Gnu
About
GNU is an operating system which is 100% free software.
It was launched in 1983 by Richard Stallman (rms).
The GNU system contains:
- all of the official GNU software packages,
- and also includes non-GNU free software, notably TeX and the X Window System.
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.
