emg
emg, or Ersatz Mg, is a very tiny Emacs-like text editor created by combining elements of Ersatz Emacs and Mg.
emg has two versions: emg-retro and emg-modern. emg-retro is the original version of emg and is specifically designed for RetroBSD. As emg-retro is a part of the RetroBSD base system, this repo is for development only. emg-retro will most likely not be able to compile on a modern system.
emg-modern is a newer version of emg and can compile and run on nearly any modern POSIX system. It also has more features than emg-retro, making it among the collection of ersatz emacsen.

emg is Public Domain, because Ersatz Emacs and Mg are both Public Domain and it would be insulting to all involved to change that.
