Kahakai is a fork of the Waimea window manager (www.waimea.org), with the goal of allowing as much internal customization as possible. Kahakai uses SWIG (www.swig.org) to provide wrappers that allow high-level scripting languages to access the internals of the core of the window manager, which is written in C++. NOTE: built with Imlib2 support, so depends on that.

PyGTK allows you to write full featured GTK programs in Python. It is targetted at GTK 2.x, and can be used in conjunction with gnome-python to write Gnome applications. NOTE: this package was compiled WITHOUT GL support.

Imlib 2 is the successor to Imlib. It is not just a newer version - it is a completely new library. Imlib2 can be installed alongside Imlib 1.x without any problems since they are effectively different libraries - but they have very similar functionality.
