Isn GNU a collection of programming tools that were included in Linux?
People who think that Linux is an entire operating system, if they hear about GNU at all, often get a wrong idea of what GNU is. They may think that GNU is the name of a collection of programs—often they say “programming tools”, since some of our programming tools became popular on their own. The idea that “GNU” is the name of an operating system is hard to fit into a conceptual framework in which that operating system is labeled “Linux”. The GNU Project was named after the GNU operating system—it’s the project to develop the GNU system. (See the 1983 initial announcement.) We developed programs such as GCC, GNU Emacs, GAS, GLIBC, BASH, etc., because we needed them for the GNU operating system. GCC, the GNU Compiler Collection is the compiler that we wrote for the GNU operating system. We, the many people working on the GNU Project, developed Ghostscript, GNUCash, GNU Chess and GNOME for the GNU system too.
