PukiWiki ('PoohKeyWeKey' without any prolonged sounds, comes from 'PHP' and 'YukiWiki') is a wiki implementation that works on PHP 4 and 5, outputs XHTML 1.1, has many plugins (including one for bug tracking) and skins (such as one for embedded browsers), enables English and/or UTF-8 configuration, and features case-insensitive WikiNames. The formatting rules are based on YukiWiki. 'B-Wiki' and 'PukiWikiMod' are ported ones to XOOPS.
