There is a simple tool that automates your ABAP documentation,
keeping it up-to-date with your version of the program.
The documentation is in-code and can be accessed directly from ABAP Workbench.
It interacts the ABAP Dictionary with the code comments, resulting in an interface description of a method or a function module along with the comments.
So the information it generates holds rather a business-value (why stuff happen), than just documenting the code, and therefore can be also useful for project proposals, etc.
