+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
