;; Copyright (C) 2009, 2011, 2013 Free Software Foundation, Inc.
;;; Commentary:
;;
-;; Eclim version 1.7.13 or newer (?) is required.
+;; Using `emacs-eclim' together with (or instead of) this back-end is
+;; recommended, as it allows you to use other Eclim features.
;;
-;; This completion backend is pretty barebone.
-;;
-;; `emacs-eclim' provides an alternative backend, and it also allows you to
-;; actually control Eclim from Emacs.
+;; The alternative back-end provided by `emacs-eclim' uses `yasnippet'
+;; instead of `company-template' to expand function calls, and it supports
+;; some languages other than Java.
