## Generation of Python struct from Cobol Copybook Parser

The RRC datasets have PDF files that define the COBOL Copybook statements.
It would be nice to be able to pass these copybook fragments into a python tool
that would then generate the struct format for parsing the raw binary stream.

The work under [Cobol Parser](src/cobol_parser.md) addresses this desire.
