This directory contains the MacOS-specific code for building a Cocoa version of xscreensaver without using X11. To build it, just type "make", or use the included XCode project. The executables will show up in the "build/Release/" and/or "build/Debug/" directories. To build these programs, XCode 2.4 or later is required. To run them, MacOS 10.4.0 or later is required.
