+
+DESCRIPTION = "S-Lang is an interpreted language and a programming library.  The \
+S-Lang language was designed so that it can be easily embedded into \
+a program to provide the program with a powerful extension language. \
+The S-Lang library, provided in this package, provides the S-Lang \
+extension language.  S-Lang's syntax resembles C, which makes it easy \
+to recode S-Lang procedures in C if you need to."
