What does the (X11) mean?
The X Window System, version X11R6, is a set of libraries and programs that implement core components of a Graphical User Interface. As a Unix standard, the XWindow system is consequently able to run on Apple’s Mac OS X and its Darwin core, providing the base for OpenOffice.org 1.1.2 for Mac OS X (X11). The XWindow System is hugely popular with Unix and Linux operating systems, and that support was leveraged to create the version of OpenOffice.org for Mac OS X and Darwin released today. While applications that leverage the XWindow System do not have the Aqua look and feel that Mac users are accustomed to, they are just as functional as any other Mac OS program. This release is designed to function with both Apple’s X11 product and releases from the volunteer XFree86 project.
