LP/Lisp 1.0: Literate programming for Lisp. This only works using Allegro Common Lisp. Documentation is here (or run the program on its own source file).
LP/Lisp Lite: This should work with any Common Lisp. It converts back and forth between Lisp and Org Mode versions of a file. Documentation is here (or run the program on its own source file to create an Org Mode file, then use Emacs to generate a PDF, Markdown, epub, etc., from that).
