Doxygen is an open source, cross platform, fully supported C, C++, Java, Objective-C, and IDL languages, partially supported by PHP and C#, in a document system similar to the JavaDoc style description. The syntax for annotations is compatible with Qt-Doc, KDoc, and JavaDoc. Doxygen can start with a set of archived source files, generate HTML formatted online class browsers, or offline LATEX and RTF reference manuals.
