Standardese aims to be a nextgen Doxygen.
It consists of two parts: a library and a tool.
The library aims at becoming the documentation frontend that can be easily extended and customized. It parses C++ code with the help of libclang and provides access to it.
The tool drives the library to generate documentation for user-specified files. It supports a couple of output formats including Markdown and HTML as well as experimental Latex and Man pages.
