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.
Newfangle is a literate programming technique for LyX (or LaTeX) inspired by notangle. It comes in two parts. The weave part that produces the formatted document is implemented entirely in LaTeX, and the tangle that generates the source code is implemented in awk for portability. Naturally, newfangle is written using literate programming techniques, using itself, and so the source is also the documentation. The source is written using the LyX document editor, an excellent front end to LaTeX. LyX is not required, but newfangle provides formatting support for LyX. Literate programming makes you write good code, because if you can't write a good justification or explanation for your code, it makes you think again and write something that you can explain.
