Ion divides the screen into tiles and places windows in these tiles by default. each tile has a set of tabs for the windows within it. it also allows windows to be made 'floating' and placed freely. ion can be controlled through the keyboard alone or together with a mouse.

ion can be configured and extended using the lua language. it also supports extension modules written in c.

this package provides ion version 3. ion version 2 is available in the ion2 package.
