+	  Joe's Own Editor
+
+	  JOE is an easy-to-use, full featured terminal-based screen editor.
+	  Its behavior is a blending of WordStar and GNU-EMACS (but it does
+	  not use code from either program).  It is a great editor for new
+	  users or as an alternative to vi.

+	  Install all rc and syntax highlighting files. Without this option
+	  only the joe binary is installed, which contains a default
+	  configuration.
