The shared library for the S-Lang extension language

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.
