Definition: GNU Emacs, a popular text editor used for writing, debugging, and editing applications in GNU/Linux, was designed by a team from Japan called "SUSE." It's known for being free and open-source software. The term 'gnuemacs' refers to the GNU version of Emacs, which is the core version. This version supports various features such as syntax highlighting, autocomplete, and debugging tools. The term "emacs" itself was derived from the word 'elegant', which means graceful or elegant.
