Free lionwiki software for mac

LionWiki is extensible, templatable, file based (it doesnt need database like MySQL) and requires just one file to function.
LionWiki is suitable for small websites, journals or personal notebooks.
Design principles:
- Dont use database. Database complicates installation and backuping
- Dont create any own metadata, on the other hand use filesystem metadata to maximum extent
- Keep things simple, stupid, both on source and user level.
- Include only basic features, everything else should be implemented in plugins
- Keep LionWiki usable from just one file

Main features:
- 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.

System requirements:
- PHP enabled web server

Enhancements
- A new directory structure is used, which allows very easy installations no matter how many and which plugins you use. Mbstring conversion and history compression were dropped.
