+
+A cross platform solution to node's spawn and spawnSync.
+
+
+## Installation
+
+`$ npm install cross-spawn`
+
+If you are using `spawnSync` on node 0.10 or older, you will also need to install `spawn-sync`:
+
+`$ npm install spawn-sync`
+
+
+## Why
+
+Node has issues when using spawn on Windows:
+
+- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
+- It does not support [shebangs](http://pt.wikipedia.org/wiki/Shebang)
+- No `options.shell` support on node < v6
+- It does not allow you to run `del` or `dir`
+
+All these issues are handled correctly by `cross-spawn`.
+There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
+
+
+## Usage
+
+Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
+
+
+```js
+var spawn = require('cross-spawn');
+
+// Spawn NPM asynchronously
+var child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+
+// Spawn NPM synchronously
+var results = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+```
+
+
+## Caveats
+
+#### `options.shell` as an alternative to `cross-spawn`
+
+Starting from node v6, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves most of the problems that `cross-spawn` attempts to solve, but:
+
+- It's not supported in node < v6
+- It has no support for shebangs on Windows
+- You must manually escape the command and arguments which is very error prone, specially when passing user input
+
+If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
+
+
+#### Shebangs
+
+While `cross-spawn` handles shebangs on Windows, its support is limited: e.g.: it doesn't handle arguments after the path, e.g.: `#!/bin/bash -e`.
+
+Remember to always test your code on Windows!
+
+
+## Tests
+
