a screen oriented version of the classic UNIX text editor ed.

se ('Screen Editor') is a screen oriented version of the classic UNIX text editor ed. The editor implements many of the commands of ed, but instead of being line oriented, se is screen oriented. The command syntax should be very familiar to users who already know ed. If you get lost, there is a built-in help system which describes many of the available commands. Many configurable options can be loaded from a .serc file. The editor can be run interactively or in a script via the included scriptse utility. se runs on a variety of platforms including GNU/Linux, GNU/Hurd, BSD systems, Haiku, Cygwin, Minix, OpenIndiana, and others.

I have been in contact with the last maintainer of se as well as the author of the book that early versions of se were based on (before it had a visual mode). To the best of my knowledge, the original code and my changes are in the public domain.

There are a few output files in the source distribution from autoconf/automake (configure, Makefile, etc) which contain copyright notices. Those notices give unlimited permission to copy and/or distribute the files, with or without modifications, as long as the notices are preserved.

The license of the resulting binary from compiling and linking depends on the license of the terminal library used. The default is ncruses (which has a permissive X11-style license), but termcap, curses, and termlib also can be used.
