slang 2.3.2 Library for interactive applications and extensibility
S-Lang is a multi-platform programmer's library designed to allow a developer to create robust multi-platform software. It provides facilities required by interactive applications such as display/screen management, keyboard input, keymaps, and so on. The most exciting feature of the library is the slang interpreter that may be easily embedded into a program to make it extensible. While the emphasis has always been on the embedded nature of the interpreter, it may also be used in a stand-alone fashion through the use of slsh, which is part of the S-Lang distribution.
