+
+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.")
