Elvis is a clone of vi/ex, the standard UNIX editor. It supports
nearly all of the vi/ex commands, in both visual mode and ex mode.
Elvis adds support for multiple files, multiple windows, a variety of
display modes (including syntax highlighting, man, tex, html and
hex), an optional X11 user interface (see elvis-x11), on-line help,
folding, spell checking, new options, auto commands, regions, enhanced
tags, printing, aliases and an improved :map command.
.
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.
Also, the edit buffer can survive a power failure or crash.
