Documentation is an important part of any software. Learn about the Doxygen source tool to aid you in this process!
Doxygen is a free and open source feature-rich automatic documentation generator.
Users very frequently choose to write documentation in the source code itself. Doxygen can automatically extract this documentation from the source code and export it to diverse formats such as browser-based online documentation in html or offline documentation such as Latex manuals, compressed HTML, PostScript, PDF files with hyperlinks, RTF format as well as Unix man pages. Doxygen supports many programming languages.
Doxygen allows documentation to be placed in the header as well as the source files. Doxygen processes markup describing classes, functions, and variables in your software's header/source files and generates a user-friendly hyperlinked set of web pages. These web pages allow the user to navigate all the classes, functions, and variables and see 1) class hierachy relationships; 2) input and output parameters for methods and functions; and 3) other variables and associated data.
