There are many wiki sites on the web, wikipedia being the largest and most popular. Wiki webs are not the only place a system with non-HTML markups, cross link generation, revision control, collaborative editing and optionally access control list can find a good use. However, most of the available wiki softwares are monolithic. It is very difficult to integrate a wiki with other applications, web or non-web, beyond the trivial hyperlinking. Inspired by the trac project, the author created a simplified wiki system that can be embedded into other applications. A brief description of the system will be given along with some example applications.
