Paying attention to the details is critical especially in writing documentation.

	This snippet checks command-line arguments were provided by the argc arguments.
	We take the first argument (argv[1]), parse it, then take the second argument
	(argv[2]) using Clang_LookupName, and reassigns InstantiationArgs to the third
	argument (argv[3]). In the else case, we decide to go with the "A".

	We take the first argument (`argv[1]`), parse it, then take the second argument

	The code proceeds to instantiate the template B::callme with the given
	type, using the Clang_InstantiateTemplate function from the
	library. The instantiated template is stored in the **Instantiation**.

	A function pointer **callme_fn_ptr** is declared with a type fn_def that represents
	the function taking a void* argument and returning void. The result of
	Clang_GetFunctionAddress is casted by the function pointer.

	The code then creates an object of type `A` using Clang_CreateObject, and the
	pointer to this object is stored in NewA.

	Then the function pointer callme_fn_ptr is called with the NewA, which
	calls the member function B::callme with the instantiated type. Thus, the instantiation
	happens with type `A` and we get the below result.
