+framework for Emacs.  It will help steer you in the right direction when
+you're looking for stuff in Emacs (like buffers, files, etc).  Helm is a fork
+of @code{anything.el} originally written by Tamas Patrovic and can be
+considered to be its successor.  Helm sets out to clean up the legacy code in
+@code{anything.el} and provide a cleaner, leaner and more modular tool, that's
+not tied in the trap of backward compatibility.")
