What is Enlightenment (E)?
Enlightenment, also called E, is a popular free and open source (FOSS) windows manager that can serve as a standalone desktop environment. E can also be used along with other desktop environments, such as KDE and GNOME.
Enlightenment is highly customizable and includes the types of themes and high-end graphics familiar to users of Windows and the Mac OS. Many functions can be performed from the keyboard, without the need for mouse manipulation. The command line-driven mode is said to streamline operation. The portable, user-friendly interface is favored by graphics professionals and sophisticated hobbyists.
In addition to the windows manager, E includes a collection of tools to support it and other applications. The three components of the Enlightenment project are Enlightenment DR16, Enlightenment DR17 and the Enlightenment Foundation Libraries.
Carsten 'Rasterman' Haitzler released the first Enlightenment Windows Manager in 1997. Enlightenment DR16 (V.0.16), released in 2000, is still used today. V.16.8.13 was released in May 2008. Enlightenment DR17 (V.0.17), in development, is a complete rewriting of DR16, including a desktop shell. DR17 is expected to enhance graphics quality, improve performance and support new and emerging applications.
