+ "The traditional vi editor, ported to modern Unix systems.
+
+This implementation is derived from ex/vi 3.7 of 6/7/85 and the BSD
+termcap library, originally from the 2.11BSD distribution. All of them
+were changed to compile and run on newer POSIX compatible Unix systems.
+Support for international character sets was added, including support
+for multibyte locales (based on UTF-8 or East Asian encodings), and some
+changes were made to get closer to the POSIX.2 guidelines for ex and vi.")
