SCAME is just another one of those ersatz EMACS editors.
The purpose has been to make it look as much as possible like
EMACS on TOPS-20 and AMIS on TOPS-10 and VAX/VMS. A lot of
things are still missing, and some new facilities have been
added to make it fit in better with the UNIX philosophy.

SCAME was first implemented in 1980 on a PDP-11/70 running UNIX
v7 at the University of Linkoeping, Sweden.
