## Overview

The DOL parser is a hand-written recursive descent parser that handles all DOL syntax constructs. This demo shows parsing various DOL files.

## Summary

| Feature | Parse Status |
|---------|--------------|
| Modules | PASS |
| Functions | PASS |
| Genes | PASS |
| Traits | PASS |
| Constraints | PASS |
| Systems | PASS |
| Exegesis | PASS |

**Conclusion:** The DOL parser successfully handles all language constructs.
