If you're one of "those programmers" who documents everything you do (you do document, don't you?) - then you might want to check out the latest version of phpDocumetor (v1.2.2)

The phpDocumentor team is pleased to announce the release of phpDocumentor 1.2.2. Several critical bugs were discovered in the implementation of HighlightParser, post-processing of tutorials. In addition, the algorithm used to find file-level documentation was changed to be more natural. All users should upgrade existing installations to 1.2.2. phpDocumentor is a complete documentation solution for PHP. Generates javaDoc-style API documentation and user-level manuals from your PHP code.

This is a great tool for programmers out there that want some nice, easy to use documentation, but don't want the hassle of throwing it together themselves. You just comment your code (which helps anyway) and phpDocumentor does the rest. Simple, right? So, now you don't have any more excuses not to document your code...
