The GNU system contains all of the official GNU software packages (which are listed below), and also includes non-GNU free software, notably TeX and the X Window System. Also, the GNU system is not a single static set of programs; users and distributors may select different packages according to their needs and desires. The result is still a variant of the GNU system.
