArray) {
+    nodeNamesArray.sort(function (a, b) {
+      if (a > b) return 1;
+      if (a < b) return -1;
+      return 0;
+    });
+  });
+
+  walker.on("directories", function (root, dirStatsArray, next) {
+    // dirStatsArray is an array of `stat` objects with the additional attributes
+    // * type
+    // * error
+    // * name
+
+    next();
+  });
+
+  walker.on("file", function (root, fileStats, next) {
+    fs.readFile(fileStats.name, function () {
+      // doStuff
+      next();
+    });
+  });
+
+  walker.on("errors", function (root, nodeStatsArray, next) {
+    next();
+  });
+
+  walker.on("end", function () {
+    console.log("all done");
+  });
+}());
+```
+
+### Sync
+
+Note: You **can't use EventEmitter** if you want truly synchronous walker
+(although it's synchronous under the hood, it appears not to be due to the use of `process.nextTick()`).
+
+Instead **you must use `options.listeners`** for truly synchronous walker.
+
+Although the sync version uses all of the `fs.readSync`, `fs.readdirSync`, and other sync methods,
+I don't think I can prevent the `process.nextTick()` that `EventEmitter` calls.
+
+```javascript
+(function () {
+  "use strict";
+
+  var walk = require('walk');
+  var fs = require('fs');
+  var options;
+  var walker;
+
+  // To be truly synchronous in the emitter and maintain a compatible api,
+  // the listeners must be listed before the object is created
+  options = {
+    listeners: {
+      names: function (root, nodeNamesArray) {
+        nodeNamesArray.sort(function (a, b) {
+          if (a > b) return 1;
+          if (a < b) return -1;
+          return 0;
+        });
+      }
+    , directories: function (root, dirStatsArray, next) {
+        // dirStatsArray is an array of `stat` objects with the additional attributes
+        // * type
+        // * error
+        // * name
+
+        next();
+      }
+    , file: function (root, fileStats, next) {
+        fs.readFile(fileStats.name, function () {
+          // doStuff
+          next();
+        });
+      }
+    , errors: function (root, nodeStatsArray, next) {
+        next();
+      }
+    }
+  };
+
+  walker = walk.walkSync("/tmp", options);
+
+  console.log("all done");
+}());
+```
+
+API
+====
+
+Emitted Values
+
+  * `on('XYZ', function(root, stats, next) {})`
+
+  * `root` - the containing the files to be inspected
+  * *stats[Array]* - a single `stats` object or an array with some added attributes
+    * type - 'file', 'directory', etc
+    * error
+    * name - the name of the file, dir, etc
+  * next - no more files will be read until this is called
+
+Single Events - fired immediately
+
+  * `end` - No files, dirs, etc left to inspect
+
+  * `directoryError` - Error when `fstat` succeeded, but reading path failed (Probably due to permissions).
+  * `nodeError` - Error `fstat` did not succeeded.
+  * `node` - a `stats` object for a node of any type
+  * `file` - includes links when `followLinks` is `true`
+  * `directory` - **NOTE** you could get a recursive loop if `followLinks` and a directory links to its parent
+  * `symbolicLink` - always empty when `followLinks` is `true`
+  * `blockDevice`
+  * `characterDevice`
+  * `FIFO`
+  * `socket`
+
+Events with Array Arguments - fired after all files in the dir have been `stat`ed
+
+  * `names` - before any `stat` takes place. Useful for sorting and filtering.
+    * Note: the array is an array of `string`s, not `stat` objects
+    * Note: the `next` argument is a `noop`
+
+  * `errors` - errors encountered by `fs.stat` when reading ndes in a directory
+  * `nodes` - an array of `stats` of any type
+  * `files`
+  * `directories` - modification of this array - sorting, removing, etc - affects traversal
+  * `symbolicLinks`
+  * `blockDevices`
+  * `characterDevices`
+  * `FIFOs`
+  * `sockets`
+
+**Warning** beware of infinite loops when `followLinks` is true (using `walk-recurse` varient).
+
+Comparisons
+====
+
+Tested on my `/System` containing 59,490 (+ self) directories (and lots of files).
+The size of the text output was 6mb.
+
+`find`:
+    time bash -c "find /System -type d | wc"
+    59491   97935 6262916
+
+    real  2m27.114s
+    user  0m1.193s
+    sys 0m14.859s
+
+`find.js`:
+
+Note that `find.js` omits the start directory
+
+    time bash -c "node examples/find.js /System -type d | wc"
+    59490   97934 6262908
+
+    # Test 1
+    real  2m52.273s
+    user  0m20.374s
+    sys 0m27.800s
+
+    # Test 2
+    real  2m23.725s
+    user  0m18.019s
+    sys 0m23.202s
+
+    # Test 3
+    real  2m50.077s
+    user  0m17.661s
+    sys 0m24.008s
+
+In conclusion node.js asynchronous walk is much slower than regular "find".
