## Different Behavior

If the spawned process exits with a non-zero code, an `ExitCodeError` is thrown with the original
command, code, `stdout`, and `stderr` as properties.

If the spawned process is terminated by a signal on non-Windows platforms, an `ExitSignalError` is
thrown with the original command, signal name, `stdout`, and `stderr` as properties.

## Extra Options

- `logger`: a `Function` such as `console.log` or `debug(name)` to log some information
  about the spawned process.
- `updateErrorCallback`: a callback which mutates the error before it is re-thrown. Most commonly,
  this is used to augment the error message of `ENOENT` error to provide a more human-friendly
  message as to how to install the missing executable.
