77 S-Lang is an interpreted language that was designed from the start to be
78 easily embedded into a program to provide it with a powerful extension
79 language. Examples of programs that use S-Lang as an extension language
80 include the jed text editor and the slrn newsreader. Although S-Lang does
81 not exist as a separate application, it is distributed with a quite
82 capable program called slsh ("slang-shell") that embeds the interpreter
83 and allows one to execute S-Lang scripts, or simply experiment with S-Lang
84 at an interactive prompt. Many of the the examples in this document are
85 presented in the context of one of the above applications.
86
87 S-Lang is also a programmer's library that permits a programmer to develop
88 sophisticated platform-independent software. In addition to providing the
89 S-Lang interpreter, the library provides facilities for screen management,
90 keymaps, low-level terminal I/O, etc. However, this document is concerned
91 only with the extension language and does not address these other features
92 of the S-Lang library. For information about the other components of the
93 library, the reader is referred to the S-Lang Library C Programmer's
94 Guide.
