Doxygen

About

Doxygen is a widely used documentation generator that automates the creation of documentation from source code comments. It parses information about classes, functions, and variables, and produces output in formats such as HTML, PDF (via LaTeX), Word (via RTF), and XML. According to the website, it is free, open source, and cross-platform, and supports many languages including C++, C, Python, PHP, Java, C#, and Objective-C.

Doxygen supports Markdown alongside its own commands such as \param, \return, and \brief, to provide additional information about functions, parameters, and return values. It also provides cross-referencing with hyperlinks to related elements, and can generate graphical class hierarchy and collaboration diagrams. Its behavior is controlled through a configuration file (Doxyfile), which lets users adjust settings such as output format and file inclusion or exclusion.

The website text does not describe any Mac-specific features, so this summary reflects the general Doxygen tool rather than a Mac app in particular.
