Elvis
     
         A {vi} lookalike which supports nearly all of the vi/ex
        commands, in both visual mode and colon mode.
     
        Like vi/ex, elvis stores most of the text in a temporary file
        instead of RAM.  This allows it to edit files that are too
        large to fit in a single process' data space.
     
        Elvis runs under {BSD} UNIX, AT&T {SysV} UNIX, {MINIX},
        {MS-DOS}, {Atari TOS}, {Coherent}, {OS9}/68000, {VMS},
        {Windows 95} and {Windows NT}.
     
        Elvis is just as awful to use as vi, so someone will like it.
     
        Version 1.8pl14 (1995-09-04).
