+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** | **String**
+  * chown **Object** default, uid & gid of existing file, if any
+    * uid **Number**
+    * gid **Number**
+  * encoding **String** | **Null** default = 'utf8'
+  * fsync **Boolean** default = true
+  * mode **Number** default, from existing file, if any
+  * Promise **Object** default = native Promise object
+* 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)`.
+Note that `require('worker_threads').threadId` is used in addition to `process.pid` if running inside of a worker thread.
+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 multiple writes are concurrently issued to the same file, the write operations are put into a queue and serialized in the order they were called, using Promises. Native promises are used by default, but you can inject your own promise-like object with the **Promise** option. Writes to different files are still executed in parallel.
+
+If provided, the **chown** option requires both **uid** and **gid** properties or else
+you'll get an error.  If **chown** is not specified it will default to using
+the owner of the previous file.  To prevent chown from being ran you can
+also pass `false`, in which case the file will be created with the current user's credentials.
+
+If **mode** is not specified, it will default to using the permissions from
+an existing file, if any.  Expicitly setting this to `false` remove this default, resulting
+in a file created with the system default permissions.
+
+If options is a String, it's assumed to be the **encoding** option. The **encoding** option is ignored if **data** is a buffer. It defaults to 'utf8'.
+
+If the **fsync** option is **false**, writeFile will skip the final fsync call.
+
+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**.
