Document your source code with Doxygen on Linux

When trying to familiarize yourself with someone else’s project, you usually appreciate the comments left behind that help you understand the meaning of their code. In the same way, whenever you are programming, whether for yourself or for others, it is good practice to comment your own code. All programming languages offer a special syntax to mark a word, a line, or a whole section as a comment. Those areas are then ignored by the compiler or interpreter when the source code is processed.
