+// Package cliwrapper is a wrapper that allowing functions to access flag value in an
+// identical way no matter what underlying CLI package used. It brings couple benefits
+// for doing this:
+// 1. Separate CLI function and CLI package.
+// 2. Easier to write test no matter what CLI package actually used.
+// 3. Migrate to new CLI package without changing the way for CLI function to access flag value.
