The MUD++ text editor.

Several modes of editing are provided:

	Append mode for typing long multiline text.
	Line mode for editing or correcting single lines.

From command mode you must type 'append' or 'a' to go into
append mode. End with a '~' or '@' on a empty line.
To clear the buffer enter '.c' on an empty line.

While in command mode these are the recognized commands.
