gNewSense is a computer operating system based on Debian, and developed with sponsorship from the Free Software Foundation. Its goal is user-friendliness, but with all proprietary (e.g. binary blobs) and non-free software removed. The Free Software Foundation considers gNewSense to be composed entirely of free software. gNewSense takes a relatively strict stance against proprietary software. For example, any documentation that gives instructions on installing proprietary software is excluded. By default gNewSense uses GNOME. The graphical user interface can be customized with the user's choice of X display manager, window managers, and other desktop environments available to install through its hosted repositories. The Ubiquity installer allows installing to the hard disk from within the Live CD environment without the need for restarting the computer prior to installation. Besides standard system tools and other small applications, gNewSense comes installed with the following software: the OpenOffice.org productivity suite, the Epiphany Internet browser recently renamed to simply "Web", the Empathy instant messenger, and the GIMP for editing photos and other raster graphics. Common software development tools including the GCC are installed by default.
