libplasma3 4:4.14.0-0ubuntu3 (amd64 binary) in ubuntu utopic

 This package contains the Plasma library. Plasma is one of the key
 technologies of KDE 4 (also known as the "Pillars of KDE"), and one of the
 most visible to users. It is the component that is "in charge" of the desktop
 interface; the desktop, panel (often referred simply as the task bar), and
 related elements. Plasma aims to change the traditional concepts of the
 "Desktop", incorporating semantic application elements, and bringing
 cooperating technologies to the user's fingertips in a way that is visually
 appealing while easing work flow.
 .
 It is part of the KDE Development Platform libraries module.
