System Preferences is an application which allows to manage the settings of many aspects of the gnustep environment and its applications.
System Preferences are made of Modules, each one a bundle representing a single control panel, and is thus extensible and modular.
Technically, it is a clone of the Apple OS X System Preferences and offers a compatible framework.
Currently System Preferences comes with seven preference modules:
Themes, Date & Time, File System, Modifier Keys, Fonts, Defaults and Volumes.
The Color Schemes module is still supplied but not installed by default anymore since its functionality is superseded by the Themes panel. However if Themes are not desired then it can still be installed and used.
The PreferencePanes framework Reference is here.
For installation help, please refer to the INSTALL file included in the System Preferences package.
The latest version of System Preferences can be downloaded here: 1.1.0.
Access to SVN repository by:

The application is now maintained by the GNUstep community, among them Riccardo Mottola who added the Themes module.
