High Quality Content by WIKIPEDIA articles! JED is a text editor that makes extensive use of the S-Lang library. It is highly cross-platform compatible; JED runs on Windows and all flavors on Linux and Unix. Older versions are available for DOS. It is also very lightweight (meaning very parsimonious in its use of system resources), which makes it an ideal editor for older systems, embedded systems, etc. JED`s Emacs mode is one of the most faithful emulations available.
