+[![Build Status](https://travis-ci.org/isaacs/rimraf.svg?branch=master)](https://travis-ci.org/isaacs/rimraf) [![Dependency Status](https://david-dm.org/isaacs/rimraf.svg)](https://david-dm.org/isaacs/rimraf) [![devDependency Status](https://david-dm.org/isaacs/rimraf/dev-status.svg)](https://david-dm.org/isaacs/rimraf#info=devDependencies)
+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).
