Molly, a MO-dule for LI-terate programming is a simple self-contained, standalone tool written in core Perl (no extra modules). It creates "Folding HTML" documents out of your Literate Source files on the fly, either as a command line utility or via CGI. It implements a new type of "weaver" for Literate Programming, and has its own built-in tangler. Molly uses the Norman Ramsey "noweb" tool markup (with one sanitizing restricion), and can be used with it. It can also be employed as a standalone script for non-programming purposes to keep notes, long documents, even books in "folding HTML" files.
