Gitit is a wiki program written in Haskell. It uses Happstack for the web server and pandoc for markup processing. Pages and uploaded files are stored in a git, darcs, or mercurial repository and may be modified either by using the VCS's command-line tools or through the wiki's web interface. By default, pandoc's extended version of markdown is used as a markup language, but reStructuredText, LaTeX, HTML, DocBook, or Emacs Org-mode markup can also be used. Pages can be exported in a number of different formats, including LaTeX, RTF, OpenOffice ODT, and MediaWiki markup. Gitit can be configured to display TeX math (using texmath) and highlighted source code (using highlighting-kate).
