A new Debian package:
DidiWiki is aimed at those who need a quick and lightweight wiki for personal use, such as notes, "to do" lists, etc. It is written in C, and has very low system requirements (binary size of ~25k stripped). This makes it particularly useful for handhelds. DidiWiki does not require installation of a separate webserver, scripting language, or database.
