kwin-common - 4:6.3.4-2 main

KWin (pronounced as one syllable "kwin") is the window
manager for the KDE Plasma Desktop. It gives you complete
control over your windows, making sure they're not in the way
but aid you in your task. It paints the window decoration,
the bar on top of every window with (configurable) buttons
like close, maximize and minimize. It also handles placing
of windows and switching between them.

This package is part of the KDE base workspace module.
