The GNUstep makefile package is used as a build and runtime environment for SKYRiX applications. The major advantage of gstep-make is that it can build Objective-C based projects on almost any platform (from Linux to Windows) without requiring the developer to know about the complicated compiler options for producing shared libraries or loadable modules.
