Breathe

Breathe is a Sphinx plugin that provides a bridge between the Sphinx documentation system and Doxygen's XML output. It allows users to integrate Doxygen's comprehensive technical documentation of C, C++, and other languages directly into Sphinx-generated documentation, offering an 'autodoc'-like experience for non-Python projects. The current stable version is 4.36.0, with releases typically occurring a few times a year to maintain compatibility with Sphinx and Doxygen updates.
