+This formula was copied from https://github.com/dkanejs/homebrew-aws-session-manager-plugin.
+The change I've made is to REMOVE THE DEPENDENCY ON THE FORMULA awscli, so that you can install
+the plugin using Homebrew even if you don't use the Homebrew version of AWS CLI*
+
+*: Obviously, you still need the AWS CLI. But with this formula you don't have to use to Homebrew-managed version!
