Ding is a dictionary lookup program for the X Window system on Linux/Unix. It comes with a German-English Dictionary with about 253,000 entries. It is based on Tk version >= 8.3 and uses the agrep or egrep tools for searching. In addition ding can also search in English dictionaries using dict(1) and check spelling using ispell(1). It has many configuration options, such as search preferences, interface language (English or German), and colors. It has history and help functions and comes with useful key and mouse bindings for quick and easy lookups.
Dictconv-cx is a dictionary converter that is a stripped down and expanded version of dictconv. It removes support for the DICT dictionary, stardict, as other tools such as makedict handle it well, and adds support for UTF-8 encoding, keywords longer than 255 characters, 82,000+ character length in definitions, and other changes.
