 Doxygen is the de facto standard tool for generating documentation from annotated source code. It supports C++, C, Objective-C, C#, PHP, Java, Python, IDL, Fortran, VHDL, and more. The project is written primarily in C++ (C++17) and uses Flex (`.l` files) for lexical scanning, Python scripts for code generation, and CMake as its build system.
 
-Current version: **1.17.0**
+Current version can be found in the VERSION file in the root of the repository. This is typically the development version (to be released version).
