EDICT is the outcome of a  voluntary  project  to  produce a freely available
Japanese/English  Dictionary  in  machine-readable  form.   It  was  intended 
initially for use with MOKE (Mark's Own Kanji Editor)  and  related  software 
such as JDIC and JREADER, however it has come to be used in a large number of 
packages.
