Qt-based directory statistics: KDirStat without any KDE,
from the author of the original KDirStat.
QDirStat is a graphical application to show where your disk space
has gone and to help you to clean it up.
This is a Qt-only port of the old Qt3/KDE3-based KDirStat, now
based on the latest Qt 5. It does not need any KDE libs or
infrastructure. It runs on every X11-based desktop on Linux, BSD
and other Unix-like systems.
