LionWiki is a minimalist Wiki engine programmed in PHP. It is extensible, templatable, file based (it doesn't need database like MySQL) and requires just one file to function. It is suitable for small websites, personal notebooks or journals.
Feature set is purposely limited to maintain the biggest advantages over other Wiki engines - small size and simplicity to install and use. LionWiki provides essential Wiki functionality like Wiki syntax, page history, last changes, renaming pages, password protection (both read and write) etc.
