GNUstep preferences library - development files

 System Preferences is an application which allows one to manage the
 settings of many aspects of the GNUstep environment and its
 applications. The System Preferences application is made of Modules,
 each one a bundle representing a single control panel, and is thus
 extensible and modular.

 This package contains the development files for the PrefrencePanes
 framework, allowing to add additional SystemPreferences bundles.
