        2. a unix command interpreter shell by paul falstad
         some time before 1993-03-23.  it is similar
        to, but not completely compatible with, ksh, with many
        additions to please csh users and some tcsh features.  zsh
        supports editing of multi-line commands in a single buffer;
        variable editing; a command buffer stack; recursive
        globbing; manipulation of arrays; and spelling correction.
     
        zsh uses gnu autoconf so should compile and run on any
        modern version of unix, and many not-so-modern.
     
        current version: 4.0.6, as of 2002-10-02.
