Gitit is a wiki backed by a git, darcs, or mercurial filestore.  Pages
and uploaded files can be modified either directly via the VCS's
command-line tools or through the wiki's web interface.  Pandoc is used
for markup processing, so pages may be written in (extended) markdown,
reStructuredText, LaTeX, HTML, or literate Haskell, and exported in ten
different formats, including LaTeX, ConTeXt, DocBook, RTF, OpenOffice
ODT, and MediaWiki markup.

Notable features include:

 * plugins: dynamically loaded page transformations written in Haskell.
 * conversion of TeX math to MathML for display in web browsers.
 * syntax highlighting of source code files and code snippets.
 * Atom feeds (site-wide and per-page).
 * a library, Network.Gitit, that makes it simple to include a gitit
   wiki in any happstack application.
