// grammar file at the runtime.
//
// We do a compilation of the C++ BNF grammar at build time, and generate
// critical data sources. The implementation of the interfaces are based on the
// generated data sources.
//
// FIXME: not everything is fully compiled yet. The implementation of the
// interfaces are still parsing the grammar file at the runtime.
