 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.

 ### Using `options.shell` as an alternative to `cross-spawn`
 
-Starting from node `v4.8`, `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:

 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.
