"Codenamed 'Mars Pathfinder', 2.0 is the first KDE4
stable release, bringing lots of new features and coming with the
entire interface ported to Qt4 libraries.
"Krusader is a powerful, full-featured and highly customisable
file manager. The first time it starts, Krusader will check for
various optional tools it may need, like kdiff3, krename or the
available compression tools in the system (e.g. gzip, bzip2, zip,
rar etc). Then, it will open the preferences window so you can
configure it the way you want before actually start working."
