By Joey Hess, Wikis are not just for encyclopedias and Web sites anymore. You can use Ikiwiki in combination with your revision control system to handle issue tracking, news feeds, and other needs of a software project. The wiki can make your bug reports as much a part of your software project as its code, with interesting results. Ikiwiki is a wiki engine with a twist. It's best described by the term "wiki compiler". Just as a typical software project consists of source code that is stored in revision control and compiled with make and gcc, an ikiwiki-based wiki is stored as human editable source in a revision control system, and built into HTML using ikiwiki. Ikiwiki uses your revision control system to track changes and handle tasks such as rolling back changes and merging edits.
