platform/common/scripts/install-run-rush.js

// THIS FILE WAS GENERATED BY A TOOL. ANY MANUAL MODIFICATIONS WILL GET OVERWRITTEN WHENEVER RUSH IS UPGRADED.
//
// This script is intended for usage in an automated build environment where the Rush command may not have
// been preinstalled, or may have an unpredictable version.  This script will automatically install the version of Rush
// specified in the rush.json configuration file (if not already installed), and then pass a command-line to it.
// An example usage would be:
//
//    node common/scripts/install-run-rush.js install
//
// For more information, see: https://rushjs.io/pages/maintainer/setup_new_repo/
