+// Extended: Like {BufferedProcess}, but accepts a Node script as the command
+// to run.
+//
+// This is necessary on Windows since it doesn't support shebang `#!` lines.
+//
+// ## Examples
+//
+// ```js
+//   const {BufferedNodeProcess} = require('atom')
+// ```
+export default class BufferedNodeProcess extends BufferedProcess {
+
+  // Public: Runs the given Node script by spawning a new child process.
+  //
+  // * `options` An {Object} with the following keys:
+  //   * `command` The {String} path to the JavaScript script to execute.
+  //   * `args` The {Array} of arguments to pass to the script (optional).
+  //   * `options` The options {Object} to pass to Node's `ChildProcess.spawn`
+  //               method (optional).
+  //   * `stdout` The callback {Function} that receives a single argument which
+  //              contains the standard output from the command. The callback is
+  //              called as data is received but it's buffered to ensure only
+  //              complete lines are passed until the source stream closes. After
+  //              the source stream has closed all remaining data is sent in a
+  //              final call (optional).
+  //   * `stderr` The callback {Function} that receives a single argument which
+  //              contains the standard error output from the command. The
+  //              callback is called as data is received but it's buffered to
+  //              ensure only complete lines are passed until the source stream
+  //              closes. After the source stream has closed all remaining data
+  //              is sent in a final call (optional).
