SuperKaramba is a tool, a so-called widget engine, that allows the creation of functionality enhancement modules (desktop widgets) on the KDEdesktop. The desktop widgets are usually embedded directly into the background and do not disturb the normal view of the desktop. The use of SuperKaramba is not limited to KDE, but certain libraries from KDE are required. SuperKaramba had been included in KDE since version 3.5. SuperKaramba is similar to gDesklets for GNOME. The name derives from Portuguese and Spanish super caramba, meaning approximately "super wow" or "super cool" (caramba itself being an euphemism for carallo).
Karamba was originally written by Hans Karlsson as a school project in March 2003. It gained a lot of popularity when it was uploaded to KDE-Look and people began writing themes for it. Karamba only functioned on text files that were written with pseudo-xml format. It became so popular so quickly that Hans had to hand over the project to others who had time to expand upon what he had begun.
By the end of April 2003, Adam Geitgey took over maintenance of the project. He added python scripting support to karamba, which is where it took on a new name, SuperKaramba. Adam kept the project alive, added new features and applied patches from other developers until around April 2005. At that point a group of developers who wanted to move SuperKaramba even further, pushed to get it included in a KDE major release.
SuperKaramba was integrated into KDE 3.5 as part of the kdeutils package, and some of the ideas that it presents have become part of KDE 4’s desktop and panel interface called Plasma, which also has support for the SuperKaramba widgets.
