We would like to thank the following people: - Alexander Rawass for implementing the first version of treemaps for KDirStat (this version has been completely replaced beginning May 2002). - Ben Shneiderman for his ingenious idea of treemaps as an alternative and truly intuitive way of visualizing trees. - All the people at the TU Eindhoven who worked on SequoiaView that gave us the inspiration for including treemaps in KDirStat and numerous papers describing the algorithms behind it. - Harald Fernengel (harry1701@users.sourceforge.net) for continued support for integrating KDirStat with new Qt versions. - Toyohiro Asukai for Asian support patches.
