description: It is first paper in my blog (I think I need something here for tests =)). There are many similar articles, and I'll not be an exception. I just want to show my <code>.zshrc</code> and explain what it does and why it is needed. Also any comments or additions are welcome. It is a translated paper from Russian (<a href="http://archlinux.org.ru/forum/topic/12752/">original</a>).
