// create-react-app is installed globally on people's computers. This means
// that it is extremely difficult to have them upgrade the version and
// because there's only one global version installed, it is very prone to
// breaking changes.
//
// The only job of create-react-app is to init the repository and then
// forward all the commands to the local version of create-react-app.
//
// If you need to add a new command, please add it to the scripts/ folder.
//
// The only reason to modify this file is to add more warnings and
// troubleshooting information for the `create-react-app` command.
//
// Do not make breaking changes! We absolutely don't want to have to
// tell people to update their global version of create-react-app.
//
// Also be careful with new language features.
// This file must work on Node 0.10+.
