tracwiki-mode is a major mode for editing Trac-formatted text files in GNU Emacs. tracwiki-mode is free software, licensed under the GNU GPL. Starting in version 0.2, I've pretty much just copypasta'ed most of the original trac-wiki from Shun-ichi GOTO: http://trac-hacks.org/wiki/EmacsWikiEditScript Future versions will include better English, yet more controls, and better customization. Seriously though, without Shun-ichi Goto's work, none of this magic would exist.
