Smartparens is minor mode for Emacs that deals with parens pairs and tries to be smart about it. It started as a unification effort to combine functionality of several existing packages in a single, compatible and extensible way to deal with parentheses, delimiters, tags and the like.

With the basic features found in other packages it also brings many improvements as well as completely new features. Here's a highlight of some features.
