+write-file-atomic
+-----------------
+
+This is an extension for node's `fs.writeFile` that makes its operation
+atomic and allows you set ownership (uid/gid of the file).
+
+### var writeFileAtomic = require('write-file-atomic')<br>writeFileAtomic(filename, data, [options], callback)
+
+* filename **String**
+* data **String** | **Buffer**
+* options **Object**
+  * chown **Object**
+    * uid **Number**
+    * gid **Number**
+  * encoding **String** | **Null** default = 'utf8'
+  * mode **Number** default = 438 (aka 0666 in Octal)
+callback **Function**
+
+Atomically and asynchronously writes data to a file, replacing the file if it already
+exists.  data can be a string or a buffer.
+
+The file is initially named `filename + "." + murmurhex(__filename, process.pid, ++invocations)`.
+If writeFile completes successfully then, if passed the **chown** option it will change
+the ownership of the file. Finally it renames the file back to the filename you specified. If
+it encounters errors at any of these steps it will attempt to unlink the temporary file and then
+pass the error back to the caller.
+
+If provided, the **chown** option requires both **uid** and **gid** properties or else
+you'll get an error.
+
+The **encoding** option is ignored if **data** is a buffer. It defaults to 'utf8'.
+
+Example:
+
+```javascript
+writeFileAtomic('message.txt', 'Hello Node', {chown:{uid:100,gid:50}}, function (err) {
+  if (err) throw err;
+  console.log('It\'s saved!');
+});
+```
+
+### var writeFileAtomicSync = require('write-file-atomic').sync<br>writeFileAtomicSync(filename, data, [options])
+
+The synchronous version of **writeFileAtomic**.
