Another possibility beyond those talked about here are using comment-to-documentation formats such as Javadoc or Doxygen, which require to have certain key lines in the comments preceeding a function to describe what happens; the comments are still quite readable within the code, and you've got an easy way to make usable documentation outside of the POD mechanism if your project calls for it.
