doxygen

Doxygen 1.16.1, released by Dimitri van Heesch as the thirteenth iteration in a long-standing open-source lineage, is a documentation generator that parses annotated C, C++, Java, Python, Fortran, VHDL, PHP, C#, Objective-C and other language sources to extract class hierarchies, function signatures, variable scopes and cross-references, then emits comprehensive manuals in HTML, LaTeX, PDF, RTF, man pages, XML or Microsoft Help formats. Developers embed specially marked comments that the engine scans with a configurable preprocessor, after which it builds hyperlinked call graphs, inheritance diagrams, collaboration charts and source-browser pages that can be styled through custom CSS or LaTeX headers. Typical use cases range from generating API references for single-header libraries to maintaining multi-million-line embedded projects whose teams need synchronized online manuals and offline printable specs; consultants also rely on the tool to reverse-engineer legacy codebases by visualizing dependencies and undocumented interfaces. Because output generation is driven by a plain-text control file, build servers invoke Doxygen in CI pipelines so every commit triggers fresh docs, while IDE plugins display tooltip previews without leaving the editor. The program belongs to the documentation category of the development toolchain ecosystem and is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
