  == Backward compatibility.
  
  Since version 0.3.0, buddy is split into four modules for improved modularity
  of the application and to allow people to include only wanted parts of buddy
  instead of one monolithic library.
  
  Each module has its own functionality and its own documentation. This document/page
  only serves as an introduction to the library and the content of index.
  
  If you are happy with the monolithic version of buddy, you can emulate it by including
  all buddy submodules packages like this:
  
  [source,clojure]
