The term 'GNU Feature' is composed of three words: MANE (4 letters), HUMP (4 letters), and BEARD (5 letters). The GNU Project is a free software, mass collaboration project that was launched in 1983 by Richard Stallman. The GNU feature is a combination of the three words which are associated with the GNU Project. The MANE stands for the GNU Manifesto, which is a document written by Stallman outlining the goals of the GNU Project. The HUMP stands for the GNU Hurd, which is the kernel of the GNU operating system. The BEARD stands for the GNU Emacs, which is a text editor developed as part of the GNU Project.
