    JE is a fast, feature rich and powerful programming editor written in Java. It has all features a modern editor must have, plus some more. JE can also be used as a editor panel in other Java applications or applets. For installation, just install Java, download the je.jar file, and start the program with "java -jar java.jar" on a command line. For more easy use, create a batch file on your system containing something like "javaw -jar java.jar %1" (Windows syntax shown). The editor will create backups by default, and you can set a backup directory. It creates a .je.cfg configuration file in your home directory for the settings.
