// don't hoist binaries provided by nested dependencies, so to consistently define a program named
// "jest" we use this proxy script.
//
// We forward all arguments and stdio streams to the real "jest" program and exit with the same
// signal or status code.
//
// If you need to run Jest with the JS debugger enabled, run Jest directly. It is usually under
// node_modules/jest/bin/jest.js.
