@itemize

@item Full screen editor with an Emacs look and feel with all Emacs
common features: multi-buffer, multi-window, command mode, universal
argument, keyboard macros, config file with C-like syntax, minibuffer
with completion and history.

@item Can edit files of hundreds of Megabytes without being slow by
using a highly optimized internal representation and by mmaping the
file.

@item Full Unicode support, including multi charset handling (8859-x,
UTF8, SJIS, EUC-JP, ...) and bidirectional editing respecting the
Unicode bidi algorithm.  Arabic and Indic scripts handling (in
progress).

@item WYSIWYG HTML/XML/CSS2 mode graphical editing.  Also supports
Lynx like rendering on VT100 terminals.

@item WYSIWYG DocBook mode based on XML/CSS2 renderer.

@item C mode: coloring with immediate update.  Emacs like auto-indent.

@item Shell mode: colorized VT100 emulation so that your shell work
exactly as you expect.  Compile mode with next/prev error.

@item Input methods for most languages, including Chinese (input
methods come from the Yudit editor).

@item Hexadecimal editing mode with insertion and block commands.
Unicode hexa editing is also supported.

@item Works on any VT100 terminals without termcap.  UTF8 VT100
support included with double width glyphs.

@item X11 support.  Support multiple proportional fonts at the same
time (as XEmacs).  X Input methods supported.  Xft extension supported
for anti aliased font display.

@item Small! Full version (including HTML/XML/CSS2/DocBook rendering
and all charsets): 200KB big.  Basic version (without bidir/unicode
scripts/input/X11/C/Shell/HTML/Dired): 49KB.

It supports syntax highlighting, regular expressions, configurable menus,
keybindings, autocomplete and unlimited undo.  It can pipe a marked block
of text through any command line filter.  It can also open very large binary
files.  It was originally developed on the Amiga 3000T.")
