/**
 * Jest transformer that will scan a program file (i.e. CLI run file) and make it a module
 * for the CLIRunner instance to run so that jest mocks to work on it.
 *
 * Usage:
 *
 * In your jest.config.js add this transformer
 *
 * {
 *   // other config
 *   transform: {
 *     "\\.[jt]sx?$": "<rootDir>/lib/testing/CLIScriptTester/cliTransformer.js",
 *   },
 *   // Configuration for setting up a cli script
 *   globals: {
 *     cliTransformer: {
 *       cliScripts: [ '.*bin/.*.[jt]s' ]
 *     }
 *   }
 * }
 *
 * The cliTransformer's options are controlled by adding a globals entry in your jest config for cliTransformer
 *
 * The only option at the moment is to add a list of regex strings for 'cliScripts' that should match those scripts
 * that you intend to transform.  Please make sure that you are not transforming unintended files.
