<pre>
    [Doxygen grouping](https://www.doxygen.nl/manual/grouping.html) seems not to be available in the AST.

Taking one of the examples from the Doxygen grouping docs:

```c
/**
 * \defgroup IntVariables Global integer variables
 * @{
 */

/** an integer variable */
extern int IntegerVariable;

/**@}*/
```

Dump AST:

```bash
> clang.exe -Xclang -ast-dump -fsyntax-only test.c
