This software is a modified version of the Murrina Gilouche theme specifically designed for GNOME.
But what is GNOME? GNOME is an international effort to build a complete desktop environment from entirely free software. This includes software development frameworks, application selection, and the creation of programs that handle application launching, file handling, and window and task management. GNOME is part of the GNU Project and can be used with various Unix-like operating systems, such as Linux, and can be found as part of the Java Desktop System in Solaris.
The GNOME project values simplicity, usability, and making things "just work." If you value these qualities as well, then Murrina Gilouche Duo may be the perfect theme for you!
