This package contains the "engines" that hide behind the themes for GTK+ and GNOME applications. They redefine the way GTK+ widgets are drawn. The package includes the following engines: * Clearlooks, the default GNOME theme, based on Bluecurve; * Crux, formerly known as the Eazel engine; * High contrast, which is used by some accessibility themes; * Industrial, the famous engine from Novell (formerly Ximian); * LighthouseBlue, another engine based on Bluecurve; * Metal, which gives a metallic look; * Mist, a flat and high performance engine; * Redmond95, which provides a look similar to that of Windows; * ThinIce.

A few sample themes using these engines are also included.
