| dc.description.abstract | LSB (for Layered System Building) is an integrated set of facilities for aiding in the construction of highly-modular, multi-layered, implementation-independent Lisp systems. It provides for conditional inclusion of source text, documentation production, automated declarations, and "high-level" definitions. Lisp code compiled with LSB in general does not require LSB in its run-time environment. LSB has been in use for some time in PDP-10 Maclisp, is operation in Multics Maclisp and Lisp Machine Lisp, and is being developed for NIL. | en_US |
