Concurrent Euclid
     
        A concurrent extension of a subset of {Euclid} ("{Simple
        Euclid}") developed by J.R. Cordy and R.C. Holt of the
        {University of Toronto} in 1980.
     
        It features {separate compilation}, {modules}, processes and
        {monitor}s, {signal} and {wait} on {condition variable}s,
        'converters' to defeat {strong type checking}, absolute
        addresses.  All procedures and functions are {re-entrant}.
        {TUNIS} (a {Unix}-like {operating system}) is written in
        Concurrent Euclid.
