Doxygen-related stuff

Code Documentation Examples and Tools

Think that documenting your code is all black and white? Think that there is one "right" way? Think that all developers are in agreement? Think you can call yourself a professional without knowing how to properly document your code? Think again. This "religious" issue was debated on slashdot a while ago.

Core Files and Stuff

Download from the web This should always point to the latest version.
Doxygen related tools More helper tools and scripts for Doxygen.

There is an excellent help file that is included with Doxygen. It explains everything you need to know to use Doxygen. You'll find it in the directory where Doxygen is installed. (It's in the Start menu as well.)

Simple Example (using yet-another Stack class)

Other Related Code Documentation Projects

There are lots of other documentation tools available such as Doxygen, Doc++, ccDoc, Doc-O-Matic, and DocJet. There's a list of free and commercial products here.
Literate Programming Interestingly, this concept has been around for about 20 years.
From the FAQ:
"In general, literate programs combine source and documentation in a single file. Literate programming tools then parse the file to produce either readable documentation or compilable source."
From Donald Knuth:
"Let us change our traditional attitude to the construction of programs: Instead of imagining that our main task is to instruct a computer what to do, let us concentrate rather on explaining to human beings what we want a computer to do."
Tools for Literate Programming Doxygen is just one of dozens of tools for professional developers. There are many other very powerful (some FREE!) tools for communicating your code to humans.
