+     "WordNet® is a large lexical database of English.  Nouns, verbs,
+adjectives and adverbs are grouped into sets of cognitive synonyms
+(synsets), each expressing a distinct concept.  Synsets are interlinked by
+means of conceptual-semantic and lexical relations.  The resulting network of
+meaningfully related words and concepts can be navigated with the browser.
+WordNet is also freely and publicly available for download.  WordNet's
+structure makes it a useful tool for computational linguistics and natural
+language processing.")
