Very old, very crusty, full screen editor based on MicroEMACS 3.9e.
Please don't use this, the whole thing only exists and is (badly) maintained because I have been using this thing for decades, and my fingers cannot be retrained from the strange keybindings this old version of uemacs uses.
Despite the name, the keybindings bear only passing resemblance to real emacs, and the choices also tend to be incompatible with other editors even when those editors keybindings are configurable.
This is a bad editor. Really. Unless you have used it since the 1980s, and have untrainable fingers, you should absolutely walk away and never look back. I've updated it minimally over the years to keep it kind of working, but only kind of.
So this is a simplistic editor, written for an age when you had 64kB limits and 300 or 1200 baud terminals were common. It was not a better age, and this is not a better editor.
