I have just added my spare-time project about documenting the squid source code using doxygen to the current projects list (devel.squid-cache.org/projects.html#docs)
The aim of this side-project is to make an all-new programmers guide based around code comments. Anyone altering the squid code can assist this project by using a few extra/new habits when they write code comments in the source altered. For starters: block comments (/* */) describing a method, etc. started with /** will be added as documentation when that code makes it into HEAD. Amos
