DEC Wars
     
        A 1983 {Usenet} posting by Alan Hastings and Steve Tarr
        spoofing the "Star Wars" movies in hackish terms.  Some years
        later, ESR (disappointed by Hastings and Tarr's failure to
        exploit a great premise more thoroughly) posted a
        3-times-longer complete rewrite called "Unix WARS"; the two
        are often confused.
