+GNU Scientific Library (GSL) from Common Lisp.  This library provides a
+full range of common mathematical operations useful to scientific and
+engineering applications.  The design of the GSLL interface is such
+that access to most of the GSL library is possible in a Lisp-natural
+way; the intent is that the user not be hampered by the restrictions
+of the C language in which GSL has been written.  GSLL thus provides
+interactive use of GSL for getting quick answers, even for someone not
+intending to program in Lisp.")
