Note that a single Emacs can run both with GUI frames and with terminal
frames at the same time.  E.g. you can start "emacs -nw" and then from
there you can M-x make-frame-on-display RET to open GUI frames.
Or you can run Emacs in "GUI mode", then do M-x server-mode RET, and
then use "emacsclient -t" from a terminal to open a terminal frame.
