ikiwiki is a wiki compiler, a wiki engine, particularly suited to personal wikis, project wikis or blogs. It is released for free under the GNU General Public License v2 (or later) (GPL v2). It converts wiki pages into html pages suitable for publishing on a website. Unlike most other wiki engines, ikiwiki stores pages and history as plain text files in a standard revision control system such as Subversion or Git, rather than some specialized internal page history format.
The ikiwiki wiki engine is written in Perl by Joey (and others), and there is a plugin available that supports LaTeX math, along with other plugins to support other common wiki syntaxes. ikiwiki supports using Git, Subversion, Mercurial, Monotone, darcs, or CVS version control systems. ikiwiki can also be used to build weblogs.
Their website (also named ikiwiki) is a wiki, running the ikiwiki wiki engine, demonstrating and discussing the ikiwiki wiki engine.
