* Examples in C++

You can run `make` to compile these examples.  And `make clean` to tidy
afterwards.

** simple.yy - Simple example in C++14
A very simple example in C++, based on variants and symbol constructors.
Variants allow to use any C++ type as semantic value type, and symbol
constructors ensure consistency between declared token type and effective
semantic value.

Run as `./simple`.

Extracted from the documentation: "A Simple C++ Example".
https://www.gnu.org/software/bison/manual/html_node/A-Simple-C_002b_002b-Example.html

** variant.yy - Self-contained example in C++98
A variation of simple.yy, in C++98.

Run as `./variant`.

** variant-11.yy - Self-contained example in modern C++
Another variation of simple.yy, closely related to the previous one, but
exhibiting support for C++11's move semantics.

Run as `./variant` or `./variant NUMBER`.
