DictEm is a customizable DICT client for (X)Emacs. It implements all functions of the client part of the DICT protocol (RFC-2229). Unlike dictionary.el, it widely uses autocompletion that is used for selecting a dictionary and search strategy. It also provides several hooks that may be used for buffer postprocessing. Built-in hyperlinking and a highlighting mechanisms are based on this ability. Also, DictEm supports the mechanism of virtual dictionaries that can be used for grouping dictionaries from _different_ DICT servers into the client-side virtual dictionary.
