<pre>The Flex and Bison parser generators are becoming an every increasing maintenance burden:
1. More recent versions of this software have undesirable GPL v3 licensing.
2. Different platforms have access to different versions of the software (e.g., Mac is limited to Bison 2.3)
3. Flex and Bison are difficult to obtain and use on Windows.
Instead, it would be nice to move towards a more modern parser generator approach, possibly using something like Boost::spirit.</pre>
