Lack of documentation

In viewing the PHP files from the Starter download, I see that there's no in-file documentation or code comments.
Yes, I have seen the "Developer documentation", but that isn't ideal.

Is a commented version of the PHP files available?

Thanks for the response.

But, why not? It's common sense to include comments, and many JED files include them. It's probably a deal-breaker for me using hikashop at either Starter or Business level.
