Show HN: COBOL-REKT, a toolkit for analysing and reverse-engineering COBOL

This is an evolving toolkit of capabilities helpful for analysing and reverse engineering legacy Cobol code. Currently, the following capabilities are available:

- Program / Section-level flowchart generation based on AST (SVG or PNG) - Parse Tree generation (with export to JSON) - Control Flow Tree generation (with export to JSON) - Allows embedding code comments as comment nodes in the graph - The SMOJOL Interpreter (WIP) - Injecting AST and Control Flow into Neo4J - Injecting Cobol data layouts from Data Division into Neo4J (with dependencies like MOVE, COMPUTE, etc.) + export to JSON - Injecting execution traces from the SMOJOL interpreter into Neo4J - Integration with OpenAI GPT to summarise nodes using bottom-up node traversal (AST nodes or Data Structure nodes) - Exposes a unified model (AST, CFG, Data Structures with appropriate interconnections) which can be analysed through [JGraphT](https://jgrapht.org/), together with export to GraphML format and JSON. - Support for namespaces to allow unique addressing of (possibly same) graphs - ALPHA: Support for building Glossary of Variables from data structures using LLMs - ALPHA: Support for extracting Capability Graph from paragraphs of a program using LLMs - ALPHA: Injecting inter-program dependencies into Neo4J (with export to JSON) - ALPHA: Paragraph similarity map

Contributions / use cases are welcome!
