+/**
+ * @fileoverview
+ *
+ * This file is used to bootstrap the CLI process by dynamically importing the main initialization code.
+ * This is done to allow the main bin file (`ng`) to remain CommonJS so that older versions of Node.js
+ * can be checked and validated prior to the execution of the CLI. This separate bootstrap file is
+ * needed to allow the use of a dynamic import expression without crashing older versions of Node.js that
+ * do not support dynamic import expressions and would otherwise throw a syntax error. This bootstrap file
+ * is required from the main bin file only after the Node.js version is determined to be in the supported
+ * range.
