This is a module for popular in Russia CMS called Bitrix.
This is somewhat useful project that could really be handy for somebody.
It was actually a work task, but it worked out so well that I decided to share it with world.
Basically this module allows you to display contents of any epub book on your bitrix-powered site. This is useful for SEO purposes, as it allows you to gain additional traffic from search results.
