Wixi is a multi-platform wiki application for the desktop. It is written in python/wxpython and uses an sqlite3 database for indexing pages. Wixi uses the popular txt2tags markup language for generating it's pages.
Using Wixi does not mean learning yet another markup. Txt2tags exists for more than 7 years and is used by many authors writing documentation. The txt2tags marks are very simple and almost natural. You can even choose not to edit in Wixi but in your favorite text editor and than import them on a later time.
A repository is a place where all your wiki's are located. This includes all images, plugins and exported pages. For example, your repository may look like this:
/MyWiki /MyWiki/Slackware.sl3 /MyWiki/System.sl3 /MyWiki/images/ /MyWiki/images/NewPage.png /MyWiki/images/SettingsPanel.png
